<div dir="ltr">Hi,<div><br></div><div>Thank you! Yes it is 3.7</div><div> Indeed I found that there was a 'use mpi' somewhere in the tree of modules called.

Looks like mpif.h is getting included in some module that your code<br>
is currently using.<br>
<br>
Is this module your code - or petsc code?<br>
<br>
Is using mpi via module [perhaps mpi.mod is preferable over mpif.h] -<br>
then you can do something like:<br>
<br>
#define PETSC_AVOID_MPIF_H<br>
#include <petsc/finclude/petsc.h90><br>
