[petsc-users] PETSc + Cray MPICH Build Error in User Code

[Mancinelli, Asher J]

Hello all,

We are attempting to build an application that relies on PETSc with Cray MPICH, and we're encountering the following build-time error:

#    error "PETSc was configured with MPICH but now appears to be compiling using a non-MPICH mpi.h"
     ^

I've replaced some possibly sensitive paths with text in angle brackets for a description, eg <cray-mpich prefix>.

Is this a known issue? Is it apparent from this text that we're doing anything wrong?
