2013-01-15 20:24:21), which is a library of common routines intended to be shared at the source level. Copyright (C) 2004-2013 Free Software Foundation, Inc. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". 1 Brief Overview **************** Gnulib is a source code library that provides basic functionality to programs and libraries. Many software packages make use of Gnulib to avoid reinventing the portability wheel. Resources: * Gnulib is hosted at Savannah: `http://savannah.gnu.org/projects/gnulib'. Get the sources through Git or CVS from there. * The Gnulib home page: `http://www.gnu.org/software/gnulib/'. 1.1 Gnulib Basics ================= While portability across operating systems is not one of GNU's primary goals, it has helped introduce many people to the GNU system, and is worthwhile when it can be achieved at a low cost. This collection helps lower that cost. Gnulib is intended to be the canonical source for most of the important "portability" and/or common files for GNU projects. These are files intended to be shared at the source level; Gnulib is not a typical library meant to be installed and linked against. Thus, unlike most projects, Gnulib does not normally generate a source tarball distribution; instead, developers grab modules directly from the source repository. The easiest, and recommended, way to do this is to use the `gnulib-tool' script. Since there is no installation procedure for Gnulib, `gnulib-tool' needs to be run directly in the directory that contains the Gnulib source code. You can do this either by specifying the absolute filename of `gnulib-tool', or by using a symbolic link from a place inside your `PATH' to the `gnulib-tool' file of your preferred Gnulib checkout. For example: $ ln -s $HOME/gnu/src/gnulib.git/gnulib-tool $HOME/bin/gnulib-tool 1.2 git and CVS =============== Gnulib is available for anonymous checkout. In any Bourne-shell the following should work: $ git clone git://git.sv.gnu.org/gnulib.git For a read-write checkout you need to have a login on `savannah.gnu.org' and be a member of the Gnulib project at `http://savannah.gnu.org/projects/gnulib'. Then, instead of the URL `git://git.sv.gnu.org/gnulib', use the URL `ssh://USER@git.sv.gnu.org/srv/git/gnulib' where USER is your login name on savannah.gnu.org. git resources: Overview: `http://en.wikipedia.org/wiki/Git_(software)' Homepage: `http://git-scm.com/' When you use `git annotate' or `git blame' with Gnulib, it's recommended that you use the `-w' option, in order to ignore massive whitespace changes that happened in 2009. CVS checkouts are also supported: $ cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/gnulib.git co -d gnulib HEAD 1.3 Keeping Up-to-date ====================== The best way to work with Gnulib is to check it out of git. To synchronize, you can use `git pull', or `cvs update -dP' if you are still using CVS. Subscribing to the mailing list will help you to plan when to update your local copy of Gnulib (which you use to maintain your software) from git. You can review the archives, subscribe, etc., via `https://lists.gnu.org/mailman/listinfo/bug-gnulib'. Sometimes, using an updated version of Gnulib will require you to use newer versions of GNU Automake or Autoconf. You may find it helpful to join the autotools-announce mailing list to be advised of such changes. 1.4 Contributing to Gnulib ========================== All software here is copyrighted by the Free Software Foundation--you need to have filled out an assignment form for a project that uses the module for that contribution to be accepted here. If you have a piece of code that you would like to contribute, please email . Generally we are looking for files that fulfill at least one of the following requirements: * If your `.c' and `.h' files define functions that are broken or missing on some other system, we should be able to include it. * If your functions remove arbitrary limits from existing functions (either under the same name, or as a slightly different name), we should be able to include it. If your functions define completely new but rarely used functionality, you should probably consider packaging it as a separate library. 1.4.1 Gnulib licensing ---------------------- Gnulib contains code both under GPL and LGPL. Because several packages that use Gnulib are GPL, the files state they are licensed under GPL. However, to support LGPL projects as well, you may use some of the files under LGPL. The "License:" information in the files under modules/ clarifies the real license that applies to the module source. Keep in mind that if you submit patches to files in Gnulib, you should license them under a compatible license, which means that sometimes the contribution will have to be LGPL, if the original file is available under LGPL via a "License: LGPL" information in the projects' modules/ file. 1.4.2 Indent with spaces not TABs --------------------------------- We use space-only indentation in nearly all files. This includes all `*.h', `*.c', `*.y' files, except for the `regex' module. Makefile and ChangeLog files are excluded, since TAB characters are part of their format. In order to tell your editor to produce space-only indentation, you can use these instructions. * For Emacs: Add these lines to your Emacs initialization file (`$HOME/.emacs' or similar): ;; In Gnulib, indent with spaces everywhere (not TABs). ;; Exceptions: Makefile and ChangeLog modes. (add-hook 'find-file-hook '(lambda () (if (and buffer-file-name (string-match "/gnulib\\>" (buffer-file-name)) (not (string-equal mode-name "Change Log")) (not (string-equal mode-name "Makefile"))) (setq indent-tabs-mode nil)))) * For vi (vim): Add these lines to your `$HOME/.vimrc' file: " Don't use tabs for indentation. Spaces are nicer to work with. set expandtab For Makefile and ChangeLog files, compensate for this by adding this to your `$HOME/.vim/after/indent/make.vim' file, and similarly for your `$HOME/.vim/after/indent/changelog.vim' file: " Use tabs for indentation, regardless of the global setting. set noexpandtab * For Eclipse: In the "Window|Preferences" dialog (or "Eclipse|Preferences" dialog on Mac OS), 1. Under "General|Editors|Text Editors", select the "Insert spaces for tabs" checkbox. 2. Under "C/C++|Code Style", select a code style profile that has the "Indentation|Tab policy" combobox set to "Spaces only", such as the "GNU [built-in]" policy. If you use the GNU indent program, pass it the option `--no-tabs'. 1.4.3 How to add a new module ----------------------------- * Add the header files and source files to `lib/'. * If the module needs configure-time checks, write an Autoconf macro for it in `m4/MODULE.m4'. See `m4/README' for details. * Write a module description `modules/MODULE', based on `modules/TEMPLATE'. * If the module contributes a section to the end-user documentation, put this documentation in `doc/MODULE.texi' and add it to the "Files" section of `modules/MODULE'. Most modules don't do this; they have only documentation for the programmer (= Gnulib user). Such documentation usually goes into the `lib/' source files. It may also go into `doc/'; but don't add it to the module description in this case. * Add the module to the list in `MODULES.html.sh'. You can test that a module builds correctly with: $ ./gnulib-tool --create-testdir --dir=/tmp/testdir module1 ... moduleN $ cd /tmp/testdir $ ./configure && make Other things: * Check the license and copyright year of headers. * Check that the source code follows the GNU coding standards; see `http://www.gnu.org/prep/standards'. * Add source files to `config/srclist*' if they are identical to upstream and should be upgraded in Gnulib whenever the upstream source changes. * Include header files in source files to verify the function prototypes. * Make sure a replacement function doesn't cause warnings or clashes on systems that have the function. * Autoconf functions can use `gl_*' prefix. The `AC_*' prefix is for autoconf internal functions. * Build files only if they are needed on a platform. Look at the `alloca' and `fnmatch' modules for how to achieve this. If for some reason you cannot do this, and you have a `.c' file that leads to an empty `.o' file on some platforms (through some big `#if' around all the code), then ensure that the compilation unit is not empty after preprocessing. One way to do this is to `#include ' or `' before the big `#if'. 1.4.4 Portability guidelines ---------------------------- Gnulib code is intended to be portable to a wide variety of platforms, not just GNU platforms. See the documentation section "Target Platforms" for details. Many Gnulib modules exist so that applications need not worry about undesirable variability in implementations. For example, an application that uses the `malloc' module need not worry about `malloc (0)' returning `NULL' on some Standard C platforms; and `time_r' users need not worry about `localtime_r' returning `int' (not `char *') on some platforms that predate POSIX 1003.1-2001. Currently we assume at least a freestanding C89 compiler, possibly operating with a C library that predates C89. The oldest environments currently ported to are probably HP-UX 10.20 and IRIX 5.3, though we are not testing these platforms very often. Because we assume a freestanding C89 compiler, Gnulib code can include `', `', `', and `' unconditionally. It can also assume the existence of `', `', `', `', `', `', `', `', and `'. Similarly, many modules include `' even though it's not even in C99; that's OK since `' has been around nearly forever. Even if the include files exist, they may not conform to C89. However, GCC has a `fixincludes' script that attempts to fix most C89-conformance problems. So Gnulib currently assumes include files largely conform to C89 or better. People still using ancient hosts should use fixincludes or fix their include files manually. Even if the include files conform to C89, the library itself may not. For example, `strtod' and `mktime' have some bugs on some platforms. You can work around some of these problems by requiring the relevant modules, e.g., the Gnulib `mktime' module supplies a working and conforming `mktime'. The GNU coding standards allow one departure from strict C99: Gnulib code can assume that standard internal types like `size_t' are no wider than `long'. POSIX 1003.1-2001 and the GNU coding standards both require `int' to be at least 32 bits wide, so Gnulib code assumes this as well. Gnulib code makes the following additional assumptions: * Signed integer arithmetic is two's complement. Previously, Gnulib code sometimes assumed that signed integer arithmetic wraps around, but modern compiler optimizations sometimes do not guarantee this, and Gnulib code with this assumption is now considered to be questionable. *Note Integer Properties::. Some Gnulib modules contain explicit support for the other signed integer representations allowed by C99 (ones' complement and signed magnitude), but these modules are the exception rather than the rule. All practical Gnulib targets use two's complement. * There are no "holes" in integer values: all the bits of an integer contribute to its value in the usual way. * Addresses and sizes behave as if objects reside in a flat address space. In particular: * If two nonoverlapping objects have sizes S and T represented as `size_t' values, then `S + T' cannot overflow. * A pointer P points within an object O if and only if `(char *) &O <= (char *) P && (char *) P < (char *) (&O + 1)'. * If an existing object has size S, and if T is sufficiently small (e.g., 8 KiB), then `S + T' cannot overflow. Overflow in this case would mean that the rest of your program fits into T bytes, which can't happen in realistic flat-address-space hosts. * Objects with all bits zero are treated as 0 or NULL. For example, `memset (A, 0, sizeof A)' initializes an array `A' of pointers to NULL. * Adding zero to a null pointer does not change the pointer. For example, `0 + (char *) NULL == (char *) NULL'. The above assumptions are not required by the C or POSIX standards but hold on all practical porting targets that we're familiar with. If you have a porting target where these assumptions are not true, we'd appreciate hearing of any fixes. We need fixes that do not increase runtime overhead on standard hosts and that are relatively easy to maintain. With the above caveats, Gnulib code should port without problem to new hosts, e.g., hosts conforming to C99 or to recent POSIX standards. Hence Gnulib code should avoid using constructs (e.g., undeclared functions return `int') that do not conform to C99. 1.5 High Quality ================ We develop and maintain a testsuite for Gnulib. The goal is to have a 100% firm interface so that maintainers can feel free to update to the code in git at _any_ time and know that their application will not break. This means that before any change can be committed to the repository, a test suite program must be produced that exposes the bug for regression testing. All experimental work should be done on branches to help promote this. 2 Philosophy ************ Gnulib's design and development philosophy is organized around steady, collaborative, and open development of reusable modules that are suitable for a reasonably wide variety of platforms. 