And of course, since we store sources in git, you already have such a hash value at your disposal: $CC -DBUILD_HASH=$(git rev-parse HEAD) ... coupled with glue(qemu_module_init_, BUILD_HASH) where the only trick is to figure out how to bake in a hash when building from a released tarball rather than git. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
