It can't be this easy, but you don't really have "mpi_init()" in the code
right? It's "MPI_Init()".
Probably it's something more tricky than this, but I had to make sure.

Hi,
We am having trouble linking to the mpi library for a code which is not
FLASH. These same linker lines work for our FLASH code so we are a bit
stumped.
Our LD line and error messages are below.
Thanks for any help,
