[petsc-users] conflict between petsc.h90 and MPI_INT, MPI_SUM etc...

Tue Jan 31 10:26:34 CST 2017

Hi,

Thank you! Yes it is 3.7
 Indeed I found that there was a 'use mpi'  somewhere in the tree of
modules called. I could break the module apart without great difficulty, so
that I don't call mpi anymore in the affected portion of the code. It looks
like it indeed fixes the issue. But it's also nice to give me the other
solution with PETSC_AVOID_MPIF_H, which could have been very useful if I
hadn't been able to easily break the module apart.

Cheers

Timothee
