Ooops, I read too fast. I thought that you were recommending me to define MY_DATA_PATH in the configure call: configure CPPFLAGS='-DMY_DATA_PATH="\"$(pkgdatadir)\""' Luckily it also works, since MY_DATA_PATH is defined twice but the compiler chooses the last definition, which belongs to the CPPFLAGS value. It's a great thing for the Autotools that the user configuration prevails over the developer's :) Regards, Alberto _______________________________________________ Autoconf mailing list Autoconf@gnu.org http://lists.gnu.org/mailman/listinfo/autoconf
