I'm assuming you mean using something like > "git describe --tags"? Use of this could be contingent on either a > .git dir, or lack of a version file added to release tarballs. Linux and u-boot use a script like . Assuming the makefile has the release version numbering in it and tags to match git, results in 'dirty', 'sha' and 'commits-since-last-tag' style addons to the version number. Like: U-Boot SPL 2011.09-00036-ga61c346-dirty Dirty (uncommitted changes), 36 commits since last tag, sha of a61c346 is HEAD. Would this kind of notation work? :https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/scripts/setlocalversion > The > only thing that's not clear is how to handle non-release source trees > present on a build system that lacks a working git installation. How often is this a concern? How are people obtaining non-release source trees not via an scm tool? -Andrew
