This is petsc-3.7? Looks like mpif.h is getting included in some module that your code is currently using.
Is this module your code - or petsc code? Is using mpi via module [perhaps mpi.mod is preferable over mpif.h] - then you can do something like: #define PETSC_AVOID_MPIF_H #include <petsc/finclude/petsc.h90> Satish On Tue, 31 Jan 2017, Timothée Nicolas wrote: > Dear all, > > I am a bit confused as to how to link PETSc correctly in a code that > already uses MPI natively.
