Subject: configure.in: Generate version dynamically using version-gen.sh.
X-Git-Tag: collectd-4.1.0~28^2^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1b739da931a8edb0e3a1c283fd464c4fd9805b67;p=collectd.git

configure.in: Generate version dynamically using version-gen.sh.

This dynamically creates the version string when the configure script is
created. If run from within a repository the output of "git describe" is
used to create the version string. Else it defaults to a hardcoded value
which should be something like "$latest_version.git".

The idea is to update the default version to the new version (without
".git" appended) as the last commit of a release cycle. This commit is
tagged as the new version. The next commit after the release will set the
default version to "$new_version.git".

The benefit is that a pre-release with a quite well defined and unique
version can be easily created at any time.
