|
| +# This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/.
|
| +# It may be run two ways:
|
| +# - from a git repository in which the "git describe" command below
|
| +# produces useful output (thus requiring at least one signed tag)
|
| +# - from a non-git-repo directory containing a .tarball-version file, which
|
| +# presumes this script is invoked like "./git-version-gen .tarball-version".
|
| +
|
| +# In order to use intra-version strings in your project, you will need two
|
| +# separate generated version string files:
|
| +#
|
| +# .tarball-version - present only in a distribution tarball, and not in
|
| +# a checked-out repository. Created with contents that were learned at
|
| +# the last time autoconf was run, and used by git-version-gen. Must not
|
| +# be present in either $(srcdir) or $(builddir) for git-version-gen to
|
| +# give accurate answers during normal development with a checked out tree,
|
| +# but must be present in a tarball when there is no version control system.
|
| +# Therefore, it cannot be used in any dependencies. GNUmakefile has
|
| +# hooks to force a reconfigure at distribution time to get the value
|
| +# correct, without penalizing normal development with extra reconfigures.
|
| +#
|
| +# .version - present in a checked-out repository and in a distribution
|
| +# tarball. Usable in dependencies, particularly for files that don't
|
| +# want to depend on config.h but do want to track version changes.
|
| +# Delete this file prior to any autoconf run where you want to rebuild
|
| +# files to pick up a version string change; and leave it stale to
|
| +# minimize rebuild time after unrelated changes to configure sources.
|
| +#
|
| +# It is probably wise to add these two files to .gitignore, so that you
|
| +# don't accidentally commit either generated file.
|
| +#
|
| +# Use the following line in your configure.ac, so that $(VERSION) will
|
| +# automatically be up-to-date each time configure is run (and note that
|
| +# since configure.ac no longer includes a version string, Makefile rules
|
| +# should not depend on configure.ac for version updates).
|
| +#

| +# AC_INIT([GNU project],
|
| +# m4_esyscmd([build-aux/git-version-gen .tarball-version]),
|
| +# [bug-project@example])
|
| +#
|
| +# Then use the following lines in your Makefile.am, so that .version
|
| +# will be present for dependencies, and so that .tarball-version will
|
| +# exist in distribution tarballs.
