OK, I see the problem. You were right that we weren't picking up libdevice. CUDA 7.0 only ships with the following libdevice binaries (found /path/to/cuda/nvvm/libdevice): libdevice.compute_20.10.bc libdevice.compute_30.10.bc libdevice.compute_35.10.bc If you ask for sm_50 with cuda 7.0, clang can't find a matching libdevice binary, and it will apparently silently give up and try to continue compiling your program. That's a bug that we should fix. (If you want the current behavior, you should have to ask clang not to use libdevice...

Hi Justin, Thanks for your response! The clang & llvm I'm using was built from source. Below is the output of compiling with -v. Any suggestions would be appreciated! *clang version 3.9.0 (trunk 270145) (llvm/trunk 270133)* *Target: x86_64-unknown-linux-gnu* *Thread model: posix* *InstalledDir: /usr/local/bin* *Found candidate GCC installation: /usr/lib/gcc/x86_64-linux-gnu/4.8*

Hi, Yuanfeng. What version of clang are you using? CUDA is only known to work at tip of head, so you must build clang yourself from source. I suspect that's your problem, but if building from source doesn't fix it, please attach the output of compiling with -v.
