[Openmp-dev] Math symbols are not found during configuration

[Doerfert, Johannes via Openmp-dev]

Hi Itaru,

For now, you need to define them yourself when you need them in the target region.
We are working on a permanent solution.

Thanks,
  Johannes

Hi,
Adding the flag -fopenmp-targets=nvptx64 makes math symbols M_E and M_PI defined in cmath not detected during the execution of CMake. How do I work around this? I am using the latest trunk Clang at this moment, and without the above flag, both symbols are detected properly.

Thanks,
Itaru.
