WW3 compilation issues (regarding open mpi)

[fakaaaaaaaa12]

Hello, I am trying WW3 about OASIS3-MCT5.0 interface production, at present there are more problems, but the main problem is that I have different compilers when I do the compilation of the two, which leads to more problems, at present, the online tutorials on the installation of WW3 are basically all Gnu compilation, but I want to use mpirun (Open MPI) 4.0.3 for the compilation, may I ask, in addition to the comp and the I want to compile with mpirun (Open MPI) 4.0.3, do I need to do anything other than modifying the comp and link files, and how do the comp and link work? (There are indeed a lot of header file examples to refer to, but would like to hear your advice)
