Howdy Dimitra!

Since you are building with the intel compiler, you will want to read their web
page on building netCDF with ifort:
http://www.intel.com/support/performancetools/sb/CS-027812.htm

But the problem you are having may be even more basic than incorrect flag
setting. Take a look at the config.log file that was generated when you ran the
configure script. Search for "Fortran could not compile .f90 files" and you
will see the error messages that the ifort compiler is giving. (You can also
just try to compile from the command line. Does it work?)

Basically the netCDF configure program is telling you that your fortran
compiler is not working. Until it is, the netCDF fortran APIs and tests won't
be built.

Please let me know if you can't get this working.

Thanks,

Ed

PS - You may wish to upgrade to the 4.0.1 release, but it will not affect your
current fortran problem.
