These are installation instructions for Bash.
The simplest way to compile Bash is:
cdto the directory containing the source code and type ‘./configure’ to configure Bash for your system. If you’re using
cshon an old version of System V, you might need to type ‘sh ./configure’ instead to prevent
cshfrom trying to execute
configure takes some time.
While running, it prints messages telling which features it is

bashbug. This will also install the manual pages and Info file.
configure shell script attempts to guess correct
values for various system-dependent variables used during
compilation. It uses those values to create a Makefile in
each directory of the package (the top directory, the
builtins, doc, and support directories,
each directory under lib, and several others). It also creates a
config.h file containing system-dependent definitions.
Finally, it creates a shell script named
config.status that you
can run in the future to recreate the current configuration, a
file config.cache that saves the results of its tests to
speed up reconfiguring, and a file config.log containing
compiler output (useful mainly for debugging
If at some point
config.cache contains results you don’t want to keep, you
may remove or edit it.
To find out more about the options and arguments that the
configure script understands, type
bash-4.2$ ./configure --help
at the Bash prompt in your Bash source directory.
If you want to build Bash in a directory separate from the source directory – to build for multiple architectures, for example – just use the full path to the configure script. The following commands will build bash in a directory under /usr/local/build from the source code in /usr/local/src/bash-4.4:
mkdir /usr/local/build/bash-4.4 cd /usr/local/build/bash-4.4 bash /usr/local/src/bash-4.4/configure make
See Compiling For Multiple Architectures for more information about building in a directory separate from the source.
If you need to do unusual things to compile Bash, please
try to figure out how
configure could check whether or not
to do them, and mail diffs or instructions to
firstname.lastname@example.org so they can be
considered for the next release.
The file configure.ac is used to create
by a program called Autoconf. You only need
configure.ac if you want to change it or regenerate
configure using a newer version of Autoconf. If
you do this, make sure you are using Autoconf version 2.50 or
You can remove the program binaries and object files from the
source code directory by typing ‘make clean’. To also remove the
configure created (so you can compile Bash for
a different kind of computer), type ‘make distclean’.