2.1 Benefits of using Gnulib ============================ Gnulib is useful to enhance various aspects of a package: * Portability: With Gnulib, a package maintainer can program against the POSIX and GNU libc APIs and nevertheless expect good portability to platforms that don't implement POSIX. * Maintainability: When a package uses modules from Gnulib instead of code written specifically for that package, the maintainer has less code to maintain. * Security: Gnulib provides functions that are immune against vulnerabilities that plague the uses of the corresponding commonplace functions. For example, `asprintf', `canonicalize_file_name' are not affected by buffer sizing problems that affect `sprintf', `realpath'. `openat' does not have the race conditions that `open' has. Etc. * Reliability: Gnulib provides functions that combine a call to a system function with a check of the result. Examples are `xalloc', `xprintf', `xstrtod', `xgetcwd'. * Structure: Gnulib offers a way to structure code into modules, typically one include file, one source code file, and one autoconf macro for each functionality. Modularity helps maintainability. 2.2 Library vs. Reusable Code ============================= Classical libraries are installed as binary object code. Gnulib is different: It is used as a source code library. Each package that uses Gnulib thus ships with part of the Gnulib source code. The used portion of Gnulib is tailored to the package: A build tool, called `gnulib-tool', is provided that copies a tailored subset of Gnulib into the package. 2.3 Portability and Application Code ==================================== One of the goals of Gnulib is to make portable programming easy, on the basis of the standards relevant for GNU (and Unix). The objective behind that is to avoid a fragmentation of the user community into disjoint user communities according to the operating system, and instead allow synergies between users on different operating systems. Another goal of Gnulib is to provide application code that can be shared between several applications. Some people wonder: "What? glibc doesn't have a function to copy a file?" Indeed, the scope of a system's libc is to implement the relevant standards (ISO C, POSIX) and to provide access functions to the kernel's system calls, and little more. There is no clear borderline between both areas. For example, Gnulib has a facility for generating the name of backup files. While this task is entirely at the application level--no standard specifies an API for it--the nai"ve code has some portability problems because on some platforms the length of file name components is limited to 30 characters or so. Gnulib handles that. Similarly, Gnulib has a facility for executing a command in a subprocess. It is at the same time a portability enhancement (it works on GNU, Unix, and Windows, compared to the classical `fork'/`exec' idiom which is not portable to Windows), as well as an application aid: it takes care of redirecting stdin and/or stdout if desired, and emits an error message if the subprocess failed. 2.4 Target Platforms ==================== Gnulib supports a number of platforms that we call the "reasonable portability targets". This class consists of widespread operating systems, for three years after their last availability, or--for proprietary operating systems--as long as the vendor provides commercial support for it. Already existing Gnulib code for older operating systems is usually left in place for longer than these three years. So it comes that programs that use Gnulib run pretty well also on these older operating systems. Some operating systems are not very widespread, but are Free Software and are actively developed. Such platforms are also supported by Gnulib, if that OS's developers community keeps in touch with the Gnulib developers, by providing bug reports, analyses, or patches. For such platforms, Gnulib supports only the versions of the last year or the last few months, depending on the maturity of said OS project, the number of its users, and how often these users upgrade. Niche operating systems are generally unsupported by Gnulib, unless some of their developers or users contribute support to Gnulib. The degree of support Gnulib guarantees for a platform depends on the amount of testing it gets from volunteers. Platforms on which Gnulib is frequently tested are the best supported. Then come platforms with occasional testing, then platforms which are rarely tested. Usually, we fix bugs when they are reported. Except that some rarely tested platforms are also low priority; bug fixes for these platforms can take longer. As of 2011, the list of supported platforms is the following: * glibc systems. With glibc 2.8 or newer, they are frequently tested. With glibc 2.3 or newer, they are occasionally tested. * Mac OS X. In versions 10.5 and 10.6, it's frequently tested. In version 10.4, it's rarely tested. * FreeBSD 6.0 or newer is occasionally tested. FreeBSD 5.x is rarely tested. * NetBSD 5.0 or newer is occasionally tested. NetBSD 3.0 or newer is rarely tested. * OpenBSD 4.0 or newer is occasionally tested. OpenBSD 3.8 or newer is rarely tested. * AIX 6.1 or newer is occasionally tested. AIX 5.1 or newer is rarely tested. * HP-UX 11.11 or newer is occasionally tested. HP-UX 11.00 is rarely tested. HP-UX 10.20 is rarely tested and low priority. * IRIX 6.5 is occasionally tested. IRIX 5.3 is rarely tested and low priority. * OSF/1 5.1 is occasionally tested. OSF/1 4.0 is rarely tested and low priority. * Solaris 8 and newer are occasionally tested. Solaris 7 is rarely tested. Solaris 2.6 and older are rarely tested and low priority. * Cygwin 1.7.x is frequently tested. Cygwin 1.5.x is occasionally tested. * mingw is frequently tested. But note that some modules are currently unsupported on mingw: `mgetgroups', `getugroups', `idcache', `userspec', `openpty', `login_tty', `forkpty', `pt_chown', `grantpt', `pty', `savewd', `mkancesdirs', `mkdir-p', `euidaccess', `faccessat'. The versions of Windows that are supported are Windows XP and newer. * Native Windows, with MSVC as compiler, is rarely tested and low priority. * mingw in 64-bit mode is not tested and low priority so far. * Interix 6.1 is rarely tested, and requires the `suacomp' library (`http://sourceforge.net/projects/suacomp/') in version 0.6.8 or newer. Interix 3.5 is not tested. * Haiku is rarely tested, BeOS is not tested and low priority. * uClibc on Linux is rarely tested. * QNX is not tested and low priority. Gnulib supports these operating systems only in an unvirtualized environment. When you run an OS inside a virtual machine, you have to be aware that the virtual machine can bring in bugs of its own. For example, floating-point operations on Solaris can behave slightly differently in QEMU than on real hardware. And Haiku's `bash' program misbehaves in VirtualBox 3, whereas it behaves fine in VirtualBox 4. Similarly, running native Windows binaries on GNU/Linux under WINE is rarely tested and low priority: WINE has a set of behaviours and bugs that is slightly different from native Windows. The following platforms are not supported by Gnulib. The cost of supporting them would exceed the benefit because they are rarely used, or poorly documented, or have been supplanted by other platforms, or diverge too much from POSIX, or some combination of these and other factors. Please don't bother sending us patches for them. * Windows 95/98/ME. * DJGPP and EMX (the 32-bit operating systems running in DOS). * MSDOS (the 16-bit operating system). * Windows Mobile, Symbian OS, iOS. 2.5 Modules =========== Gnulib is divided into modules. Every module implements a single facility. Modules can depend on other modules. A module consists of a number of files and a module description. The files are copied by `gnulib-tool' into the package that will use it, usually verbatim, without changes. Source code files (.h, .c files) reside in the `lib/' subdirectory. Autoconf macro files reside in the `m4/' subdirectory. Build scripts reside in the `build-aux/' subdirectory. The module description contains the list of files; `gnulib-tool' copies these files. It contains the module's dependencies; `gnulib-tool' installs them as well. It also contains the autoconf macro invocation (usually a single line or nothing at all); `gnulib-tool' ensures this is invoked from the package's `configure.ac' file. And also a `Makefile.am' snippet; `gnulib-tool' collects these into a `Makefile.am' for the tailored Gnulib part. The module description and include file specification are for documentation purposes; they are combined into `MODULES.html'. The module system serves two purposes: 1. It ensures consistency of the used autoconf macros and `Makefile.am' rules with the source code. For example, source code which uses the `getopt_long' function--this is a common way to implement parsing of command line options in a way that complies with the GNU standards--needs the source code (`lib/getopt.c' and others), the autoconf macro which detects whether the system's libc already has this function (in `m4/getopt.m4'), and a few `Makefile.am' lines that create the substitute `getopt.h' if not. These three pieces belong together. They cannot be used without each other. The module description and `gnulib-tool' ensure that they are copied altogether into the destination package. 2. It allows for scalability. It is well-known since the inception of the MODULA-2 language around 1978 that dissection into modules with dependencies allows for building large sets of code in a maintainable way. The maintainability comes from the facts that: * Every module has a single purpose; you don't worry about other parts of the program while creating, reading or modifying the code of a module. * The code you have to read in order to understand a module is limited to the source of the module and the .h files of the modules listed as dependencies. It is for this reason also that we recommend to put the comments describing the functions exported by a module into its .h file. In other words, the module is the elementary unit of code in Gnulib, comparable to a class in object-oriented languages like Java or C#. The module system is the basis of `gnulib-tool'. When `gnulib-tool' copies a part of Gnulib into a package, it first compiles a module list, starting with the requested modules and adding all the dependencies, and then collects the files, `configure.ac' snippets and `Makefile.am' snippets. 2.6 Various Kinds of Modules ============================ There are modules of various kinds in Gnulib. For a complete list of the modules, see in `MODULES.html'. 2.6.1 Support for ISO C or POSIX functions. ------------------------------------------- When a function is not implemented by a system, the Gnulib module provides an implementation under the same name. Examples are the `snprintf' and `readlink' modules. Similarly, when a function is not correctly implemented by a system, Gnulib provides a replacement. For functions, we use the pattern #if !HAVE_WORKING_FOO # define foo rpl_foo #endif and implement the `foo' function under the name `rpl_foo'. This renaming is needed to avoid conflicts at compile time (in case the system header files declare `foo') and at link/run time (because the code making use of `foo' could end up residing in a shared library, and the executable program using this library could be defining `foo' itself). For header files, such as `stdbool.h' or `stdint.h', we provide the substitute only if the system doesn't provide a correct one. The template of this replacement is distributed in a slightly different name, with `.in' inserted before the `.h' extension, so that on systems which do provide a correct header file the system's one is used. 2.6.2 Enhancements of ISO C or POSIX functions ---------------------------------------------- These are sometimes POSIX functions with GNU extensions also found in glibc--examples: `getopt', `fnmatch'--and often new APIs--for example, for all functions that allocate memory in one way or the other, we have variants which also include the error checking against the out-of-memory condition. 2.6.3 Portable general use facilities ------------------------------------- Examples are a module for copying a file--the portability problems relate to the copying of the file's modification time, access rights, and extended attributes--or a module for extracting the tail component of a file name--here the portability to native Windows requires a different API than the classical POSIX `basename' function. 2.6.4 Reusable application code ------------------------------- Examples are an error reporting function, a module that allows output of numbers with K/M/G suffixes, or cryptographic facilities. 2.6.5 Object oriented classes ----------------------------- Examples are data structures like `list', or abstract output stream classes that work around the fact that an application cannot implement an stdio `FILE' with its logic. Here, while staying in C, we use implementation techniques like tables of function pointers, known from the C++ language or from the Linux kernel. 2.6.6 Interfaces to external libraries -------------------------------------- Examples are the `iconv' module, which interfaces to the `iconv' facility, regardless whether it is contained in libc or in an external `libiconv'. Or the `readline' module, which interfaces to the GNU readline library. 2.6.7 Build / maintenance infrastructure ---------------------------------------- An example is the `maintainer-makefile' module, which provides extra Makefile tags for maintaining a package. 2.7 Collaborative Development ============================= Gnulib is maintained collaboratively. The mailing list is `'. Be warned that some people on the list may be very active at some times and unresponsive at other times. Every module has one or more maintainers. While issues are discussed collaboratively on the list, the maintainer of a module nevertheless has a veto right regarding changes in his module. All patches should be posted the list, regardless whether they are proposed patches or whether they are committed immediately by the maintainer of the particular module. The purpose is not only to inform the other users of the module, but mainly to allow peer review. It is not uncommon that several people contribute comments or spot bugs after a patch was proposed. Conversely, if you are using Gnulib, and a patch is posted that affects one of the modules that your package uses, you have an interest in proofreading the patch. 