media-libs/libopenshot-0.1.0 would not compile; error was always this: In file included from /var/tmp/portage/media-libs/libopenshot-0.1.0/work/src/.. /include/FFmpegReader.h:47:0, from /var/tmp/portage/media-libs/libopenshot-0.1.0/work/src/../include/ChunkReader.h:32, from /var/tmp/portage/media-libs/libopenshot-0.1.0/work/src/ChunkReader.cpp:28: /var/tmp/portage/media-libs/libopenshot-0.1.0/work/src/../include/OpenMPUtilities.h:31:17: fatal error: omp.h: No such file or directory compilation terminated. src/CMakeFiles/openshot.dir/build.make:186: recipe for target 'src/CMakeFiles/openshot.dir/ChunkReader.cpp.o' failed my gcc-5.3.0 on ~amd64 was compiled with USE="-openmp" i recompiled gcc with USE="openmp" and media-libs/libopenshot-0.1.0 compiled. maybe the ebuild should check/warn about this. also posted here: https://forums.gentoo.org/viewtopic.php?p=7909732 i idi not write a patch because the solution worked for me.
