I am observing a link error on pcsx2-9999 against wxGTK:3.0 . Rebuilding wxGTK with gcc makes the problem go away. I'll post the error message later. I am not sure if this is worth a gentoo bug report, but perhaps ebuild could use a compiler check, if the problem is reproducible across other packages. afaik pcsx2 links against 32bit libraries of wxGTK, so this could be limited only to 32bit library. My gentoo install is up to date ~amd64 .

Which GCC version? Are there other dependencies of wxGTK built with GCC on your system? These ones are usually caused by C++-11 ABI incompatibility. /usr/lib32/libwx_baseu-3.0.so: undefined reference to `std::__cxx11::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> >::_M_create(unsigned int&, unsigned int)@GLIBCXX_3.4.21' Please post emerge --info.
I believe it was most up to date gcc on ~amd64 at the time of report. I'll try repeating the problem and posting the emerge info it it is still valid.
I think this issue is outdated at this point. I'll close this one, since i could not reproduce the issue.
