If I use the following CFLAGS, I don't get the error: CFLAGS="-march=westmere -O2 -pipe -maes -msse4.2 -mavx" Since I use distcc, I don't use -march=native. However, the flags listed in the output of emerge --info are those that would be selected by -march=native.
Are you building chromium with USE="custom-cflags"? Please attach a build log.
As I said, I use distcc, so I set the same CFLAGS as those that would be selected by -march=native (as explained here: https://wiki.gentoo.org/wiki/Distcc/fr#-march.3Dnative). I am restarting a build with these cflags to get a fuild build log containing the error.
Created attachment 411554 [details] full build log So here is the full build log. And I don't use custom-cflags.
Ok, so we probably need to filter some additional -mno-xxx flags. Here's what we currently have: # Avoid CFLAGS problems, bug #352457, bug #390147. if ! use custom-cflags; then replace-flags "-Os" "-O2" strip-flags # Prevent linker from running out of address space, bug #471810 . if use x86; then filter-flags "-g*" fi # Prevent libvpx build failures. Bug 530248, 544702, 546984. if [[ ${myarch} == amd64 || ${myarch} == x86 ]]; then filter-flags -mno-mmx -mno-sse2 -mno-ssse3 -mno-sse4.1 -mno-avx2 fi fi I will have to review the log to find what we are missing.
I was hit by this too (compile failed at libvpx). For me removing -mno-avx from CFLAGS fixed it. (Had it there because of legacy problems with gcc-4.4 and sandybridge) Failing CFLAGS: CFLAGS="-march=native -O2 -pipe -mno-avx" Successful CFLAGS: CFLAGS="-march=native -O2 -pipe"
