<div>I am trying to call Petsc from a C++ program and having difficulties. I'm using v3.2.6 and I can run all the examples so I assumed that everything was installed ok. The body of the function is very simple, see below. I get a segmentation fault. In my installation I used mpich<br>

I have a colleague who also installed openmp and this works for him on the same version of Petsc. Could it be that Petsc is confused because I have two different MPI's installed? I am hoping that it will use the one that it configured but I do have the other MPI in the same path.</div>
</blockquote></div><br><div>Yes, the most likely scenario is that your application was linked with a different MPI than PETSc was compiled with. It is probably a makefile that uses the wrong MPI. Can you build PETSc examples?</div>
