I see -mavx2 has been added at the compile lines, which is not desired
This ebuild needs flag-o-matic in order to build libraries for all features. Those features are tested and eventually executed at run-time.
Created attachment 767179 [details, diff] patch for the ebuild Added flag-o-matic to remove some CFLAGS (-mno*)
Yeah, it does seem to have runtime detection, so I guess that's good enough.
Created attachment 767223 [details, diff] patch for the ebuild -v2 this patch is based on all flags enabled in the makefiles
Created attachment 767248 [details, diff] patch for the ebuild -v2a oops...
I have a similar issue with "-mno-avx512*" and with the above patch, I could properly compile the package. I modified the filter-flags line to "-mno-avx*" to catch all the avx flags.
