Compilation problems on

[Reiner Vogelsang]

Hello,
how does link statement look like?
Moreover, you can check by yourself if the MPI library
contains MPI-I/O.

nm -no <the mpi library> | fgrep -i MPI_File_open

How does the symbol for MPI_File_open look like?

BTW, I am not familiar with the installation at NCAR.
So, please be  more specific on the type of machine and
OS your are working on.

Best wishes
