Hi again, I found AC_LANG_WERROR which seems to do what I want. I also found this discussion on how to revert AC_LANG_WERROR http://lists.gnu.org/archive/html/autoconf/2007-04/msg00030.html but guess that discussion died. Cheers, Peter On 7/21/12 7:26 PM, Peter Johansson wrote:
Hi autoconfers,In one of my projects, we noticed that some versions of g++ does not recognize option '-pthread', but gives a warningi686-apple-darwin8-g++-4.0.1: unrecognized option '-pthread'Now I'd like to test this at configure time, so I wonder if there is a good mechanism to test if compiler is complaining to stderr.Or do I need to write a low-level macro myself for this? Thank you. Peter _______________________________________________ Autoconf mailing list address@hidden https://lists.gnu.org/mailman/listinfo/autoconf