2.8 Copyright ============= Most modules are under the GPL. Some, mostly modules which can reasonably be used in libraries, are under LGPL. The source files always say "GPL", but the real license specification is in the module description file. If the module description file says "GPL", it means "GPLv3+" (GPLv3 or newer, at the licensee's choice); if it says "LGPL", it means "LGPLv3+" (LGPLv3 or newer, at the licensee's choice). More precisely, the license specification in the module description file applies to the files in `lib/' and `build-aux/'. Different licenses apply to files in special directories: `modules/' Module description files are under this copyright: Copyright (C) 20XX-20YY Free Software Foundation, Inc. Copying and distribution of this file, with or without modification, in any medium, are permitted without royalty provided the copyright notice and this notice are preserved. `m4/' Autoconf macro files are under this copyright: Copyright (C) 20XX-20YY Free Software Foundation, Inc. This file is free software; the Free Software Foundation gives unlimited permission to copy and/or distribute it, with or without modifications, as long as this notice is preserved. `tests/' If a license statement is not present in a test module, the test files are under GPL. Even if the corresponding source module is under LGPL, this is not a problem, since compiled tests are not installed by "make install". `doc/' Documentation files are under this copyright: Copyright (C) 2004-20YY Free Software Foundation, Inc. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled "GNU Free Documentation License". If you want to use some Gnulib modules under LGPL, you can do so by passing the option `--lgpl' to `gnulib-tool'. This will replace the GPL header with an LGPL header while copying the source files to your package. Similarly, if you want some Gnulib modules under LGPLv2+ (Lesser GPL version 2.1 or newer), you can do so by passing the option `--lgpl=2' to `gnulib-tool'. Keep in mind that when you submit patches to files in Gnulib, you should license them under a compatible license. This means that sometimes the contribution will have to be LGPL, if the original file is available under LGPL. You can find out about it by looking for a "License: LGPL" information in the corresponding module description. 2.9 Steady Development ====================== Gnulib modules are continually adapted, to match new practices, to be consistent with newly added modules, or simply as a response to build failure reports. Gnulib is available in two qualities: * There is the newest version of Gnulib from the Git repository. The source tree can also be fetched from a read-only CVS that mirrors the Git repository. * We also make stable releases every two months, at `http://erislabs.net/ianb/projects/gnulib/'. If you are willing to report an occasional regression, we recommend to use the newest version always, except in periods of major changes. Most Gnulib users do this. If you prefer stable releases, please use the newest stable release. 2.10 Openness ============= Gnulib is open in the sense that we gladly accept contributions if they are generally useful, well engineered, and if the contributors have signed the obligatory papers with the FSF. The module system is open in the sense that a package using Gnulib can 1. locally patch or override files in Gnulib, 2. locally add modules that are treated like Gnulib modules by `gnulib-tool'. This is achieved by the `--local-dir' option of `gnulib-tool' (*note Extending Gnulib::). 3 Invoking gnulib-tool ********************** The `gnulib-tool' command is the recommended way to import Gnulib modules. It is possible to borrow Gnulib modules in a package without using `gnulib-tool', relying only on the meta-information stored in the `modules/*' files, but with a growing number of modules this becomes tedious. `gnulib-tool' simplifies the management of source files, `Makefile.am's and `configure.ac' in packages incorporating Gnulib modules. `gnulib-tool' is not installed in a standard directory that is contained in the `PATH' variable. It needs to be run directly in the directory that contains the Gnulib source code. You can do this either by specifying the absolute filename of `gnulib-tool', or you can also use a symbolic link from a place inside your `PATH' to the `gnulib-tool' file of your preferred and most up-to-date Gnulib checkout, like this: $ ln -s $HOME/gnu/src/gnulib.git/gnulib-tool $HOME/bin/gnulib-tool Run `gnulib-tool --help' for information. To get familiar with `gnulib-tool' without affecting your sources, you can also try some commands with the option `--dry-run'; then `gnulib-tool' will only report which actions it would perform in a real run without changing anything. 3.1 Finding modules =================== There are three ways of finding the names of Gnulib modules that you can use in your package: * You have the complete module list, sorted according to categories, in `http://www.gnu.org/software/gnulib/MODULES.html'. * If you are looking for a particular POSIX header or function replacement, look in the chapters *note Header File Substitutes:: and *note Function Substitutes::. For headers and functions that are provided by Glibc but not standardized by POSIX, look in the chapters *note Glibc Header File Substitutes:: and *note Glibc Function Substitutes::. * If you have already found the source file in Gnulib and are looking for the module that contains this source file, you can use the command `gnulib-tool --find FILENAME'. 3.2 Initial import ================== Gnulib assumes that your project uses Autoconf. When using Gnulib, you will need to have Autoconf and Automake among your build tools. Note that while the use of Automake in your project's top level directory is an easy way to fulfil the Makefile conventions of the GNU coding standards, Gnulib does not require it. But when you use Gnulib, Automake will be used at least in a subdirectory of your project. Invoking `gnulib-tool --import' will copy source files, create a `Makefile.am' to build them, generate a file `gnulib-comp.m4' with Autoconf M4 macro declarations used by `configure.ac', and generate a file `gnulib-cache.m4' containing the cached specification of how Gnulib is used. Our example will be a library that uses Autoconf, Automake and Libtool. It calls `strdup', and you wish to use gnulib to make the package portable to C89 and C99 (which don't have `strdup'). ~/src/libfoo$ gnulib-tool --import strdup Module list with included dependencies: absolute-header extensions strdup string File list: lib/dummy.c lib/strdup.c lib/string.in.h m4/absolute-header.m4 m4/extensions.m4 m4/gnulib-common.m4 m4/strdup.m4 m4/string_h.m4 Creating directory ./lib Creating directory ./m4 Copying file lib/dummy.c Copying file lib/strdup.c Copying file lib/string.in.h Copying file m4/absolute-header.m4 Copying file m4/extensions.m4 Copying file m4/gnulib-common.m4 Copying file m4/gnulib-tool.m4 Copying file m4/strdup.m4 Copying file m4/string_h.m4 Creating lib/Makefile.am Creating m4/gnulib-cache.m4 Creating m4/gnulib-comp.m4 Finished. You may need to add #include directives for the following .h files. #include Don't forget to - add "lib/Makefile" to AC_CONFIG_FILES in ./configure.ac, - mention "lib" in SUBDIRS in Makefile.am, - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am, - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC, - invoke gl_INIT in ./configure.ac. ~/src/libfoo$ By default, the source code is copied into `lib/' and the M4 macros in `m4/'. You can override these paths by using `--source-base=DIRECTORY' and `--m4-base=DIRECTORY'. Some modules also provide other files necessary for building. These files are copied into the directory specified by `AC_CONFIG_AUX_DIR' in `configure.ac' or by the `--aux-dir=DIRECTORY' option. If neither is specified, the current directory is assumed. `gnulib-tool' can make symbolic links instead of copying the source files. The option to specify for this is `--symlink', or `-s' for short. This can be useful to save a few kilobytes of disk space. But it is likely to introduce bugs when `gnulib' is updated; it is more reliable to use `gnulib-tool --update' (see below) to update to newer versions of `gnulib'. Furthermore it requires extra effort to create self-contained tarballs, and it may disturb some mechanism the maintainer applies to the sources. For these reasons, this option is generally discouraged. `gnulib-tool' will overwrite any pre-existing files, in particular `Makefile.am'. It is also possible to separate the generated `Makefile.am' content (for building the gnulib library) into a separate file, say `gnulib.mk', that can be included by your handwritten `Makefile.am', but this is a more advanced use of `gnulib-tool'. Consequently, it is a good idea to choose directories that are not already used by your projects, to separate gnulib imported files from your own files. This approach is also useful if you want to avoid conflicts between other tools (e.g., `gettextize' that also copy M4 files into your package. Simon Josefsson successfully uses a source base of `gl/', and a M4 base of `gl/m4/', in several packages. After the `--import' option on the command line comes the list of Gnulib modules that you want to incorporate in your package. The names of the modules coincide with the filenames in Gnulib's `modules/' directory. Some Gnulib modules depend on other Gnulib modules. `gnulib-tool' will automatically add the needed modules as well; you need not list them explicitly. `gnulib-tool' will also memorize which dependent modules it has added, so that when someday a dependency is dropped, the implicitly added module is dropped as well (unless you have explicitly requested that module). If you want to cut a dependency, i.e., not add a module although one of your requested modules depends on it, you may use the option `--avoid=MODULE' to do so. Multiple uses of this option are possible. Of course, you will then need to implement the same interface as the removed module. A few manual steps are required to finish the initial import. `gnulib-tool' printed a summary of these steps. First, you must ensure Autoconf can find the macro definitions in `gnulib-comp.m4'. Use the `ACLOCAL_AMFLAGS' specifier in your top-level `Makefile.am' file, as in: ACLOCAL_AMFLAGS = -I m4 You are now ready to call the M4 macros in `gnulib-comp.m4' from `configure.ac'. The macro `gl_EARLY' must be called as soon as possible after verifying that the C compiler is working. Typically, this is immediately after `AC_PROG_CC', as in: ... AC_PROG_CC gl_EARLY ... If you are using `AC_PROG_CC_STDC', the macro `gl_EARLY' must be called after it, like this: ... AC_PROG_CC AC_PROG_CC_STDC gl_EARLY ... The core part of the gnulib checks are done by the macro `gl_INIT'. Place it further down in the file, typically where you normally check for header files or functions. It must come after other checks which may affect the compiler invocation, such as `AC_MINIX'. For example: ... # For gnulib. gl_INIT ... `gl_INIT' will in turn call the macros related with the gnulib functions, be it specific gnulib macros, like `gl_FUNC_ALLOCA' or autoconf or automake macros like `AC_FUNC_ALLOCA' or `AM_FUNC_GETLINE'. So there is no need to call those macros yourself when you use the corresponding gnulib modules. You must also make sure that the gnulib library is built. Add the `Makefile' in the gnulib source base directory to `AC_CONFIG_FILES', as in: AC_CONFIG_FILES(... lib/Makefile ...) You must also make sure that `make' will recurse into the gnulib directory. To achieve this, add the gnulib source base directory to a `SUBDIRS' Makefile.am statement, as in: SUBDIRS = lib or if you, more likely, already have a few entries in `SUBDIRS', you can add something like: SUBDIRS += lib Finally, you have to add compiler and linker flags in the appropriate source directories, so that you can make use of the gnulib library. Since some modules (`getopt', for example) may copy files into the build directory, `top_builddir/lib' is needed as well as `top_srcdir/lib'. For example: ... AM_CPPFLAGS = -I$(top_builddir)/lib -I$(top_srcdir)/lib ... LDADD = lib/libgnu.a ... Don't forget to `#include' the various header files. In this example, you would need to make sure that `#include ' is evaluated when compiling all source code files, that want to make use of `strdup'. In the usual case where Autoconf is creating a `config.h' file, you should include `config.h' first, before any other include file. That way, for example, if `config.h' defines `restrict' to be the empty string on a pre-C99 host, or a macro like `_FILE_OFFSET_BITS' that affects the layout of data structures, the definition is consistent for all include files. Also, on some platforms macros like `_FILE_OFFSET_BITS' and `_GNU_SOURCE' may be ineffective, or may have only a limited effect, if defined after the first system header file is included. Finally, note that you cannot use `AC_LIBOBJ' or `AC_REPLACE_FUNCS' in your `configure.ac' and expect the resulting object files to be automatically added to `lib/libgnu.a'. This is because your `AC_LIBOBJ' and `AC_REPLACE_FUNCS' invocations from `configure.ac' augment a variable `@LIBOBJS@' (and/or `@LTLIBOBJS@' if using Libtool), whereas `lib/libgnu.a' is built from the contents of a different variable, usually `@gl_LIBOBJS@' (or `@gl_LTLIBOBJS@' if using Libtool). 