Warning: This is the manual of the legacy Guile 2.2 series. You may want to read the manual of the current stable series instead.

6.23.1 Configuration, Build and Installation

The following procedures and variables provide information about how Guile was configured, built and installed on your system.

Scheme Procedure: version

Scheme Procedure: effective-version

Scheme Procedure: major-version

Scheme Procedure: minor-version

Scheme Procedure: micro-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/2.2/

(version) ⇒ "2.2.0"
(effective-version) ⇒ "2.2"
(major-version) ⇒ "2"
(minor-version) ⇒ "2"
(micro-version) ⇒ "0"

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/2.2.

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.

Scheme Procedure: %site-ccache-dir

C Function: scm_sys_site_ccache_dir ()

Return the directory where users should install compiled .go files for use with this version of Guile. Might look something like /usr/lib/guile/2.2/site-ccache.

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-2.2 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 in GNU Libtool). 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 in The GNU Autoconf Manual).
