[petsc-users] running error

[paul zhang]

Hi Jed,

Now I see PETSc is compiled correctly. However, when I attempted to call
"petscksp.h" in my own program (quite simple one), it failed for some
reason. Attached you can see two cases. The first is just the test of MPI,
which is fine. The second is one added PETSc, which has segment fault as it
went to

        MPI_Comm_rank (MPI_COMM_WORLD, &rank);        /* get current
process id */

Can you shed some light? The MPI version is 1.8.3.

Thanks,
Paul