3.3 Modified imports ==================== You can at any moment decide to use Gnulib differently than the last time. There are two ways to change how Gnulib is used. Which one you'll use, depends on where you keep track of options and module names that you pass to `gnulib-tool'. * If you store the options and module names in a file under your own control, such as `autogen.sh', `bootstrap', `bootstrap.conf', or similar, simply invoke `gnulib-tool' again, with modified options and more or fewer module names. * `gnulib-tool' remembers which modules were used last time. If you want to rely on `gnulib-tool''s own memory of the last used options and module names, you can use the commands `gnulib-tool --add-import' and `gnulib-tool --remove-import'. So, if you only want to use more Gnulib modules, simply invoke `gnulib-tool --add-import NEW-MODULES'. The list of modules that you pass after `--add-import' is _added_ to the previous list of modules. Similarly, if you want to use fewer Gnulib modules, simply invoke `gnulib-tool --remove-import UNNEEDED-MODULES'. The list of modules that you pass after `--remove-import' is _removed_ from the previous list of modules. Note that if a module is then still needed as dependency of other modules, it will be used nevertheless. If you want to _really_ not use a module any more, regardless of whether other modules may need it, you need to use the `--avoid' option. For other changes, such as different choices of `--lib', `--source-base' or `--aux-dir', the normal way is to modify manually the file `gnulib-cache.m4' in the M4 macros directory, then launch `gnulib-tool --add-import'. The only change for which this doesn't work is a change of the `--m4-base' directory. Because, when you pass a different value of `--m4-base', `gnulib-tool' will not find the previous `gnulib-cache.m4' file any more. A possible solution is to manually copy the `gnulib-cache.m4' into the new M4 macro directory. In the `gnulib-cache.m4' file, the macros have the following meaning: `gl_MODULES' The argument is a space separated list of the requested modules, not including dependencies. `gl_AVOID' The argument is a space separated list of modules that should not be used, even if they occur as dependencies. Corresponds to the `--avoid' command line argument. `gl_SOURCE_BASE' The argument is the relative file name of the directory containing the gnulib source files (mostly *.c and *.h files). Corresponds to the `--source-base' command line argument. `gl_M4_BASE' The argument is the relative file name of the directory containing the gnulib M4 macros (*.m4 files). Corresponds to the `--m4-base' command line argument. `gl_TESTS_BASE' The argument is the relative file name of the directory containing the gnulib unit test files. Corresponds to the `--tests-base' command line argument. `gl_LIB' The argument is the name of the library to be created. Corresponds to the `--lib' command line argument. `gl_LGPL' The presence of this macro without arguments corresponds to the `--lgpl' command line argument. The presence of this macro with an argument (whose value must be 2 or 3) corresponds to the `--lgpl=ARG' command line argument. `gl_LIBTOOL' The presence of this macro corresponds to the `--libtool' command line argument and to the absence of the `--no-libtool' command line argument. It takes no arguments. `gl_MACRO_PREFIX' The argument is the prefix to use for macros in the `gnulib-comp.m4' file. Corresponds to the `--macro-prefix' command line argument. 3.4 Simple update ================= When you want to update to a more recent version of Gnulib, without changing the list of modules or other parameters, a simple call does it: $ gnulib-tool --add-import This will create, update or remove files, as needed. Note: From time to time, changes are made in Gnulib that are not backward compatible. When updating to a more recent Gnulib, you should consult Gnulib's `NEWS' file to check whether the incompatible changes affect your project. 3.5 Changing your sources for use with Gnulib ============================================= Gnulib contains some header file overrides. This means that when building on systems with deficient header files in `/usr/include/', it may create files named `string.h', `stdlib.h', `stdint.h' or similar in the build directory. In the other source directories of your package you will usually pass `-I' options to the compiler, so that these Gnulib substitutes are visible and take precedence over the files in `/usr/include/'. These Gnulib substitute header files rely on `' being already included. Furthermore `' must be the first include in every compilation unit. This means that to _all your source files_ and likely also to _all your tests source files_ you need to add an `#include ' at the top. Which source files are affected? Exactly those whose compilation includes a `-I' option that refers to the Gnulib library directory. This is annoying, but inevitable: On many systems, `' is used to set system dependent flags (such as `_GNU_SOURCE' on GNU systems), and these flags have no effect after any system header file has been included. 3.6 Caveat: `gettextize' and `autopoint' users ============================================== The programs `gettextize' and `autopoint', part of GNU `gettext', import or update the internationalization infrastructure. Some of this infrastructure, namely ca. 20 autoconf macro files and the `config.rpath' file, is also contained in Gnulib and may be imported by `gnulib-tool'. The use of `gettextize' or `autopoint' will therefore overwrite some of the files that `gnulib-tool' has imported, and vice versa. Avoiding to use `gettextize' (manually, as package maintainer) or `autopoint' (as part of a script like `autoreconf' or `autogen.sh') is not the solution: These programs also import the infrastructure in the `po/' and optionally in the `intl/' directory. The copies of the conflicting files in Gnulib are more up-to-date than the copies brought in by `gettextize' and `autopoint'. When a new `gettext' release is made, the copies of the files in Gnulib will be updated immediately. The choice of which version of gettext to require depends on the needs of your package. For a package that wants to comply to GNU Coding Standards, the steps are: 1. When you run `gettextize', always use the `gettextize' from the matching GNU gettext release. For the most recent Gnulib checkout, this is the newest release found on `http://ftp.gnu.org/gnu/gettext/'. For an older Gnulib snapshot, it is the release that was the most recent release at the time the Gnulib snapshot was taken. 2. After running `gettextize', invoke `gnulib-tool' and import the `gettext' module. Also, copy the latest version of gnulib's `build-aux/po/Makefile.in.in' to your `po/' directory (this is done for you if you use gnulib's `bootstrap' script). 3. If you get an error message like `*** error: gettext infrastructure mismatch: using a Makefile.in.in from gettext version ... but the autoconf macros are from gettext version ...', it means that a new GNU gettext release was made, and its autoconf macros were integrated into Gnulib and now mismatch the `po/' infrastructure. In this case, fetch and install the new GNU gettext release and run `gettextize' followed by `gnulib-tool'. On the other hand, if your package is not as concerned with compliance to the latest standards, but instead favors development on stable environments, the steps are: 1. Determine the oldest version of `gettext' that you intend to support during development (at this time, gnulib recommends going no older than version 0.17). Run `autopoint' (not `gettextize') to copy infrastructure into place (newer versions of gettext will install the older infrastructure that you requested). 2. Invoke `gnulib-tool', and import the `gettext-h' module. Regardless of which approach you used to get the infrastructure in place, the following steps must then be used to preserve that infrastructure (gnulib's `bootstrap' script follows these rules): 1. When a script of yours run `autopoint', invoke `gnulib-tool' afterwards. 2. When you invoke `autoreconf' after `gnulib-tool', make sure to not invoke `autopoint' a second time, by setting the `AUTOPOINT' environment variable, like this: $ env AUTOPOINT=true autoreconf --install 3.7 Handling Gnulib's own message translations ============================================== Gnulib provides some functions that emit translatable messages using GNU `gettext'. The `gnulib' domain at the Translation Project (http://translationproject.org/) collects translations of these messages, which you should incorporate into your own programs. There are two basic ways to achieve this. The first, and older, method is to list all the source files you use from Gnulib in your own `po/POTFILES.in' file. This will cause all the relevant translatable strings to be included in your POT file. When you send this POT file to the Translation Project, translators will normally fill in the translations of the Gnulib strings from their "translation memory", and send you back updated PO files. However, this process is error-prone: you might forget to list some source files, or the translator might not be using a translation memory and provide a different translation than another translator, or the translation might not be kept in sync between Gnulib and your package. It is also slow and causes substantial extra work, because a human translator must be in the loop for each language and you will need to incorporate their work on request. For these reasons, a new method was designed and is now recommended. If you pass the `--po-base=DIRECTORY' and `--po-domain=DOMAIN' options to `gnulib-tool', then `gnulib-tool' will create a separate directory with its own `POTFILES.in', and fetch current translations directly from the Translation Project (using `rsync' or `wget', whichever is available). The POT file in this directory will be called `DOMAIN-gnulib.pot', depending on the DOMAIN you gave to the `--po-domain' option (typically the same as the package name). This causes these translations to reside in a separate message domain, so that they do not clash either with the translations for the main part of your package nor with those of other packages on the system that use possibly different versions of Gnulib. When you use these options, the functions in Gnulib are built in such a way that they will always use this domain regardless of the default domain set by `textdomain'. In order to use this method, you must--in each program that might use Gnulib code--add an extra line to the part of the program that initializes locale-dependent behavior. Where you would normally write something like: setlocale (LC_ALL, ""); bindtextdomain (PACKAGE, LOCALEDIR); textdomain (PACKAGE); you should add an additional `bindtextdomain' call to inform gettext of where the MO files for the extra message domain may be found: bindtextdomain (PACKAGE "-gnulib", LOCALEDIR); (This example assumes that the DOMAIN that you specified to `gnulib-tool' is the same as the value of the `PACKAGE' preprocessor macro.) Since you do not change the `textdomain' call, the default message domain for your program remains the same and your own use of `gettext' functions will not be affected. 3.8 Issues with Version Control Systems ======================================= If a project stores its source files in a version control system (VCS), such as CVS, Subversion, or Git, one needs to decide which files to commit. In principle, all files created by `gnulib-tool', except `gnulib-cache.m4', can be treated like generated source files, like for example a `parser.c' file generated from `parser.y'. Alternatively, they can be considered source files and updated manually. Here are the three different approaches in common use. Each has its place, and you should use whichever best suits your particular project and development methods. 1. In projects which commit all source files, whether generated or not, into their VCS, the `gnulib-tool' generated files should all be committed. In this case, you should pass the option `--no-vc-files' to `gnulib-tool', which avoids alteration of VCS-related files such as `.cvsignore'. Gnulib also contains files generated by `make' (and removed by `make clean'), using information determined by `configure'. For a Gnulib source file of the form `lib/foo.in.h', the corresponding `lib/foo.h' is such a `make'-generated file. These should _not_ be checked into the VCS, but instead added to `.cvsignore' or equivalent. 2. In projects which customarily omit from their VCS all files that are generated from other source files, none of these files and directories are added into the VCS. As described in *note Modified imports::, there are two ways to keep track of options and module names that are passed to `gnulib-tool'. The command for restoring the omitted files depends on it: * If they are stored in a file other than `gnulib-cache.m4', such as `autogen.sh', `bootstrap', `bootstrap.conf', or similar, the restoration command is the entire `gnulib-tool ... --import ...' invocation with all options and module names. * If the project relies on `gnulib-tool''s memory of the last used options and module names, then the file `gnulib-cache.m4' in the M4 macros directory must be added to the VCS, and the restoration command is: $ gnulib-tool --update The `--update' option operates much like the `--add-import' option, but it does not offer the possibility to change the way Gnulib is used. Also it does not report in the ChangeLogs the files that it had to add because they were missing. Gnulib includes the file `build-aux/bootstrap' to aid a developer in using this setup. Furthermore, in projects that use git for version control, it is possible to use a git submodule containing the precise commit of the gnulib repository, so that each developer running `bootstrap' will get the same version of all gnulib-provided files. The location of the submodule can be chosen to fit the package's needs; here's how to initially create the submodule in the directory `.gnulib': $ dir=.gnulib $ git submodule add -- git://git.sv.gnu.org/gnulib.git $dir $ git config alias.syncsub "submodule foreach git pull origin master" Thereafter, `bootstrap' can run this command to update the submodule to the recorded checkout level: git submodule update --init $dir and a developer can use this sequence to update to a newer version of gnulib: $ git syncsub $ git add $dir $ ./bootstrap 3. Some projects take a "middle road": they do commit Gnulib source files as in the first approach, but they do not commit other derived files, such as a `Makefile.in' generated by Automake. This increases the size and complexity of the repository, but can help occasional contributors by not requiring them to have a full Gnulib checkout to do a build, and all developers by ensuring that all developers are working with the same version of Gnulib in the repository. It also supports multiple Gnulib instances within a project. It remains important not to commit the `make'-generated files, as described above. 