I want to build MUMPS through PETSc and don’t really care about the Fortran PETSc interface on our Windows boxes (--with-fortran-interfaces=0).

I think you want --with-fc=0, which should turn off this check.

No, I have gfortran, I want to compile MUMPS with PETSc, that won’t work --with-fc=0. Also, the error message in the configure is wrong, it should read "PETSc Fortran bindings” (not “fortran interface”), and in my email, one should replace --with-fortran-interfaces by --with-fortran-bindings, sorry about that. I guess there is a missing check before raise RuntimeError('mpi.mod not found! PETSc fortran interface requires a working mpi.mod'), like if self.argDB['with-fortran-interfaces'] But I don’t know if that makes sense.

I guess you mean: diff --git a/config/BuildSystem/config/packages/MPI.py b/config/BuildSystem/config/packages/MPI.py index 7ea2716cc5..5a1baff9f9 100644 --- a/config/BuildSystem/config/packages/MPI.py +++ b/config/BuildSystem/config/packages/MPI.py @@ -497,7 +497,7 @@ Unable to run hostname to check the network') def FortranMPICheck(self): '''Make sure fortran include [mpif.h] and library symbols are found''' - if not hasattr(self.compilers, 'FC'): + if not hasattr(self.compilers, 'FC') or not self.argDB['with-fortran-bindings']: return 0 # Fortran compiler is being used - so make sure mpif.h exists self.libraries.pushLanguage('FC') If MS-MPI is missing mpi.mod - I guess we'll have to revert this requirement. For some reason the tests in CI don't error out. I'll have to check. I can add back mpif.h usage [without the extra complex code we had for handling some corner cases - in this mode] Satish

Yet, I’m now hit by: ******************************************************************************* UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details): ------------------------------------------------------------------------------- mpi.mod not found! PETSc fortran interface requires a working mpi.mod ******************************************************************************* Could this be fixed somehow, please? Thanks, Pierre
