The major problem with distclean is that it completely falls over in the scenario where the source code has changed; the new distclean won't know about *old* object files it no longer builds, files renamed, etc. In GNOME we just this cycle landed this patch to use "git clean -dfx" instead of "make distclean" if possible: https://bugzilla.gnome.org/show_bug.cgi?id=656081 It might be interesting to have an option to run: "git init; git add .; git commit -a -m auto-import" on each tarball build in OE. I've been considering doing this for jhbuild. (My latest build system *only* builds from git repositories, so it works there =) ) _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
