My system is a build farm for several others systems, thus I can't use -march=native. I think the following configure option could help : > AC_ARG_ENABLE([simd], AS_HELP_STRING([--disable-simd], [Disable SIMD code.

This will really need proper fixing to expose each of the SIMD options as configure options because otherwise --disable-simd won't even work if you put the right stuff in CFLAGS. See e.g. https://github.com/sekrit-twc/zimg/blob/4ad3eff769fcaa10a64083dddb74457e8e46f069/configure.ac#L80.
Unable to install/upgrade-to media-video/handbrake stable 1.4.2-r2 because of this.

Because of AX_CHECK_COMPILE_FLAG⁽¹⁾, this would build AVX code into media-libs/zimg package. This would crash potentially any reverse dep ⁽²⁾ on any system who do not handle AVX instuctions set. My CPU is having AVX instructions set support, but other gentoo systems on which I deploy tbz2 packages don't. 1. https://github.com/sekrit-twc/zimg/blob/master/configure.ac#L85 2. https://packages.gentoo.org/packages/media-libs/zimg/reverse-dependencies

I will try this asap and report here, but, where does this option comes from ?
I was able to build media-libs/zimg-3.0.1 with : > > EXTRA_ECONF="--disable-simd" emerge -av1 media-libs/zimg However I hitted another build failure in bug #832201.
(In reply to Fab from comment #9) > I was able to build media-libs/zimg-3.0.1 with : > > > > EXTRA_ECONF="--disable-simd" emerge -av1 media-libs/zimg Still the same with media-libs/zimg-3.0.4.
