I am trying to make the inclusion of a module of my program an option configurable in ./configure but can't get it right. At the moment I have in configure.ac .... AC_ARG_ENABLE(webcam, [ --disable-webcam disable use of webcam]) AC_ARG_ENABLE(voice, [ --disable-voice disable use of voice]) .... AC_DEFINE([USE_WEBCAM], [], [enable/disable webcam broadcaster]) AC_DEFINE([USE_VOICE], [], [enable/disable voice chat]) .... in config.h.in .... /* enable/disable voice chat */ #undef USE_VOICE /* enable/disable webcam broadcasterDescription */ #undef USE_WEBCAM .... and #ifdef USE_VOICE ... #endif or #ifdef USE_WEBCAM ... #endif surrounding the relevent code in the source but this doesn't seem to be working. Can someone please pointme towards clear explaination of how to do this AND/OR a solution or example /]/]ik _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
