# 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).
