MPICH does not currently provide the mpifort_abi library and compile wrapper. I’ve created an issue to note this and track progress on implementation for the next major release. Thanks for the question/report.

<pre><div style="white-space: pre-wrap; font-family: sans-serif;">Hi,
Does mpich 5.0.0 support the full MPI ABI standard ? I see it creates
mpicc_abi which links against libmpi_abi, but no equivalent mpifort_abi.
Is this planned?
Best regards
Alastair
