i had some trouble figuring out how to get the include macro inside another (parameterized) macro. this works in m4: changequote(`[', `]') define([nodot], [[\([_0-9a-zA-Z]+\)]]) define([reversion], [^nodot\.nodot\.nodot$]) define([getver], [regexp($1, reversion, $2)]) define([readver], [getver(include($1), [\&])]) readver([VERSION]) this fails in configure.ac (autoconf 2.69): m4_define([nodot], [[\([_0-9a-zA-Z]+\)]]) m4_define([reversion], [^nodot\.nodot\.nodot$]) m4_define([getver], [regexp($1, reversion, $2)]) m4_define([readver], [getver(m4_include($1), [\&])]) m4_define([ver], readver([VERSION])) messages: aclocal: error: configure.ac:7: file '$1' does not exist autoreconf: aclocal failed with exit status: 1 i can get it to work by quoting the m4_include macro name: m4_define([readver], [getver([m4_include]($1), [\&])]) why is this? can you point me to the relevant passages in the manual? i admit i haven't read it all (yet). -- roman _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
