Created attachment 555458 [details] media-libs:libaom-1.0.0-r1:20181117-122721.log aom_dsp/x86/jnt_sad_ssse3.c doesn't get built with this combination of USE flags.
Stumbled upon this bug compiling my own _very_ 64-bit genric distribution for a future LiveDVD (and/or netboot...) with march=x86-64 and mtune=k8 BUT with disabled 3dNow! (-mno-3dnow -mno-3dnowa) in order to support even the early 64-bit VIA processors with very few extra instruction-sets... However, looking at the ebuild, it seems to handle the CPU-flags internally within multilib_src_configure(). BUT adding '-DAOM_TARGET_CPU=generic' (as suggested at https://github.com/mozilla/aom/issues/2) at the bottom of these options seems to help compiling, working here in my local overlay. Realizing that this is NOT the real solution on how to solve the ebuilds internal CPU-flags logic, but it might help pointing someone who knows what (s)he's doing in the right direction.. Cheers! /Charlie
I get a similar error, but I have all the sse variants enabled in make.conf: sse, sse2, sse2, and sse4a. And I get more error messages: libaom.so.0: undefined reference to `aom_sad4xh_sse2' libaom.so.0: undefined reference to `aom_sad16xh_sse2' libaom.so.0: undefined reference to `aom_sad64xh_sse2' libaom.so.0: undefined reference to `aom_sad8xh_sse2' libaom.so.0: undefined reference to `aom_sad32xh_sse2' libaom.so.0: undefined reference to `aom_sad128xh_sse2' I'll attach the build.log.

i got passed this bug by migrating my processor use flags to the new CPU_FLAG_X86 symbol as prescribed in the gentoo wiki article of the same name.

Do you mind sharing the link or shedding more light on this issue? I'm hit with the same bug and I can't get passed it to compile the latest firefox. Thanks in advance!

(In reply to Kelly Hirai from comment #4) > i got passed this bug by migrating my processor use flags to the new > CPU_FLAG_X86 symbol as prescribed in the gentoo wiki article of the same > name. Not sure how that fixes the problem. I have the same specified in both areas and it still fails to compile on one of my machines.
(In reply to Matthew Schultz from comment #6) > https://wiki.gentoo.org/wiki/CPU_FLAGS_X86 So yeah, I also had these set and it doesn't help, I get the 'undefined reference' errors. I thought Kelly meant something related to this: https://wiki.gentoo.org/wiki/CPU_FLAGS_X86_conversion https://packages.gentoo.org/useflags/cpu_flags_x86_xop
Also possibly of relevance, the machine I have that successfully compiled and installed libaom-1.0.0 has every CPU_FLAGS_X86 flag enabled while the machine that is not able to compile it has the following: CPU_FLAGS_X86="mmx sse sse2 sse3 -avx -avx2 -sse4_1 -ssse3"
Its working for me after $ cpuid2cpuflags CPU_FLAGS_X86: aes avx mmx mmxext pclmul popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3 and then putting CPU_FLAGS_X86="aes avx mmx mmxext pclmul popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" in /etc/make.conf.
Yes, this solved it for me: CPU_FLAGS_X86="aes avx mmx mmxext pclmul popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" turned out to be that by mistake I set CPU_FLAGS_X86 twice in my make conf, and the latter did not include all the flags... <facepalm>

After testing this a bit more, it seems to fail consistently on my older machines which run AMD cpus with the aforementioned CPU_FLAGS_X86 set. No other CPU_FLAGS_X86 can be set on these older CPUs because they aren't supported. In addition, this appears to be an amd64 arch problem because it compiles fine on my opteron 144 running x86 arch.
This bug also hits not so old AMD (Phenom II) CPUS. The make.conf has: CPU_FLAGS_X86="3dnow 3dnowext mmx mmxext popcnt sse sse2 sse3 sse4a", but I still get the same errors as Comment 2.
On my AMD Phenom II X6 , emerge libaom-1.0.0-r1 1) Fails with "+sse2" CPU_FLAGS_X86="3dnow 3dnowext mmx mmxext popcnt sse sse2 sse3 sse4a" 2) Succeeds with "-sse2" CPU_FLAGS_X86="3dnow 3dnowext mmx mmxext popcnt sse sse3 sse4a" Full cpu flags (from 1) i got from cpuid2cpuflags
Fixed emerge by setting full CPU_FLAGS_X86 in make.conf and adding "media-libs/libaom -cpu_flags_x86_sse2" to the package.use Had compile problems on AMD Phenom II X6 Compile on Intel i7-4771 was ok without any changes (switched to CPU_FLAGS_X86 on both systems long ago)
Can emerge by changing make.conf ABI_X86= to "64", but not "32" or "32 64". "32" and "64 32" errors out with the same error as comment 2. "64" gives a post compile warning message of: QA Notice: Package triggers severe warnings which indicate that it * may exhibit random runtime failures. * /var/tmp/portage/media-libs/libaom-1.0.0-r1/work/av1/encoder/rdopt.c:8263:51: warning: array subscript -1 is below array bounds of ‘const CANDIDATE_MV[8]’ {aka ‘const struct candidate_mv[8]’} [-Warray-bounds] As comment 15, compiles fine on Intel Atom Cherry Lake and Intel i7 gen 7 chips. No such luck on AMD Phenom II 965. Tied into Bug 678160?