3.9 Bundling the unit tests of the Gnulib modules ================================================= You can bundle the unit tests of the Gnulib modules together with your package, through the `--with-tests' option. Together with `--with-tests', you also specify the directory for these tests through the `--tests-base' option. Of course, you need to add this directory to the `SUBDIRS' variable in the `Makefile.am' of the parent directory. The advantage of having the unit tests bundled is that when your program has a problem on a particular platform, running the unit tests may help determine quickly if the problem is on Gnulib's side or on your package's side. Also, it helps verifying Gnulib's portability, of course. The unit tests will be compiled and run when the user runs `make check'. When the user runs only `make', the unit tests will not be compiled. In the `SUBDIRS' variable, it is useful to put the Gnulib tests directory after the directory containing the other tests, not before: SUBDIRS = gnulib-lib src man tests gnulib-tests This will ensure that on platforms where there are test failures in either directory, users will see and report the failures from the tests of your program. Note: In packages which use more than one invocation of `gnulib-tool' in the scope of the same `configure.ac', you cannot use `--with-tests'. You will have to use a separate `configure.ac' in this case. 3.10 Avoiding unnecessary checks and compilations ================================================= In some cases, a module is needed by another module only on specific platforms. But when a module is present, its autoconf checks are always executed, and its `Makefile.am' additions are always enabled. So it can happen that some autoconf checks are executed and some source files are compiled, although no other module needs them on this particular platform, just _in case_ some other module would need them. The option `--conditional-dependencies' enables an optimization of configure checks and `Makefile.am' snippets that avoids this. With this option, whether a module is considered "present" is no longer decided when `gnulib-tool' is invoked, but later, when `configure' is run. This applies to modules that were added as dependencies while `gnulib-tool' was run; modules that were passed on the command line explicitly are always "present". For example, the `timegm' module needs, on platforms where the system's `timegm' function is missing or buggy, a replacement that is based on a function `mktime_internal'. The module `mktime-internal' that provides this function provides it on all platforms. So, by default, the file `mktime-internal.c' will be compiled on all platforms, even on glibc and BSD systems which have a working `timegm' function. When the option `--conditional-dependencies' is given, on the other hand, and if `mktime-internal' was not explicitly required on the command line, the file `mktime-internal.c' will only be compiled on the platforms where the `timegm' needs them. Conditional dependencies are specified in the module description by putting the condition on the same line as the dependent module, enclosed in brackets. The condition is a boolean shell expression that can assume that the `configure.ac' snippet from the module description has already been executed. In the example above, the dependency from `timegm' to `mktime-internal' is written like this: Depends-on: ... mktime-internal [test $HAVE_TIMEGM = 0 || test $REPLACE_TIMEGM = 1] ... Note: The option `--conditional-dependencies' cannot be used together with the option `--with-tests'. It also cannot be used when a package uses `gnulib-tool' for several subdirectories, with different values of `--source-base', in the scope of a single `configure.ac' file. 4 Writing modules ***************** This chapter explains how to write modules of your own, either to extend Gnulib for your own package (*note Extending Gnulib::), or for inclusion in gnulib proper. The guidelines in this chapter do not necessarily need to be followed for using `gnulib-tool'. They merely represent a set of good practices. Following them will result in a good structure of your modules and in consistency with gnulib. 4.1 Source code files ===================== Every API (C functions or variables) provided should be declared in a header file (.h file) and implemented in one or more implementation files (.c files). The separation has the effect that users of your module need to read only the contents of the .h file and the module description in order to understand what the module is about and how to use it--not the entire implementation. Furthermore, users of your module don't need to repeat the declarations of the functions in their code, and are likely to receive notification through compiler errors if you make incompatible changes to the API (like, adding a parameter or changing the return type of a function). 4.2 Header files ================ The .h file should declare the C functions and variables that the module provides. The .h file should be stand-alone. That is, it does not require other .h files to be included before. Rather, it includes all necessary .h files by itself. It is a tradition to use CPP tricks to avoid parsing the same header file more than once, which might cause warnings. The trick is to wrap the content of the header file (say, `foo.h') in a block, as in: #ifndef FOO_H # define FOO_H ... body of header file goes here ... #endif /* FOO_H */ Whether to use `FOO_H' or `_FOO_H' is a matter of taste and style. The C89 and C99 standards reserve all identifiers that begin with an underscore and either an uppercase letter or another underscore, for any use. Thus, in theory, an application might not safely assume that `_FOO_H' has not already been defined by a library. On the other hand, using `FOO_H' will likely lead the higher risk of collisions with other symbols (e.g., `KEY_H', `XK_H', `BPF_H', which are CPP macro constants, or `COFF_LONG_H', which is a CPP macro function). Your preference may depend on whether you consider the header file under discussion as part of the application (which has its own namespace for CPP symbols) or a supporting library (that shouldn't interfere with the application's CPP symbol namespace). Adapting C header files for use in C++ applications can use another CPP trick, as in: # ifdef __cplusplus extern "C" { # endif ... body of header file goes here ... # ifdef __cplusplus } # endif The idea here is that `__cplusplus' is defined only by C++ implementations, which will wrap the header file in an `extern "C"' block. Again, whether to use this trick is a matter of taste and style. While the above can be seen as harmless, it could be argued that the header file is written in C, and any C++ application using it should explicitly use the `extern "C"' block itself. Your preference might depend on whether you consider the API exported by your header file as something available for C programs only, or for C and C++ programs alike. Note that putting a `#include' in an `extern "C" { ... }' block yields a syntax error in C++ mode on some platforms (e.g., glibc systems with g++ v3.3 to v4.2, AIX, OSF/1, IRIX). For this reason, it is recommended to place the `#include' before the `extern "C"' block. 4.3 Implementation files ======================== The .c file or files implement the functions and variables declared in the .h file. Include ordering ---------------- Every implementation file must start with `#include '. This is necessary for activating the preprocessor macros that are defined on behalf of the Autoconf macros. Some of these preprocessor macros, such as `_GNU_SOURCE', would have no effect if defined after a system header file has already been included. Then comes the `#include "..."' specifying the header file that is being implemented. Putting this right after `#include ' has the effect that it verifies that the header file is self-contained. Then come the system and application headers. It is customary to put all the system headers before all application headers, so as to minimize the risk that a preprocessor macro defined in an application header confuses the system headers on some platforms. In summary: * First comes #include . * Second comes the #include "..." specifying the module being implemented. * Then come all the #include <...> of system or system-replacement headers, in arbitrary order. * Then come all the #include "..." of gnulib and application headers, in arbitrary order. 4.4 Specification ================= The specification of a function should answer at least the following questions: * What is the purpose of the function? * What are the arguments? * What is the return value? * What happens in case of failure? (Exit? A specific return value? Errno set?) * Memory allocation policy: If pointers to memory are returned, are they freshly allocated and supposed to be freed by the caller? Where to put the specification describing exported functions? Three practices are used in gnulib: * The specification can be as comments in the header file, just above the function declaration. * The specification can be as comments in the implementation file, just above the function definition. * The specification can be in texinfo format, so that it gets included in the gnulib manual. In any case, the specification should appear in just one place, unless you can ensure that the multiple copies will always remain identical. The advantage of putting it in the header file is that the user only has to read the include file normally never needs to peek into the implementation file(s). The advantage of putting it in the implementation file is that when reviewing or changing the implementation, you have both elements side by side. The advantage of texinfo formatted documentation is that it is easily published in HTML or Info format. Currently (as of 2010), half of gnulib uses the first practice, nearly half of gnulib uses the second practice, and a small minority uses the texinfo practice. 4.5 Module description ====================== For the module description, you can start from an existing module's description, or from a blank one: `module/TEMPLATE' for a normal module, or `module/TEMPLATE-TESTS' for a unit test module. Some more fields are possible but rarely used. Use `module/TEMPLATE-EXTENDED' if you want to use one of them. Module descriptions have the following fields. Absent fields are equivalent to fields with empty contents. Description This field should contain a concise description of the module's functionality. One sentence is enough. For example, if it defines a single function `frob', the description can be `frob() function: frobnication.' Gnulib's documentation generator will automatically convert the first part to a hyperlink when it has this form. Status This field is either empty/absent, or contains the word `obsolete'. In the latter case, `gnulib-tool' will, unless the option `--with-obsolete' is given, omit it when it used as a dependency. It is good practice to also notify the user about an obsolete module. This is done by putting into the `Notice' section (see below) text like `This module is obsolete.' Notice This field contains text that `gnulib-tool' will show to the user when the module is used. This can be a status indicator like `This module is obsolete.' or additional advice. Do not abuse this field. Applicability This field is either empty/absent, or contains the word `all'. It describes to which `Makefile.am' the module is applied. By default, a normal module is applied to `SOURCE_BASE/Makefile.am' (normally `lib/Makefile.am'), whereas a module ending in `-tests' is applied to `TESTS_BASE/Makefile.am' (normally `tests/Makefile.am'). If this field is `all', it is applied to both `Makefile.am's. This is useful for modules which provide Makefile.am macros rather than compiled source code. Files This field contains a newline separated list of the files that are part of the module. `gnulib-tool' copies these files into the package that uses the module. This list is typically ordered by importance: First comes the header file, then the implementation files, then other files. It is possible to have the same file mentioned in multiple modules. That is, if the maintainers of that module agree on the purpose and future of said file. Depends-on This field contains a newline separated list of the modules that are required for the proper working of this module. `gnulib-tool' includes each required module automatically, unless it is specified with option `--avoid' or it is marked as obsolete and the option `--with-obsolete' is not given. A test modules `foo-tests' implicitly depends on the corresponding non-test module `foo'. `foo' implicitly depends on `foo-tests' if the latter exists and if the option `--with-tests' has