Created attachment 419556 [details] emerge --info mpv After gcc-5.3.0 upgrade, I tried to do the recommended rebuilds. mpv-0.11.0, which I had already installed using gcc-4.9.3, failed to build in the normal revdep-rebuild, so (as with several others) I listed it to try again later. However, it's one of only a handful that still refuses to build, after everything else is rebuilt and all other current ~amd64 upgrades (deep) are applied.

I'll try turning that off after I finish filing this. I already tried manually rebuilding libvdpau and libva-vdpau-driver, and I already tried with CCACHE_RECACHE=1, which turns it write-only (update the cache only, don't use it), just in case. Meanwhile, I'll attach emerge --info mpv here, and the full build log afterward.
Created attachment 419558 [details] full build log Here's the full build log (for USE flags as above, tho the below discusses other workarounds I've tried). FWIW, I tried building with USE=-vdpau, and despite my double-check that it passed --disable-vdpau at the configure step, it still failed with the same vdpau related errors. Maybe I need to rebuild ffmpeg? No, that doesn't work, at least not with USE=vdpau for both. With USE=-vdpau for both ffmpeg and mpv (and the ffmpeg virtual), maybe? No, same thing there. Time to step back and try something else, like moderating cflags/cxxflags...
OK, it was cflags/cxxflags, specifically -fmerge-all-constants. Without that, it works fine. gcc-5.3 must treat that significantly differently than it did before, as AFAIK, that's the first time -fmerge-all-constants has given me problems /ever/, on /any/ package, and it definitely worked fine with gcc 4.9.3 as this was a reinstall, with the original built with it. I could close this now, but I'll leave it open for the moment, in case others have the problem and/or in case you maintainers want to prune it from cflags in the ebuild. If I remember, I'll close it in a few weeks/months if it's still open. Meanwhile, off to see if that's the problem with a couple other pkgs that wouldn't rebuild, or if the gcc release notes for 5.3 or earlier 5.x say anything about it... =:^) Anyway, thanks for the work maintaining! =:^)
