Write a rule in Makefile to generate a value from "git describe" combined with a possible git tree cleanness suffix, and write into a new header. $ cat qemu-version.h #define QEMU_PKGVERSION "-v2.6.0-557-gd6550e9-dirty" Include the header in .c files where the macro is referenced. It's not necessary to include it in all files, otherwise each time the content of the file changes, all sources have to be recompiled.
