There is one other thing you should be aware of. --enable-simd=avx will only run on processors that support AVX. If you force a build to use AVX and your OS an processor don't support it you will get an error. In theory you shouldn't need --enable-simd=avx for do it yourself builds, as the 1.02.000 build process will attempt to use AVX during compile if supported on your OS and processor. If AVX isn't supported it will use SSE or SSE2, and if the processor doesn't support any of them then it will use none. Unless you are experiencing problems, you shouldn't need --enable-simd=avx . So this should work: ./configure CC="gcc49" CPPFLAGS="-O3 -funroll-loops -march=native -mtune=native -I/usr/local/include" LDFLAGS="-L/usr/local/lib" -- Michael Petch GNU Backgammon Maintainer / Developer OpenPGP FingerPrint=D81C 6A0D 987E 7DA5 3219 6715 466A 2ACE 5CAE 3304 _______________________________________________ Bug-gnubg mailing list Bug-gnubg@gnu.org https://lists.gnu.org/mailman/listinfo/bug-gnubg
