I am trying to use SSE2 intrinsic instructions to do double precision operations. I am unable to compile the code with GCC however. I was wondering what to do to get it to compile. My code compiles in windows Intel compiler just fine. I've searched the Internet and have yet to come up with something useful. I'm running GCC4.0.2 on Windows. I'm a very much a noob here. My GCC environment was set up by another guy that is since gone. I'll be happy to provide more details, just not sure what that would be. I have: #include "emmintrin.h" … __m128d m_Isa64Src0; m_Isa64Src0 = _mm_set_pd(0.0, m_Src[0][Element].FloatData); And get these errors: : error: '__m128d' does not name a type : error: 'm_Isa64Src0' was not declared in this scope Thanks, Darin
