This is fixed by "make linux-x86-64-avx". Great. You should indeed be using these -avx and -xop targets where appropriate. However, if a C compiler happens to have AVX (or even XOP) enabled by default, that should not prevent other make targets from working. So I might try to reproduce your build errors later. For now, my guess remains that the targets would in fact work if -march=native were implied, but did not work because you somehow modified the CFLAGS in this way for _some_ source files only. I simply have no other explanation, although of course this guess might be wrong. > Sorry for decreasing the signal to noise ratio on the list. You did not. Thanks, Alexander
