Mohamed,
These are missing library symbol errors. I suspect that you need to
add this to the top of each program unit that has Netcdf calls:
use netcdf
This is because the Netcdf Fortran 90 interface uses modules. You
can't properly link to the Netcdf F90 library without this declaration.
For diagnosis, your program is trying to link to this:
__netcdf__nf90_open
But with a correct "use" statement it should be seeking a symbol
named something like this (the name change may vary by compiler and
platform):
___netcdf_MOD_nf90_open
I might be wrong about all of this if you are on a platform or
compiler that uses Fortran 90 linking conventions much different
than what I am familiar with. If "use" doesn't fix it, then please
provide identification and version info for your platform, compiler,
and netcdf version.

Any ideas?
