problem with mpich-gcc7 on mojave

[ogourgue (Olivier Gourgue)]

I recently migrated from high sierra to mojave flooding the migration procedure described on MacPorts website.

The procedure went to the end, but I got strange warnings for mpich-gcc7. So I uninstalled, cleaned and reinstalled the port. The warnings were still there:

The problem is that using mpich-gcc7 is not working neither. I got the following error messages:

I hope you can help me solve the problem.

I guess my first question would be do you need mpich-gcc7, or would mpich-default work for you? I'll try to take a look at it when I have time.

I think the warnings are harmless and related to the dropping of i386 support on Mojave.

[eborisch (Eric A. Borisch)]

I will definitely need more info. I can compile and run a simple MPI program (with some communication between ranks) with mpich-gcc7 on Mojave. Granted, I'm running only locally.

[ogourgue (Olivier Gourgue)]

I decided to switch to openmpi-default for all my mpi applications and it works fine. Unfortunately, I don't have time for the moment to look at my mopish-gcc7 for the moment. I hope I can come back to it later and let you know.
