>>> Source configured.

CPU_FLAGS_X86 var does not affect src_configure, because CPU_FEATURES= var is not used in src_configure function of all libpostproc ebuilds. Also list in CPU_FEATURES= is incomplete: it does not include '3dnowext sse ssse3 avx'.
Comment 1 Nikoli 2015-03-01 05:26:12 UTC
After looking at bug #455814 it seems that CPU_FEATURES= list is complete, instead build system needs cleanup.

Comment 8 Kenton Groombridge 2017-02-10 02:33:45 UTC
This has become an issue on my system a few days ago with the version bump of libav-12 which causes a rebuild of this package.

There will probably be a few other folks having this issue as this package hasn't been built on my system for some time now.

libpostproc-10.20140517-no-deprecated-cpu-flag.patch

libav no longer defines AV_CPU_FLAG_MMX2. See http://lists.libav.org/pipermail/libav-commits/2015-August/017354.html.  AFAIK, AV_CPU_FLAG_MMXEXT should provide equivalent behavior.
