I get the below compiler warning in Visual Studio C++ Community 2015 with Eigen linear algebra library version 3.3.2:

eigen\src/Core/util/Macros.h(815): warning C4668: 'CUDACC_VER' is not defined as a preprocessor macro, replacing with '0' for '#if/#elif'

I resolved it by replacing
"__CUDACC_VER__ " with "defined(__CUDACC_VER__)" on line 815 of Macros.h

so the new line 815 is now:

Code: Select all

#if EIGEN_COMP_MSVC_STRICT && (EIGEN_COMP_MSVC < 1900 ||  defined(__CUDACC_VER__))

I am not familiar enough with programming to know if this is a bug I should submit, or if I am doing something wrong, so wanted to ask here first before logging it as a bug.

this has been fixed in 3.3.3
