Cool, then you are probably the a person who is able to answer this question: What is a good way to mix C++ and Fortran build environments? Is there a way to mix the PrgEnv-{Cray/PGI} so that I can compile C++/CUDA code with GCC 5.x/6.x and the Fortran code in OpenACC mode with PGI/Cray?

Right now, we have quite a elaborate build environment where we first load the GCC build environment to compile the C++ code base. Then we load a Fortran build environment to compile the Fortran code base. I would rather have to use one environment to work in. In the most recent Cray and PGI environments (6.0.3) I have to also add the linker path to GCC version I used for C++. This is to avoid linker issues with the C++11 abi in the newer GCC compilers (somehow, the Cray/PGI environment always wants to link with old GCC libraries). Its not a big problem with our build scripts but annoying nevertheless.
