Well, we don't support your CFLAGS/CXXFLAGS/LDFLAGS... that would make this invalid... anyway, I also see you are using gold linker... maybe that is the issue and you could try with bfd linker. If that works, please report this underlinking issue to upstream -> bugzilla.gnome.org Then, paste here the link to let us track the issue
I stripped my C/CXX/LDFLAGS and still ran into the same issue. Switching to ld.bfd immediately did the trick and the build ran through without any problems. Following Pacho's advice I reported the issue upstream: https://bugzilla.gnome.org/show_bug.cgi?id=769603
Created attachment 442794 [details, diff] gtk+-3.20.8-fix-underlinking-with-ld-gold.patch This patch (from upstream bug) fixes the issue with underlinking with ld.gold
Created attachment 442796 [details, diff] gtk+-3.20.8.ebuild.patch Patch for gtk+-3.20.8.ebuild
Created attachment 443046 [details, diff] fix underlinkage with gold The attached patch was accepted by upstream, and should be included in the next version. I am also including a patch for the ebuild if you want to have the fix applied to 3.20.8.
Created attachment 443048 [details, diff] gtk+-3.20.8.ebuild.patch
This should be fixed with 3.20.9.
I can confirm this was fixed as of 3.20.9. The standard ebuild is working fine.
Thanks for reporting.
