[netCDF #UAT-411621]: getting undefined reference when compiling netCDF4.2 Fortran

Hi Steve,

Rather than using compiler flags related to underscores, I recommend
following the steps here, which work with many compiler combinations
without messing with underscores in function names:

  http://www.unidata.ucar.edu/netcdf/docs/netcdf-fortran-install.html

The instructions above explain when LD_LIBRARY_PATH may be required in
addition to LD_FLAGS and CPPFLAGS settings.  If this doesn't work for
you, we might be able to provide more help if you send the config.log
file generated by the configure script when you start building the
netCDF Fortran API from source.

Also, it would be better to use the most recent netCDF C release, version
4.3.1.1, with netCDF Fortran 4.2.  It has various bug fixes and
other improvements since netCDF C 4.2 was released, and it's compatible
with netCDF-Fortran version 4.2.
