— Scheme Procedure: version

— C Function: scm_version ()
— C Function: scm_effective_version ()
— C Function: scm_major_version ()
— C Function: scm_minor_version ()
— C Function: scm_micro_version ()

Return a string describing Guile's full version number, effective version number, major, minor or micro version number, respectively. The effective-version function returns the version name that should remain unchanged during a stable series. Currently that means that it omits the micro version. The effective version should be used for items like the versioned share directory name i.e. /usr/share/guile/2.0/

          (version) ⇒ "2.0.4"
          (effective-version) ⇒ "2.0"
          (major-version) ⇒ "2"
          (minor-version) ⇒ "0"
          (micro-version) ⇒ "4"

— Scheme Procedure: %package-data-dir
— C Function: scm_sys_package_data_dir ()

Return the name of the directory under which Guile Scheme files in general are stored. On Unix-like systems, this is usually /usr/local/share/guile or /usr/share/guile.

— Scheme Procedure: %library-dir
— C Function: scm_sys_library_dir ()

Return the name of the directory where the Guile Scheme files that belong to the core Guile installation (as opposed to files from a 3rd party package) are installed. On Unix-like systems this is usually /usr/local/share/guile/GUILE_EFFECTIVE_VERSION or /usr/share/guile/GUILE_EFFECTIVE_VERSION;

for example /usr/local/share/guile/2.0.

— Scheme Procedure: %site-dir
— C Function: scm_sys_site_dir ()

Return the name of the directory where Guile Scheme files specific to your site should be installed. On Unix-like systems, this is usually /usr/local/share/guile/site or /usr/share/guile/site.

— Variable: %guile-build-info

Alist of information collected during the building of a particular Guile. Entries can be grouped into one of several categories: directories, env vars, and versioning info.

Briefly, here are the keys in %guile-build-info, by group:

directories

srcdir, top_srcdir, prefix, exec_prefix, bindir, sbindir, libexecdir, datadir, sysconfdir, sharedstatedir, localstatedir, libdir, infodir, mandir, includedir, pkgdatadir, pkglibdir, pkgincludedir

env vars

LIBS

versioning info

guileversion, libguileinterface, buildstamp

Values are all strings. The value for LIBS is typically found also as a part of pkg-config --libs guile-2.0 output. The value for guileversion has form X.Y.Z, and should be the same as returned by (version). The value for libguileinterface is libtool compatible and has form CURRENT:REVISION:AGE (see Library interface versions). The value for buildstamp is the output of the command ‘date -u +'%Y-%m-%d %T'’ (UTC).

In the source, %guile-build-info is initialized from libguile/libpath.h, which is completely generated, so deleting this file before a build guarantees up-to-date values for that build.

— Variable: %host-type

The canonical host type (GNU triplet) of the host Guile was configured for, e.g., "x86_64-unknown-linux-gnu" (see Canonicalizing).