been given. Tests modules can depend on non-tests modules. Non-tests modules should not depend on tests modules. (Recall that tests modules are built in a separate directory.) Each listed required module may be declared a conditional dependency. This is indicated by placing the condition for the dependency on the same line, enclosed in brackets, after the name of the required module. The condition is a shell expression that is run after the module's `configure.ac' statements. For example: strtoull [test $ac_cv_func_strtoumax = no] Lines starting with `#' are recognized as comments and are ignored. configure.ac-early This field contains `configure.ac' stuff (Autoconf macro invocations and shell statements) that are logically placed early in the `configure.ac' file: right after the `AC_PROG_CC' invocation. This section is adequate for statements that modify `CPPFLAGS', as these can affect the results of other Autoconf macros. configure.ac This field contains `configure.ac' stuff (Autoconf macro invocations and shell statements). It is forbidden to add items to the `CPPFLAGS' variable here, other than temporarily, as these could affect the results of other Autoconf macros. We avoid adding items to the `LIBS' variable, other than temporarily. Instead, the module can export an Autoconf-substituted variable that contains link options. The user of the module can then decide to which executables to apply which link options. Recall that a package can build executables of different kinds and purposes; having all executables link against all libraries is inappropriate. If the statements in this section grow larger than a couple of lines, we recommend moving them to a `.m4' file of their own. Makefile.am This field contains `Makefile.am' statements. Variables like `lib_SOURCES' are transformed to match the name of the library being built in that directory. For example, `lib_SOURCES' may become `libgnu_a_SOURCES' (for a plain library) or `libgnu_la_SOURCES' (for a libtool library). Therefore, the normal way of having an implementation file `lib/foo.c' compiled unconditionally is to write lib_SOURCES += foo.c Include This field contains the preprocessor statements that users of the module need to add to their source code files. Typically it's a single include statement. A shorthand is allowed: You don't need to write the word "#include", just the name of the include file in the way it will appear in an include statement. Example: "foo.h" Link This field contains the set of libraries that are needed when linking libraries or executables that use this module. Often this will be written as a reference to a Makefile variable. Please write them one per line, so that `gnulib-tool' can remove duplicates when presenting a summary to the user. Example: $(POW_LIBM) $(LTLIBICONV) when linking with libtool, $(LIBICONV) otherwise License This field specifies the license that governs the source code parts of this module. See *note Copyright:: for details. Maintainer This field specifies the persons who have a definitive say about proposed changes to this module. You don't need to mention email addresses here: they can be inferred from the `ChangeLog' file. Please put at least one person here. We don't like unmaintained modules. 4.6 Autoconf macros =================== For a module `foo', an Autoconf macro file `m4/foo.m4' is typically created when the Autoconf macro invocations for the module are longer than one or two lines. The name of the main entry point into this Autoconf macro file is typically `gl_FOO'. For modules outside Gnulib that are not likely to be moved into Gnulib, please use a prefix specific to your package: `gt_' for GNU gettext, `cu_' for GNU coreutils, etc. For modules that define a function `foo', the entry point is called `gl_FUNC_FOO' instead of `gl_FOO'. For modules that provide a header file with multiple functions, say `foo.h', the entry point is called `gl_FOO_H' or `gl_HEADER_FOO_H'. This convention is useful because sometimes a header and a function name coincide (for example, `fcntl' and `fcntl.h'). For modules that provide a replacement, it is useful to split the Autoconf macro into two macro definitions: one that detects whether the replacement is needed and requests the replacement using `AC_LIBOBJ' (this is the entry point, say `gl_FUNC_FOO'), and one that arranges for the macros needed by the replacement code `lib/foo.c' (typically called `gl_PREREQ_FOO'). The reason of this separation is 1. to make it easy to update the Autoconf macros when you have modified the source code file: after changing `lib/foo.c', all you have to review is the `Depends-on' section of the module description and the `gl_PREREQ_FOO' macro in the Autoconf macro file. 2. The Autoconf macros are often large enough that splitting them eases maintenance. 4.7 Unit test modules ===================== A unit test that is a simple C program usually has a module description as simple as this: Files: tests/test-foo.c tests/macros.h Depends-on: configure.ac: Makefile.am: TESTS += test-foo check_PROGRAMS += test-foo The test program `tests/test-foo.c' often has the following structure: * First comes the obligatory `#include '. * Second comes the include of the header file that declares the API being tested. Including it here verifies that said header file is self-contained. * Then come other includes. In particular, the file `macros.h' is often used here. It contains a convenient `ASSERT' macro. The body of the test, then, contains many `ASSERT' invocations. When a test fails, the `ASSERT' macro prints the line number of the failing statement, thus giving you, the developer, an idea of which part of the test failed, even when you don't have access to the machine where the test failed and the reporting user cannot run a debugger. Sometimes it is convenient to write part of the test as a shell script. (For example, in areas related to process control or interprocess communication, or when different locales should be tried.) In these cases, the typical module description is like this: Files: tests/test-foo.sh tests/test-foo.c tests/macros.h Depends-on: configure.ac: Makefile.am: TESTS += test-foo.sh TESTS_ENVIRONMENT += FOO_BAR='@FOO_BAR@' check_PROGRAMS += test-foo Here, the `TESTS_ENVIRONMENT' variable can be used to pass values determined by `configure' or by the `Makefile' to the shell script, as environment variables. The values of `EXEEXT' and of `srcdir', from Autoconf and Automake, are already provided as environment variables, through an initial value of `TESTS_ENVIRONMENT' that `gnulib-tool' puts in place. Regardless of the specific form of the unit test, the following guidelines should be respected: * A test indicates success by exiting with exit code 0. It should normally not produce output in this case. (Output to temporary files that are cleaned up at the end of the test are possible, of course.) * A test indicates failure by exiting with an exit code different from 0 and 77, typically 1. It is useful to print a message about the failure in this case. The `ASSERT' macro already does so. * A test indicates "skip", that is, that most of its interesting functionality could not be performed, through a return code of 77. A test should also print a message to stdout or stderr about the reason for skipping. For example: fputs ("Skipping test: multithreading not enabled\n", stderr); return 77; Such a message helps detecting bugs in the autoconf macros: A simple message `SKIP: test-foo' does not sufficiently catch the attention of the user. 4.8 Incompatible changes ======================== Incompatible changes to Gnulib modules should be mentioned in Gnulib's `NEWS' file. Incompatible changes here mean that existing source code may not compile or work any more. We don't mean changes in the binary interface (ABI), since 1. Gnulib code is used in source-code form. 2. The user who distributes libraries that contain Gnulib code is supposed to bump the version number in the way described in the Libtool documentation before every release. 5 Extending Gnulib ****************** Gnulib modules are intended to be suitable for widespread use. Most problems with Gnulib can and should be fixed in a generic way, so that all of Gnulib's users can benefit from the change. But occasionally a problem arises that is difficult or undesirable to fix generically, or a project that uses Gnulib may need to work around an issue before the Gnulib maintainers commit a final fix. Maintainers may also want to add their own pools of modules to projects as Gnulib "staging areas." The obvious way to make local changes to Gnulib modules is to use `gnulib-tool' to check out pristine modules, then to modify the results in-place. This works well enough for short-lived experiments. It is harder to keep modified versions of Gnulib modules for a long time, even though Git (or another distributed version control systems) can help out a lot with this during the development process. Git, however, doesn't address the distribution issue. When a package "foobar" needs a modified version of, say, `stdint.in.h', it either has to put a comment into `foobar/autogen.sh' saying "Attention! This doesn't work with a pristine Gnulib, you need this and that patch after checking out Gnulib," or it has to use the `--avoid=stdint' option and provide the modified `stdint' module in a different directory. The `--local-dir' option to `gnulib-tool' solves this problem. It allows the package to override or augment Gnulib. This means: * You can store files that are to override Gnulib files or modules. * You can store context diffs to be applied to Gnulib files. * You can add modules of your own, that are not (yet) in Gnulib. * You can also add unstructured amounts of code to the library, by grouping the non-Gnulib files of the library in a single kitchen-sink "module." (This kind of kitchen-sink module is not needed when you use the `gnulib-tool' option `--makefile-name'.) In a release tarball, you can distribute the contents of this `--local-dir' directory that will be combinable with newer versions of Gnulib, barring incompatible changes to Gnulib. If the `--local-dir=DIRECTORY' option is specified, then `gnulib-tool' looks in `DIRECTORY' whenever it reads a file from the Gnulib directory. Suppose `gnulib-tool' is looking for FILE. Then: * If `DIRECTORY/FILE' exists, then `gnulib-tool' uses it instead of the file included in Gnulib. * Otherwise, if `DIRECTORY/FILE.diff' exists, then `gnulib-tool' uses the file from Gnulib after applying the diff using the `patch' program. * Otherwise, `gnulib-tool' uses the file included in Gnulib. Please make wise use of this option. It also allows you to easily hold back modifications you make to Gnulib macros in cases it may be better to share them. 6 Miscellaneous Notes ********************* 6.1 Out of memory handling ========================== The gnulib API does not have a standard error code for the out of memory error condition. Instead of adding a non-standard error code, gnulib has chosen to adopt a different strategy. Out of memory handling happens in rare situations, but performing the out of memory error handling after almost all API function invocations pollute your source code and might make it harder to spot more serious problems. The strategy chosen improves code readability and robustness. For most applications, aborting the application with an error message when the out of memory situation occurs is the best that can be wished for. This is how the library behaves by default (using the `xalloc-die' module). However, we realize that some applications may not want to abort execution in any situation. Gnulib supports a hook to let the application regain control and perform its own cleanups when an out of memory situation has occurred. The application can define a function (having a `void' prototype, i.e., no return value and no parameters) and set the library variable `xalloc_die' to that function. The variable should be declared as follows. extern void (*xalloc_die) (void); Gnulib will invoke this function if an out of memory error occurs. Note that the function should not return. Of course, care must be taken to not allocate more memory, as that will likely also fail. 6.2 Obsolete modules ==================== Modules can be marked obsolete. This means that the problems they fix don't occur any more on the platforms that are reasonable porting targets now. `gnulib-tool' warns when obsolete modules are mentioned on the command line, and by default ignores dependencies from modules to obsolete modules. When you pass the option `--with-obsolete' to `gnulib-tool', dependencies to obsolete modules will be included, however, unless blocked through an `--avoid' option. This option is useful if your package should be portable even to very old platforms. In order to mark a module obsolete, you need to add this to the module description: Status: obsolete Notice: This module is obsolete. 