Folks, this is great news indeed ! unfortunately, the current status is not quite good right now :-( I reported my findings to the (GNU) fortran ML, and you can read this at https://gcc.gnu.org/ml/fortran/2019-04/msg00013.html Cheers, Gilles On 4/3/2019 9:59 AM, Raffenetti, Kenneth J. via devel wrote:
It's great to hear this feature will land in GCC! I will test it out and report back.

The upcoming GCC 9 release will contain the first version of gfortran that provides the Fortran 2018 ISO_Fortran_binding.h header file, which MPICH requires in order to build MPI 3's mpi_f08 module. If anyone is interested in testing, please checkout the current GCC trunk and submit any related issues to the gfortran developers at [email protected] <mailto:[email protected]>. Alternatively, if its easy to explain how to run any related tests in the MPICH test suite, please let me know. So far, I have verified that mpi_f08.mod gets installed when MPICH is built with a recent checkout of the gfortran trunk.
I'm cc'ing Paul Thomas, who contributed the ISO_Fortran_binding patch to gfortran under contract for Sourcery Institute.
