[petsc-users] Error "Attempting to use an MPI routine before initializing MPICH" after compiling PETSc with Intel MPI and GCC

[Roland Richter]

Hei,

the following code works fine:

#include <iostream>
#include <petsc.h>

static char help[] = "Solves 2D Poisson equation using multigrid.\n\n";
int main(int argc,char **argv) {
    PetscInitialize(&argc,&argv,(char*)0,help);
    std::cout << "Hello World\n";
    PetscFinalize();
    return 0;
}

Regards,

Roland
