It appears that the NAG f95 environment on your system doesn't support
getopt(3f), which is the standard way of obtaining command-line
arguments in a Unix environment.  It could be that you need to add a
particular library reference to the command that builds the test program
"fortran/nf_test".  I don't know what that referece might be (check
with your documentation).  If you can't find any support for getopt(3f),
then I would complain to the vendor of the development environment for
not supplying a complete environment.

We have no experience building the Fortran interface of the netCDF package
using the Lahey Fortran compiler.  It could be that it uses the same
Fortran-calling-C conventions as NAG Fortran -- but if experience is
anything to go by, then it probably doesn't.

You might try posting to the netcdf mailing-list.  Perhaps someone on it
has successfully built the netCDF package using the Lahey Fortran
compiler.

The file "fortran/nfconfig.inc" should have been created by the configure
script when it was executed.  That it wasn't indicates a severe problem.

You should be able to (re)create it by executing the command
"./config.status" in the top-level source directory.  Failing that, then
your best bet is to start over from scratch:

    1.  Go to the top-level source directory.

    2.  Performs steps 3 through 9 near the end of the INSTALL file.
