The lib needs to filter the CXXFLAG -fvisibility-inlines-hidden. If this CXXFLAG is used, some apps that build against wxGTK fail to compile, complaining about problems with wxColor. Problematic apps I discovered so far are: games-strategy/scorched3d-41.3-r1 ; games-util/springlobby (not in official portage tree) Reproducible: Always Steps to Reproduce: 1. Enable offending CXXFLAGS="-fvisibility-inlines-hidden" in make.conf 2. Emerge x11-libs/wxGTK-2.8.7.1-r1 3. eselect wxwidgets set gtk2-unicode-release-2.8 4. Try to emerge games-strategy/scorched3d-41.3-r1 Actual Results: Compilation aborts with error regarding wxColor. I'm going to post the exact error tomorrow, as I do not have time to reproduce again right now. Or you could try it yourself. Expected Results: Successful compilation The CXXFLAG should be filtered to circumvent this problem.
Instead filing such a bug here, you should ask upstream to actually fix this. We do not support arbitrary gcc flags and the maintainer is fine to say no, he won't filter, as it means essentially to hide bugs, not fixing them.
don't use fvisibility-inlines-hidden. it breaks ABI.
Well, I'm not using it. I would be insane to. Why _not_ filter it? It's one line in the ebuild, and it won't hurt. Nothing breaks. People who are dumb enough to use that CXXFLAG will have one less thing to be afraid of, that's all
