AntTweakBar-1.14-1 is not built with $RPM_OPT_FLAGS: http://kojipkgs.fedoraproject.org/packages/AntTweakBar/1.14/1.fc16/data/logs/x86_64/build.log 1.13-6 did not have this problem: http://kojipkgs.fedoraproject.org/packages/AntTweakBar/1.13/6.fc15/data/logs/x86_64/build.log grepping through the 1.14 source tarball I find nothing related to FEDORA_CXXFLAGS. Setting CXXCFG instead of it might fix it (untested).
Huh. I didn't change the build setup at all, so it's strange that it would have worked right in the old version. I pushed a 1.14-2 that fixes this issue.
(In reply to comment #1) > Huh. I didn't change the build setup at all, The AntTweakBar-makefile.patch which was in 1.13-6 had stuff related to FEDORA_CXXFLAGS.
Ah. Well now I just feel silly, since I wrote that patch. :) Setting the proper variable for the build system in the spec file makes more sense anyway though, at least.
