OpenCV 2.4.3 Meets SSE4 Instruction blendvpd in Intel CPU E5200 whice causes "Illegal Instruction"

edit

Thanks for your reply. I built OpenCV using CMake, and I can see ENABLE_SSE, ENABLE_SSE2 in configuration, but where to disable SSE4?

ENABLE_SSE and ENABLE_SSE2 does not control compiler optimizations. It enables and disables pieces of optimized with SSE intrinsics or in-line assembler code. If you use Visual Studio for OpenCv build, open OpenCV project properties Select C++ -> Optimisations and select supported instruction set. I do not remember exact field name, but there is list of instruction sets: no optimizations, SSE, SEE2, etc. If you use GCC compiler, then it builds library with optimizations supported by your hardware by default.

Hi Alexander, thanks! And I found the solution in another thread http://answers.opencv.org/question/4694/0xc000001d-illegal-instruction-when-running/
