I installed nsight with cuda5.5. Everything works fine but I am trying to run opencv functions on the host to generate images. I include opencv header path and also the libs paths that I need. When I try to compile it gives this error /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/5.0/include/emmintrin.h(274): error: identifier "__builtin_ia32_cmpsd" is undefined Anyone knows what could be the reason? Or any way to have make opencv work with nsight eclipse? Thanks!
- 6I don't think that your error depends on cuda or opencv. For me it seems to be problem with clang. Propably it's only missing a linked library from there.hubs– hubs2013-11-29 13:11:54 +00:00Commented Nov 29, 2013 at 13:11
- 2I would second @hubs in that this looks like OpenCV issue with Clang.Eugene– Eugene2013-12-02 19:29:20 +00:00Commented Dec 2, 2013 at 19:29
- @hubs How did you solve your problem?Rose Perrone– Rose Perrone2014-05-26 02:39:59 +00:00Commented May 26, 2014 at 2:39
- @RosePerrone I didn't solve this problem. I wanted only to note, that this problem doesn't relate to nsight eclipse, cude or opencv. I think there is missing a link against a clang library.hubs– hubs2014-05-26 13:06:21 +00:00Commented May 26, 2014 at 13:06

I solved my issue by removing the '-D HAVE_SSE2' from the macros defined in config.mk.
If you can't do that:
See this solution. In brief, you need to compile the code using SSE2 using gcc and your CUDA code using nvcc and then link them together afterwards.
Apparently NVidia is aware of the problem and "it should be fixed soon", but I have v6.0 and the bug still exists.
Someone mentioned this problem on the NVIDIA developer forums, but nobody replied.
