What I see is that ATLAS is not able to detect the type of system on which it is running. My first question then is: * Are we corss-compiling, or are we on proper hardware? If we are cross-compiling, then the only solution that I see it to try to fix the configuration with parameters passed to configure and give up on optimization. I have no practical experience with MIPS, so my next question is: In the list of architectures supported by ATLAS I see: 49 = 'MIPSR1xK' 50 = 'MIPSICE9' Is one of the two appropriate? Also ATLAS wants to know about ISA extensions. Is any of the following relevant or should I pick 'none'? none: 1 VSX: 2 AltiVec: 4 AVXMAC: 8 AVXFMA4: 16 AVX: 32 SSE3: 64 SSE2: 128 SSE1: 256 3DNow: 512 NEON: 1024 Regards, Fede P.S.: I'm indeed not subscribed to the bug list. Could you copy me directly?
