[petsc-users] Petsc with open mpi 1.7

[Suraj Prabhakaran]

yes I also observed that. But still when I link petsc to a simple hello world example, I can see that the binary requires libmpi_f77 and libmpi_f90.
Can you please compile the following snippet with mpicc and link it with petsc library, do a ldd on the binary and see if it asks for these 2 libraries or not?

#include "stdio.h"
int main()
{
printf("hello world\n");
return 0
}

best,
Suraj
