Freeciv ( http://www.freeciv.org ) configure.ac has AC_INIT like this: AC_INIT([freeciv], [m4_esyscmd([./fc_version | tr -d '\n'])]) This results in warnings from aclocal, autoheader, autoconf and automake: configure.ac:5: warning: AC_INIT: not a literal: m4_esyscmd([./fc_version | tr -d '\n']) Resulting configure seems to work correctly, and it even has correct line # Generated by GNU Autoconf 2.68 for freeciv 2.3.99-dev in it. What is wrong with our AC_INIT? I've seen use of m4_esyscmd recommended for similar cases in this list, so I assume it can be somehow used without such warning. - ML _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
