Hello, Yes my examples work fine. I have looked in the makefile for the examples and it looks fairly complicated. One thing I noticed is that I wasn't using the mpicc that is in my petsc directory. I went back and made sure that I am using the mpicc that was build by PETSc. That changes things, but now I cannot compile the code whereas before I could.
Do you have a suggestion as to how I can most easily adapt the makefile from the examples into the code we are building?
