Yes, as I told you out of make file, it works. The problem is something strange in the make file. I tested many different ways again, like adding all parameters from "mpif9- --showme" to the make file. Again , it does not work. I really don’t understand what the problem is. any other suggestion?? > mpif90 my_application.f90 -o my_application --showme > Also make sure of two things: > 1. The mpif90 is the one you think it is (e.g., run "which mpif90" and ensure > that you're getting the "right" mpif90) >2. Ensure that your Open MPI has f90 support compiled in. Run "ompi_info | >grep -i fort" and look at the output to ensure that your OMPI installation >>has F90 support compiled in. I tested both of them. They seem good.
