With C application code compiled using pgcc, it should be OK to call a
netCDF library built with gcc.  Is the user code a Fortran application
that is calling the Fortran netCDF API?

In that case, it's likely that you will need a netCDF library built
for the PGI convention for how Fortran code calls functions in a C
library, because there was no standard way to do this before
Fortran-2003, and we don't yet support the Fortran-2003 standard.

The Portland Group maintains instructions for how to build netCDF with
their compilers:

and recommends using pgcc with pgfortran, but our testing was
successful with netCDF version 4.1.1 using gcc with pgf95 in our on a
32-bit Linux system:
