Is "-lnetcdf" in the correct place in your link command? Maybe it should be at
the end?

Are you using the same fortran compiler that you used with the netCDF build?

Can you use the nm command to see if these functions are really in your
library?

The Unidata support team is mostly just me. ;-)

--enable-64bit was an option in 3.6.1 but I took it out for 3.6.2, because it
was too hard to maintain and too weird.

However, I neglected to take it out of the documentation. I've fixed that now,
so that the snapshot documentation, and the docs for the next versions, will be
correct. Sorry about the confusion.

If "make check" in the nf_test directory successfully runs the netCDF fortran
tests, then your netCDF fortran library is working, so your problems are in
your linking to it from your model build.

Thanks,

Ed