Just ran into this, looks like upstream issue, but I'm a cmake n00b. I haven't tested the resultant binary but this at least this patch allows build: --- work.orig/aom_dsp/aom_dsp.cmake 2018-06-28 09:19:27.000000000 -0600 +++ work/aom_dsp/aom_dsp.cmake 2019-09-19 09:33:08.756420455 -0600 @@ -183,6 +183,7 @@ "${AOM_ROOT}/aom_dsp/x86/highbd_variance_sse2.c" "${AOM_ROOT}/aom_dsp/x86/quantize_sse2.c" "${AOM_ROOT}/aom_dsp/x86/sum_squares_sse2.c" + "${AOM_ROOT}/aom_dsp/x86/jnt_sad_ssse3.c" "${AOM_ROOT}/aom_dsp/x86/variance_sse2.c") list(APPEND AOM_DSP_ENCODER_ASM_SSSE3_X86_64 @@ -208,8 +209,7 @@ "${AOM_ROOT}/aom_dsp/x86/masked_sad_intrin_ssse3.c" "${AOM_ROOT}/aom_dsp/x86/masked_variance_intrin_ssse3.h" "${AOM_ROOT}/aom_dsp/x86/masked_variance_intrin_ssse3.c" - "${AOM_ROOT}/aom_dsp/x86/jnt_variance_ssse3.c" - "${AOM_ROOT}/aom_dsp/x86/jnt_sad_ssse3.c") + "${AOM_ROOT}/aom_dsp/x86/jnt_variance_ssse3.c") list(APPEND AOM_DSP_ENCODER_INTRIN_SSE4_1 "${AOM_ROOT}/aom_dsp/x86/highbd_variance_sse4.c" With this patch I was able to build without SSSE3 enabled and it appears to not affect my machine with SSSE3. As this patch is written, people with SSSE3 instructions must also enable SSE2 because I'm a cmake n00b and don't know a better way to do this (is it okay to duplicate files in the cmake file?). Again I have not tested the resultant binaries so more testing is needed, the machine that I need to test on is currently building rust so it needs to be undisturbed for a while...
On a machine with cpuid2cpuflags with output of CPU_FLAGS_X86: aes avx f16c fma3 fma4 mmx mmxext pclmul popcnt sse sse2 sse3 sse4_1 sse4_2 sse4a ssse3 xop and CPU_FLAGS_X86 to exactly this makes it work. It seems like the combination of avx and the more recent sse4*/ssse do the trick. Didn't need to apply a patch.
Correct, newer machines that have SSSE3 set (will have SSE2 as well) and will thus build properly. Only the older target machines that have SSE2 but not SSSE3 will have problems. Or if you typo SSE3 instead of SSSE3...
Just wanted to follow up that the machine with SSE2 but not SSSE3 was able to build and run libaom with the patch. I tried using it with ffmpeg-4 to encode av1 streams, it at least does not give me illegal instructions but could not discern if the program was working completely (the webpages I read about how to use ffmpeg to build av1 gave me this huge disclaimer about how slow it is, and I do witness the extreme slowness of using libaom compounded with the fact it's running on an old P4.) www-client/firefox-68.1.0[system-av1] seems to build/run fine with the patched libaom, but I don't have any av1 streams to test playback against.
I have had yet no chance to check if the compiled binary actually functioning correctly (updated my ws from a mobile device while travelling abroad with almost no internet access) but I can confirm that the patch from comment #21 at least allows libaom to compile and link. K8 CPU with SSE2, SSE3 but not SSSE3, CPU_FLAGS_X86="3dnow 3dnowext mmx mmxext sse sse2 sse3".
I can confirm libaom 1.0.0-r2 builds with the following flags set: # grep CPU_FLAGS /etc/portage/make.conf CPU_FLAGS_X86="mmx mmxext popcnt sse sse2 sse3 sse4a" # grep libaom /etc/portage/package.use/default media-libs/libaom -cpu_flags_x86_sse2 # gentoo bug #6713401 The machine is a VM running on AMD Epyc HW. Without the SSE2 flag disabled for the package the build fails with the above mentioned linker errors.

adding "media-libs/libaom -cpu_flags_x86_sse2" to package.use fixed it for me as well cheers

Created attachment 664903 [details, diff] /etc/portage/patches/media-libs/libaom/cpuflags.patch rebased to media-libs/libaom-2.0.0 Atthached is the patch from comment #21 rebased to version 2.0.0. I didn't do any encoding though but decoding seem to work on my setup (see comment #25).
media-libs/libaom-2.0.0 failed to build for my sse2 (no sse3) CPU intel core-i3 550 with CPU_FLAGS_X86="sse2" and successfully merged with CPU_FLAGS_X86="-sse2".
Same problem. Same solution - I excluded sse2 from CPU_FLAGS_X86="mmx mmxext sse sse3" and libaom compiled.

This one is supposedly fixed in 3.0.2 according to https://gitlab.com/webmproject/libaom/-/blob/master/CHANGELOG.
