Hello in configure.ac, we do (I simplify) PACKAGE_DATA_DIR=${datadir} ACSUBST([PACKAGE_DATA_DIR]) etc... AC_CONFIG_FILES([ file ]) And in file.in: path=@PACKAGE_DATA_DIR@ It's not good as $datadir is not defined at configure time. One solution is to use a sed command in a make rule in Makefile.am. Is there a better solution to do what we want ? thank you Vincent Torri _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
