You are writing fortran code? With the absoft compiler?

In that case you shouldn't have to do anything special to get at the
fortran function calls. The program src/nf_test/nf_test.f does exactly
that. Try looking at the compile command for that (from doing make
test, or, on an already built-up codebase, go to the nf_test directory
and do "make clean test").

You're compile command certainly has to include the directory where
you installed the netcdf library. Perhaps that's the problem.

Start with nf_test.f and insert some of your fortran code that calls
netcdf. If it works there (and it should, since the tests pass), then
you can figure out the difference between it's compilation and your
own codes'.

When building the fortran library (from C code) the C preprocessor
flag -DabsoftFortran is needed, but nothing like that is needed when
linking to the fortran code in the library.

Incidentally, if you take a look at my message, and the other-builds web
page, you'll see that I built with absoft fortran without any patches,
and without any FCFLAGS, and everything worked. Do you know the
meaning of the compiler flags you are using? I don't, since I don't
work with absoft.

Let me know if this helps. 

Thanks!

Ed
