| # 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. | ||
| # | ||
| # BUILT_SOURCES = $(top_srcdir)/.version | ||
| # $(top_srcdir)/.version: | ||
| # echo $(VERSION) > $@-t && mv $@-t $@ | ||
| # dist-hook: | ||
