Hello all, can you please attach these following logs? [1][2] Thank you [1] /var/tmp/portage/media-libs/opencv-3.4.1/work/opencv-3.4.1-abi_x86_32.x86/CMakeFiles/CMakeOutput.log [2] /var/tmp/portage/media-libs/opencv-3.4.1/work/opencv-3.4.1-abi_x86_32.x86/CMakeFiles/CMakeError.log
Same problem here with AMD FX-8350 CPU. Checking the cpu flags showed: CPU_FLAGS_X86="avx popcnt sse sse2 sse4_1 sse4_2 ssse3" Looks good. Comparing the ebuild form 3.3 and 3.4 showed a lot of changes, especially for the CPU flags. Some of the cpu flags in IUSE are not supported by my CPU. Next step, I removed the unsupported flags from IUSE in ebuild: cpu_flags_x86_sse3 cpu_flags_x86_avx2 cpu_flags_x86_fma3 and removed also: -DENABLE_SSE3=$(usex cpu_flags_x86_sse3) -DENABLE_AVX2=$(usex cpu_flags_x86_avx2) -DENABLE_FMA3=$(usex cpu_flags_x86_fma3) Copied the "adjusted" ebuild to my overlay directory and installed opencv successfully with this ebuild. I don't know how to verify if opencv is working correctly and I'm not sure, if removing the flags causes some problems.

Could you submit those logs I asked in previous comments?
I think I figured out the problem. Adding "popcnt" to CPU_FLAGS_X86 fixed it. Looks like the problem is caused by having the sse4_2 feature without popcnt. According to OpenCV, sse4_2 implies popcnt: ocv_update(CPU_SSE4_2_IMPLIES "SSE4_1;POPCNT") And indeed my CPU supports popcnt. So it looks like OpenCV just really doesn't like it when you give it a CPU flags combination that is "impossible" in the sense that some features are not listed that should be implied by others. I guess it goes "you don't have popcnt, you must not have sse4_2" and then bails when you actually asked it to use sse4_2. Maybe this should be fixed at a higher level? Looks like this would be a useful feature higher up in an eclass or similar, e.g. automatically imply dependencies, or complain when you're missing flags.
@Michael Baer try adding all the older features your CPU supports but which aren't listed in your current CPU_FLAGS_X86, e.g. CPU_FLAGS_X86="mmx mmxext sse sse2 sse3 ssse3 sse4_1 popcnt sse4_2 avx"
I think this warrants REQUIRED_USE constraints encoding the same dependencies that OpenCV expects, to force users to enable any missing flags. Something like this: REQUIRED_USE=" cpu_flags_x86_avx2 ? ( cpu_flags_x86_avx cpu_flags_x86_fma3 ) cpu_flags_x86_fma3 ? ( cpu_flags_x86_avx2 ) cpu_flags_x86_avx ? ( cpu_flags_x86_sse4_2 ) cpu_flags_x86_sse4_2 ? ( cpu_flags_x86_sse4_1 cpu_flags_x86_popcnt ) cpu_flags_x86_popcnt ? ( cpu_flags_x86_sse4_1 ) cpu_flags_x86_sse4_1 ? ( cpu_flags_x86_sse3 cpu_flags_x86_ssse3 ) cpu_flags_x86_ssse3 ? ( cpu_flags_x86_sse3 ) cpu_flags_x86_sse3 ? ( cpu_flags_x86_sse2 ) cpu_flags_x86_sse2 ? ( cpu_flags_x86_sse ) "
Could you please submit those logs so I can recheck?

@Hector Martin Thanks for the hint! Was a bug in my /etc/portage directory (never set CPU_FLAGS_X86 twice without appending the old string). @Amy Liffey Log from 3.4.1-r1, but had the same problems with 3.4.1, and AMD64 instead of X86.
@Hector Martin, I have gentoo installed on a virtualbox guest. The host supports popcnt and sse4_2 but virtualbox propagates sse4_2 only. I think it is a bug in virtualbox. Here is the host cpu flags: flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm pti tpr_shadow vnmi flexpriority ept vpid dtherm ida And the virtualbox guest: flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx rdtscp lm constant_tsc rep_good nopl xtopology nonstop_tsc cpuid pni ssse3 sse4_1 sse4_2 hypervisor lahf_lm pti My point is you could have sse4_2 but not popcnt.
Maybe the ebuild should set: -DOPENCV_CPU_OPT_IMPLIES_IGNORE=ON instead? Since their checks are somewhat too strict in certrain cases (e.g. FMA3 implies AVX2, but there are AMD CPUs -Piledriver- out there with FMA3 support but without AVX2)
I have something similar, except it's saying I don't have FMA3 on Bulldozer (FX-8350) which I know does have it. See my logs.

Exactly the same as above on AMD Phenom(tm) II X4 945 Processor.
And it happens for opencv-3.4.1-r2 too.
And it happens with a AMD Phenom(tm) II X4 965 Processor.
(In reply to Juergen Rose from comment #25) > And it happens for opencv-3.4.1-r2 too. Yes it does because I did not fix it yet. Give me few days pls

Add "-DOPENCV_CPU_OPT_IMPLIES_IGNORE=ON" to "GLOBALCMAKEARGS". This single change allows me to compile opencv-3.4.1-r2 on Piledriver without giving up FMA3 or any other CPU flag, which goes to show that those "dependencies" are just a failed attempt at doing some automagic configuration.

Would you mind to provide tested patch for the ebuild? Thank you

Unfortunately, this breaks the build on AMD Piledriver because FMA3 implies AVX2 which is not available on this architecture. Further more, these CPU flags should only be handled by the corresponding Portage flags, instead of CMake's hard-coded automagic. This commit fixes that by disabling the whole "implication" mechanism for CPU flags, while also undoing the previous attempt at solving the problem by translating those broken "implications" into REQUIRED_USE.
