I got exactly same thing here following installation guide. Any solution for this one?

Godricly commented 8 years ago

well. I copied .cpp as .cu and it passed. Not sure if this is right approach. The icon of .cu file stands for a link? both tests are passed.

Got the same issue. The following solution helped me. Add these CXX compilation flags to the CMakeLists.txt: -D_MWAITXINTRIN_H_INCLUDED -D_FORCE_INLINES -D__STRICT_ANSI__

gcc5 is not supported in CUDA 7.5. Will you try again with CUDA 8.0? It appears CUDA 8.0 supports Ubuntu 16.04 with gcc 5.3.1.