6.3 Extra tests modules ======================= Test modules can be marked with some special status attributes. When a test module has such an attribute, `gnulib-tool --import' will not include it by default. The supported status attributes are: `c++-test' Indicates that the test is testing C++ interoperability. Such a test is useful in a C++ or mixed C/C++ package, but is useless in a C package. `longrunning-test' Indicates that the test takes a long time to compile or execute (more than five minutes or so). Such a test is better avoided in a release that is made for the general public. `privileged-test' Indicates that the test will request special privileges, for example, ask for the superuser password. Such a test may hang when run non-interactively and is therefore better avoided in a release that is made for the general public. `unportable-test' Indicates that the test is known to fail on some systems, and that there is no workaround about it. Such a test is better avoided in a release that is made for the general public. `gnulib-tool --import --with-tests' will not include tests marked with these attributes by default. When `gnulib-tool' is invoked with one of the options `--with-c++-tests', `--with-longrunning-tests', `--with-privileged-tests', `--with-unportable-tests', it will include tests despite the corresponding special status attribute. When `gnulib-tool' receives the option `--with-all-tests', it will include all tests regardless of their status attributes. `gnulib-tool --create-testdir --with-tests' and `gnulib-tool --create-megatestdir --with-tests' by default include all tests of modules specified on the command line, regardless of their status attributes. Tests of modules occurring as dependencies are not included by default if they have one of these status attributes. The options `--with-c++-tests', `--with-longrunning-tests', `--with-privileged-tests', `--with-unportable-tests' are recognized here as well. Additionally, `gnulib-tool' also understands the options `--without-c++-tests', `--without-longrunning-tests', `--without-privileged-tests', `--without-unportable-tests'. In order to mark a module with a status attribute, you need to add it to the module description, like this: Status: longrunning-test If only a part of a test deserves a particular status attribute, you can split the module into a primary and a secondary test module, say `foo-tests' and `foo-extra-tests'. Then add a dependency from `foo-tests' to `foo-extra-tests', and mark the `foo-extra-tests' with the particular status attribute. 6.4 A C++ namespace for gnulib ============================== The function definitions provided by Gnulib (`.c' code) are meant to be compiled by a C compiler. The header files (`.h' files), on the other hand, can be used in either C or C++. By default, when used in a C++ compilation unit, the `.h' files declare the same symbols and overrides as in C mode, except that functions defined by Gnulib or by the system are declared as `extern "C"'. It is also possible to indicate to Gnulib to provide many of its symbols in a dedicated C++ namespace. If you define the macro `GNULIB_NAMESPACE' to an identifier, many functions will be defined in the namespace specified by the identifier instead of the global namespace. For example, after you have defined #define GNULIB_NAMESPACE gnulib at the beginning of a compilation unit, Gnulib's `' header file will make available the `open' function as `gnulib::open'. The symbol `open' will still refer to the system's `open' function, with its platform specific bugs and limitations. The symbols provided in the Gnulib namespace are those for which the corresponding header file contains a `_GL_CXXALIAS_RPL' or `_GL_CXXALIAS_SYS' macro invocation. The benefits of this namespace mode are: * Gnulib defines fewer symbols as preprocessor macros. For example, on a platform where `open' has to be overridden, Gnulib normally does `#define open rpl_open'. If your package has a class with a member `open', for example a class `foo' with a method `foo::open', then if you define this member in a compilation unit that includes `' and use it in a compilation unit that does not include `', or vice versa, you will get a link error. Worse: You will not notice this problem on the platform where the system's `open' function works fine. This problem goes away in namespace mode. * It provides a safety check whether the set of modules your package requests from Gnulib is sufficient. For example, if you use the function `gnulib::open' in your code, and you forgot to request the module `open' from Gnulib, you will get a compilation error (regardless of the platform). The drawback of this namespace mode is that the system provided symbols in the global namespace are still present, even when they contain bugs that Gnulib fixes. For example, if you call `open (...)' in your code, it will invoke the possibly buggy system function, even if you have requested the module `open' from gnulib-tool. You can turn on the namespace mode in some compilation units and keep it turned off in others. This can be useful if your package consists of an application layer that does not need to invoke POSIX functions and an operating system interface layer that contains all the OS function calls. In such a situation, you will want to turn on the namespace mode for the application layer--to avoid many preprocessor macro definitions--and turn it off for the OS interface layer--to avoid the drawback of the namespace mode, mentioned above. 6.5 Library version handling ============================ The module `check-version' can be useful when your gnulib application is a system library. You will typically wrap the call to the `check_version' function through a library API, your library header file may contain: #define STRINGPREP_VERSION "0.5.18" ... extern const char *stringprep_check_version (const char *req_version); To avoid ELF symbol collisions with other libraries that use the `check-version' module, add to `config.h' through a AC_DEFINE something like: AC_DEFINE(check_version, stringprep_check_version, [Rename check_version.]) The `stringprep_check_version' function will thus be implemented by the `check_version' module. There are two uses of the interface. The first is a way to provide for applications to find out the version number of the library it uses. The application may contain diagnostic code such as: printf ("Stringprep version: header %s library %s", STRINGPREP_VERSION, stringprep_check_version (NULL)); Separating the library and header file version can be useful when searching for version mismatch related problems. The second uses is as a rudimentary test of proper library version, by making sure the application get a library version that is the same, or newer, than the header file used when building the application. This doesn't catch all problems, libraries may change backwards incompatibly in later versions, but enable applications to require a certain minimum version before it may proceed. Typical uses look like: /* Check version of libgcrypt. */ if (!gcry_check_version (GCRYPT_VERSION)) die ("version mismatch\n"); 6.6 Windows sockets =================== There are several issues when building applications that should work under Windows. The most problematic part is for applications that use sockets. Hopefully, we can add helpful notes to this section that will help you port your application to Windows using gnulib. 6.6.1 Getaddrinfo and WINVER ---------------------------- This was written for the getaddrinfo module, but may be applicable to other functions too. The getaddrinfo function exists in ws2tcpip.h and -lws2_32 on Windows XP. The function declaration is present if `WINVER >= 0x0501'. Windows 2000 does not have getaddrinfo in its `WS2_32.DLL'. Thus, if you want to assume Windows XP or later, you can add AC_DEFINE(WINVER, 0x0501) to avoid compiling the (partial) getaddrinfo implementation. If you want to support Windows 2000, don't do anything. The replacement function will open `WS2_32.DLL' during run-time to see if there is a getaddrinfo function available, and use it when available. 6.7 Libtool and Windows ======================= If you want it to be possible to cross-compile your program to MinGW and you use Libtool, you need to put: AC_LIBTOOL_WIN32_DLL in your `configure.ac'. This sets the correct names for the `OBJDUMP', `DLLTOOL', and `AS' tools for the build. If you are building a library, you will also need to pass `-no-undefined' to make sure Libtool produces a DLL for your library. From a `Makefile.am': libgsasl_la_LDFLAGS += -no-undefined 6.8 License Texinfo sources =========================== Gnulib provides copies of the GNU GPL, GNU LGPL, and GNU FDL licenses in Texinfo form. (The master location is `http://www.gnu.org/licenses/'). These Texinfo documents do not have any node names and structures built into them; for your manual, you should `@include' them in an appropriate `@node'. The conventional name for the GPL node is `Copying' and for the FDL `GNU Free Documentation License'. The LGPL doesn't seem to have a conventional node name. Of course the license texts themselves should not be changed at all. 6.9 Build robot for gnulib ========================== To simplify testing on a wide set of platforms, gnulib is built on many platforms every day and the results are uploaded to: `http://autobuild.josefsson.org/gnulib/' If you wish to help the gnulib development effort with build logs for your favorite platform, you may perform these steps: 1. Create gnulib directory On a machine with recent automake, autoconf, m4 installed and with a gnulib git or cvs checkout (typically a Linux machine), use gnulib-tool --create-megatestdir --with-tests --dir=... Note: The created directory uses ca. 512 MB on disk. 2. Transfer gnulib directory Transfer this directory to a build machine (HP-UX, Cygwin, or whatever). Often it is easier to transfer one file, and this can be achieved by running, inside the directory the following commands: ./configure make dist And then transferring the `dummy-0.tar.gz' file. 3. Build modules On the build machine, run ./do-autobuild (or "nohup ./do-autobuild"). It creates a directory `logs/' with a log file for each module. 4. Submit build logs Submit each log file to Simon's site, either through a mail `echo gnulib__at__autobuild.josefsson.org | sed -e s/__at__/@/` or through netcat autobuild-submit logs/* 7 Building the ISO C and POSIX Substitutes ****************************************** This section shows a radically different way to use Gnulib. You can extract the ISO C / POSIX substitutes part of gnulib by running the command gnulib-tool --create-testdir --source-base=lib \ --dir=/tmp/posixlib `posix-modules` The command `posix-modules' is found in the same directory as `gnulib-tool'. The resulting directory can be built on a particular platform, independently of the program being ported. Then you can configure and build any program, by setting `CPPFLAGS' and `LDFLAGS' at configure time accordingly: set `CPPFLAGS="-I.../posixlib/lib"', plus any essential type definitions and flags that you find in `.../posixlib/config.h', and set `LDFLAGS=".../posixlib/lib/libgnu.a"'. This way of using Gnulib is useful when you don't want to modify the program's source code, or when the program uses a mix between C and C++ sources (requiring separate builds of the `posixlib' for the C compiler and for the C++ compiler). 8 ISO C and POSIX Header File Substitutes ***************************************** This chapter describes which header files specified by ISO C or POSIX are substituted by Gnulib, which portability pitfalls are fixed by Gnulib, and which (known) portability problems are not worked around by Gnulib. The notation "Gnulib module: --" means that Gnulib does not provide a module providing a substitute for the header file. When the list "Portability problems not fixed by Gnulib" is empty, such a module is not needed: No portability problems are known. Otherwise, it indicates that such a module would be useful but is not available: No one so far found this header file important enough to contribute a substitute for it. If you need this particular header file, you may write to `'. 8.1 `aio.h' =========== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/aio.h.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.3, NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, Cygwin, mingw, MSVC 9, Interix 3.5, BeOS. 8.2 `arpa/inet.h' ================= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/arpa_inet.h.html' Gnulib module: arpa_inet Portability problems fixed by Gnulib: * This header file is missing on some platforms: mingw, MSVC 9, BeOS.

Portability problems fixed by Gnulib: * The C11 and C++11 `static_assert', and the C11 `_Static_assert', are not supported by many platforms. For example, GCC versions before 4.6.0 do not support `_Static_assert', and G++ versions through at least 4.6.0 do not support `static_assert'. Portability problems not fixed by Gnulib: * C11 `_Static_assert' and C++11 `static_assert' are keywords that can be used without including `'. The Gnulib substitutes are macros that require including `'. * The C11 `static_assert' and `_Static_assert' can also be used within a `struct' or `union' specifier, in place of an ordinary declaration of a member of the struct or union. The Gnulib substitute can be used only as an ordinary declaration. * In C99, `assert' can be applied to any scalar expression.

Supported compilers include GCC, IBM C, Sun C 5.11 and later, and MSVC 7.0 and later. * Some compilers do not support alignment via `alignas'/`_Alignas' of `auto' variables (i.e., variables on the stack). They diagnose and ignore the alignment: Sun C 5.11. * Some linkers do not support operands of `_Alignas'/`alignas' that are greater than 8: mingw. * Some compilers require the operand of `_Alignas'/`alignas' to be a single integer constant, not an expression: MSVC 7.0 through at least 10.0. * The Sun C 5.11 compiler sometimes mishandles the alignment of multiple external variables that are declared close together with `_Alignas'/`alignas'. This compiler bug causes the Gnulib module `stdalign-tests' to fail. The Sun Studio Developer Bug Report Review Team assigned the internal review ID 2125432 (dated 2011-11-01) to this issue. * `' must be #included before `_Alignas' and `_Alignof' can be used. * You cannot assume that `_Alignas' and `_Alignof' are reserved words; they might be macros. 8.45 `stdarg.h' =============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdarg.h.html' Gnulib module: stdarg Portability problems fixed by Gnulib: * Some compilers (e.g., AIX 5.3 cc) need to be in c99 mode for the builtin `va_copy' to work.

