build log for a ryzen5 cpu
The complcation is that I travelled to the work dir & bootstrapped the file,compiled and there were no error messages & it compiled up just fine. /bin/sh ../../../libtool --tag=CC --mode=compile x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I/var/tmp/portage/sci-libs/fftw-3.3.8/work/fftw-3.3.8/dft/simd/avx2 -I../../.. -I /var/tmp/portage/sci-libs/fftw-3.3.8/work/fftw-3.3.8 -march=core-avx2 -mfma -O2 -march=athlon64 -pipe -c -o n1fv_10.lo /var/tmp/portage/sci-libs/fftw-3.3.8/work/fftw-3.3.8/dft/simd/avx2/n1fv_10.c Note that -march=athlon64 appears there which trumps the previous -march=core-avx2. athlon64 does not have AVX2. Fix your CFLAGS.

Fix your CFLAGS. noted and have changed it to native as there does not appear to be an alternative for the ryzen series cpu's Created attachment 548164 [details]
