Compiling the latest mplayer I noticed this message...
Checking for kernel support of avx2 ... failed
My processor supports avx2 so I looked at the configure script. The problem seems to be with the line...
extcheck $_avx2 "avx2" "vextracti128 $0, %%ymm0, %%xmm0"
$0 is replaced with the script name, resulting in a test program with the line...
__asm__ volatile ("vextracti128 ./configure, %%ymm0, %%xmm0":::"memory"); return 0;
Escaping $0 solves the problem.
extcheck $_avx2 "avx2" "vextracti128 \$0, %%ymm0, %%xmm0"
I Googled this but found no relevant results. Just wondered if this is a known problem?