Portability problems not fixed by Gnulib: * `' must be #included before `_Bool' can be used. * You cannot assume that `_Bool' is a typedef; it might be a macro. * Bit-fields of type `bool' are not supported. Portable code should use `unsigned int foo : 1;' rather than `bool foo : 1;'. * Casts and automatic conversions to `bool' don't test against the zero value or the null pointer, as they should. Such casts should only be used if the value is known to be equal to 0 or 1. * You cannot assume that casting a floating point literal to `bool' will result in a constant expression. 8.47 `stddef.h' =============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/stddef.h.html' Gnulib module: stddef Portability problems fixed by Gnulib: * Some old platforms fail to provide `wchar_t'. * Some platforms provide a `NULL' macro that cannot be used in arbitrary expressions: NetBSD 5.0 Portability problems not fixed by Gnulib: * Some platforms provide an `offsetof' macro that cannot be used in arbitrary expressions: Solaris 11 2011-11 This problem can be worked around by parenthesizing the `offsetof' expression in the unlikely case you use it with `sizeof' or `[]'. 8.48 `stdint.h' =============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdint.h.html' Gnulib module: stdint Portability problems fixed by Gnulib: * This header file is missing on some platforms: OpenBSD 3.8, AIX 5.1, HP-UX 11.11, IRIX 6.5, OSF/1 5.1, MSVC 9, Interix 3.5, BeOS. * This header file is very incomplete on some platforms. * The values of `SIG_ATOMIC_MIN' and `SIG_ATOMIC_MAX' are incorrect on some platforms: FreeBSD 6.2 / ia64. * The value of `WINT_MAX' is incorrect on some platforms: mingw. * The values of `INT8_MAX', `UINT8_MAX' etc. are not usable in preprocessor expressions on some platforms: HP-UX 11.23. * The macros `WCHAR_MIN' and `WCHAR_MAX' are not defined in `' (only in `') on some platforms: Dragonfly, BSDI. * On some hosts that predate C++11, when using C++ one must define `__STDC_CONSTANT_MACROS' to make visible the definitions of constant macros such as `INTMAX_C', and one must define `__STDC_LIMIT_MACROS' to make visible the definitions of limit macros such as `INTMAX_MAX'. Portability problems not fixed by Gnulib: * `{uint,int}_fast{8,16,32,64}_t' may not correspond to the fastest types available on the system. Other `' substitutes may define these types differently, so public header files should avoid these types. * Macros are used instead of typedefs. * Some C preprocessors mishandle constants that do not fit in `long int'. For example, as of 2007, Sun C mishandles `#if LLONG_MIN < 0' on a platform with 32-bit `long int' and 64-bit `long long int'. Some older preprocessors mishandle constants ending in `LL'. To work around these problems, compute the value of expressions like `LONG_MAX < LLONG_MAX' at `configure'-time rather than at `#if'-time. The stdint.h module uses `#include_next'. If you wish to install the generated stdint.h file under another name, typically in order to be able to use some of the types defined by stdint.h in your public header file, you could use the following Makefile.am-snippet: BUILT_SOURCES += idn-int.h DISTCLEANFILES += idn-int.h nodist_include_HEADERS += idn-int.h idn-int.h: if test -n "$(STDINT_H)"; then \ sed -e s/include_next/include/ gl/stdint.h > idn-int.h; \ else \ echo '#include ' > idn-int.h; \ fi 8.49 `stdio.h' ============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdio.h.html' Gnulib module: stdio Portability problems fixed by Gnulib: * The type `off_t' is missing on some platforms: glibc 2.8, eglibc 2.11.2 and others. * The type `ssize_t' is missing on some platforms: glibc 2.8, Mac OS X 10.5, Solaris 10, MSVC 9, and others. * The type `va_list' is missing on some platforms: glibc 2.8, OpenBSD 4.0, Solaris 11 2011-11, and others. * Some platforms provide a `NULL' macro that cannot be used in arbitrary expressions: NetBSD 5.0 Portability problems not fixed by Gnulib: 8.50 `stdlib.h' =============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/stdlib.h.html' Gnulib module: stdlib, system-posix Portability problems fixed by the Gnulib module `stdlib': * The macros `EXIT_SUCCESS' and `EXIT_FAILURE' are not defined on some platforms. * The macro `EXIT_FAILURE' is incorrectly defined on Tandem/NSK. * Some platforms provide a `NULL' macro that cannot be used in arbitrary expressions: NetBSD 5.0 Portability problems fixed by the Gnulib module `system-posix': * The macros `WIFSIGNALED', `WIFEXITED', `WIFSTOPPED', `WTERMSIG', `WEXITSTATUS', `WNOHANG', `WUNTRACED', `WSTOPSIG' are not defined in this header file (only in `') on some platforms: MirBSD 10.

Gnulib module: stdnoreturn Portability problems fixed by Gnulib: * This header file is missing on most circa-2012 platforms. Portability problems not fixed by Gnulib: * `' should be #included before `_Noreturn' is used. * You cannot assume that `_Noreturn' is a reserved word; it might be a macro. * On MSVC 9, `noreturn' expands to the empty token sequence, to avoid problems with standard headers that use `__declspec (noreturn)' directly. Although the resulting code operates correctly, the compiler is not informed whether `noreturn' functions do not return, so it may generate incorrect warnings at compile-time, or code that is slightly less optimized. This problem does not occur with * Circa 2012 bleeding-edge GCC with `-Werror=old-style-declaration' requires `_Noreturn' or `noreturn' before the returned type in a declaration, and therefore rejects valid but unusually-worded declarations such as `void _Noreturn foo (void);'. 8.52 `string.h' =============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/string.h.html' Gnulib module: string Portability problems fixed by Gnulib: * Some platforms provide a `NULL' macro that cannot be used in arbitrary expressions: NetBSD 5.0 Portability problems not fixed by Gnulib: 8.53 `strings.h' ================ POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/strings.h.html' Gnulib module: strings Portability problems fixed by Gnulib: * This header file is not self-contained on some platforms: Minix 3.1.8.

Use the gnulib module `stat-time' for accessors to portably get at subsecond resolution. Portability problems not fixed by Gnulib: * The macro `S_IFBLK' is missing on some platforms: MSVC 9. * On Windows platforms (excluding Cygwin), `st_ino' is always 0. * On OpenVMS, `st_ino' is an array of three `ino_t' values, not a single value. * To partially work around the previous two problems, you can test for nonzero `st_ino' and use the Gnulib `same-inode' module to compare nonzero values. For example, `(a.st_ino && SAME_INODE (a, b))' is true if the `struct stat' values `a' and `b' are known to represent the same file, `(a.st_ino && !SAME_INODE (a, b))' is true if they are known to represent different files, and `!a.st_ino' is true if it is not known whether they represent different files. * On some platforms, two different files may have the same `st_dev' and `st_ino' values, even when `st_ino' is nonzero: * GNU/Linux NFS servers that export all local file systems as a single NFS file system, if a local `st_dev' exceeds 255, or if a local `st_ino' exceeds 16777215. * Network Appliance NFS servers in snapshot directories; see Network Appliance bug #195. * ClearCase MVFS; see bug id ATRia04618. One partial workaround is to compare other file metadata such as `st_mode' and `st_mtime' to detect this bug, but this approach does not work on files whose metadata are being changed by other programs. * On some file systems, `st_size' contains bogus information for symlinks; use the Gnulib module `areadlink-with-size' for a better way to get symlink contents. 8.64 `sys/statvfs.h' ==================== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/sys_statvfs.h.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This header file is missing on some platforms: Mac OS X 10.3, OpenBSD 3.8, mingw, MSVC 9. 8.65 `sys/time.h' ================= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/basedefs/sys_time.h.html' Gnulib module: sys_time Portability problems fixed by Gnulib: * This header file is missing on some platforms: MSVC 9. * `struct timeval' is not defined on some platforms. * `struct timeval' is defined with a `tv_sec' type that is narrower than `time_t' on some native Windows platforms: mingw64 in 64-bit mode, mingw64 in 32-bit mode when `__MINGW_USE_VC2005_COMPAT' is defined, MSVC 9 in 64-bit mode, MSVC 9 in 32-bit mode when `_USE_32BIT_TIME_T' is not defined.

The notation "Gnulib module: --" means that Gnulib does not provide a module providing a substitute for the function. When the list "Portability problems not fixed by Gnulib" is empty, such a module is not needed: No portability problems are known. Otherwise, it indicates that such a module would be useful but is not available: No one so far found this function important enough to contribute a substitute for it.

Gnulib: Portability problems not fixed by Gnulib: * This function may overflow its internal buffer if an invalid year is passed. * The `ctime' function need not be reentrant, and consequently is not required to be thread safe. Implementations of `ctime' typically write the time stamp into static buffer. If two threads call `ctime' at roughly the same time, you might end up with the wrong date in one of the threads, or some undefined string. There is a re-entrant interface `ctime_r'. A more flexible function is `strftime'. However, note that it is locale dependent. 9.169 `ctime_r' =============== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/ctime_r.html' Gnulib module: extensions Portability problems fixed by Gnulib: * This function has an incompatible declaration on some platforms: Solaris 11 2011-11 (when `_POSIX_PTHREAD_SEMANTICS' is not defined). Portability problems not fixed by Gnulib: * This function is missing on some platforms: mingw, MSVC 9. * This function may put more than 26 bytes into the argument buffer if an invalid year is passed. `ctime_r' takes a pre-allocated buffer and length of the buffer, and returns `NULL' on errors. The input buffer should be at least 26 bytes in size. The output string is locale-independent. However, years can have more than 4 digits if `time_t' is sufficiently wide, so the length of the required output buffer is not easy to determine. Increasing the buffer size when `ctime_r' returns `NULL' is not necessarily sufficient. The `NULL' return value could mean some other error condition, which will not go away by increasing the buffer size. A more flexible function is `strftime'. However, note that it is locale dependent. 9.170 `daylight' ================ POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/daylight.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This variable is missing on some platforms: Mac OS X 10.3, FreeBSD 6.0, OpenBSD 3.8, IRIX 6.5, OSF/1 5.1. * The address of this variable is not a compile-time constant on some platforms: Cygwin, mingw. 9.171 `dbm_clearerr' ==================== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_clearerr.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, HP-UX 11.11, IRIX 5.3, OSF/1 5.1, Solaris 2.5.1, Cygwin, mingw, MSVC 9, BeOS. 9.172 `dbm_close' ================= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_close.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.173 `dbm_delete' ================== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_delete.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.174 `dbm_error' ================= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_error.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, HP-UX 11.11, IRIX 5.3, OSF/1 4.0, Solaris 2.5.1, Cygwin, mingw, MSVC 9, BeOS. 9.175 `dbm_fetch' ================= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_fetch.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.176 `dbm_firstkey' ==================== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_firstkey.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.177 `dbm_nextkey' =================== POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_nextkey.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.178 `dbm_open' ================ POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_open.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.179 `dbm_store' ================= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dbm_store.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: * This function is missing on some platforms: glibc 2.3.6, Cygwin, mingw, MSVC 9, BeOS. 9.180 `difftime' ================ POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/difftime.html' Gnulib module: -- Portability problems fixed by Gnulib: Portability problems not fixed by Gnulib: 9.181 `dirfd' ============= POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/dirfd.html' Gnulib module: dirfd Portability problems fixed by Gnulib: * This function is missing on some platforms: Minix 3.1.8, AIX 7.1, HP-UX 11, OSF/1 5.1, Solaris 10, mingw, MSVC 9.

Portability problems not fixed by Gnulib: * It is not portable to call `realloc' with a size of 0. With a NULL pointer argument, this is the same ambiguity as `malloc (0)' on whether a unique zero-size object is created. With a non-NULL pointer argument, C99 requires that if `realloc (p, 0)' returns `NULL' then `p' is still valid. Among implementations that obey C99, behavior varies on whether `realloc (p, 0)' always fails and leaves `p' valid, or usually succeeds and returns a unique zero-size object; either way, a program not suspecting these semantics will leak memory (either the still-valid `p', or the non-NULL return value). Meanwhile, several implementations violate C99, by always calling `free (p)' but returning NULL: glibc, Cygwin Extension: Gnulib provides a module `realloc-gnu' that substitutes a `realloc' implementation that behaves more like the glibc implementation. 9.848 `realpath' ================ POSIX specification: `http://www.opengroup.org/onlinepubs/9699919799/functions/realpath.html' Gnulib module: canonicalize-lgpl Portability problems fixed by Gnulib: * This function is missing on some platforms: mingw, MSVC 9, BeOS. * This function does not allow for a NULL `resolved' parameter on some platforms: Mac OS X 10.5, FreeBSD 6.4, OpenBSD 4.4, Solaris 10. * This function does not always return an absolute path on some platforms: Solaris 10. * This function fails to detect trailing slashes on non-directories on some platforms: glibc 2.3.5. * This function fails to recognize non-directories followed `..' on some platforms: cygwin. * This function misbehaves on consecutive slashes on some platforms: AIX 7.

The notation "Gnulib module: --" means that Gnulib does not provide a module providing a substitute for the function. When the list "Portability problems not fixed by Gnulib" is empty, such a module is not needed: No portability problems are known. Otherwise, it indicates that such a module would be useful but is not available: No one so far found this function important enough to contribute a substitute for it. If you need this particular function, you may write to `'. This list of functions is sorted according to the header that declares them. 12.1 Glibc Extensions to `' ================================== 12.1.1 `aio_init' ----------------- Gnulib module: --
