Description Pieter Noordhuis 2017-08-23 15:48:32 UTC

In the recently released CUDA 9 RC, the __CUDACC_VER__ macro is deprecated. It is set to an error string, so it will cause compilation errors. The recommended macro's to use are __CUDACC_VER_MAJOR__, __CUDACC_VER_MINOR__, and __CUDACC_VER_PATCH__.

I worked around this problem by #undef'ing the error string macro and resetting it to behave as it previously did. Ideally this is addressed in Eigen itself though.

I verified this is a problem in 3.3, but see the macro is still used in trunk.
