We are trying to find a solution for http://lists.gnu.org/archive/html/autoconf/2016-07/msg00003.html. We are contemplating detecting an Autoconf run in the preprocessor, and then (if its Autoconf) disabling the test that triggers the '#error`. Is there a preprocessor macro defined by Autotools to detect when software is being configured by the tool? My apologies for asking; I cannot simply run `g++ -dM -E - </dev/null` because it will lack Autoconf specific defines. Thanks in advance. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
