Hi galaxy001,

CUDA is being used to write the GPU runtime library, and it is known that the CUDA libraries are not prepared to have clang as the host compiler. There is a pull request by hanjo being reviewed to avoid that, and just fail producing that library. We are just evaluating the impact of that change in some other platforms. In the meantime you can try nvcc to use gcc (if you have it) for the host compiler.

Thanks for reporting the issue! Samuel
