When attempting to emerge media-libs/opencv, the compilation halts with 'fatal error: /usr/include/libpng/png.h: No such file or directory' media-libs/libpng installs /usr/include/libpng16/ but does not create a /usr/include/libpng symlink to it Reproducible: Always Steps to Reproduce: 1.emerge -av opencv 2. 3. Actual Results: Compile fails Expected Results: Compile succeeds if a symlink is created via 'ln -s libpng16 libpng' within /usr/include the compilation of opencv gets further. It still fails for me, but gets further at least.
Please show evidence that this is necessary as it works for me without a symlink
Perhaps we can see something in the logs. Please recompile and *attach* the logfiles and paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket The logs must be part of the ticket, but not on external websites. Please reopen this ticket (Status:unconfirmed) afterwards.

It seems the real issue here is a failed fma3 test: CMake Error at cmake/OpenCVCompilerOptimizations.cmake:449 (message): Required baseline optimization is not supported: FMA3 (CPU_BASELINE_REQUIRE=;SSE;SSE2;SSE3;SSSE3;SSE4_1;SSE4_2;POPCNT;AVX;FMA3) Does opencv compile fine with USE="-cpu_flags_x86_fma3" ?
Yeah, this looks like a dupe of bug #656638. Missing /usr/include/libpng is not an issue here.
Thank you! That did it.
