[netCDF #HBB-707489]: Error When Building NetCDF4.3.1

Hi,

> I am trying to link to the libraries to run the code.  What module do I link 
> to? My code is in FORTRAN, and the following is what I use for compilation:
> 
> gfortran -o nc nc.f95 -L/Users/Stefan/cool/lib -I/Users/Stefan/local/include 
> -I/Users/Stefan/cool/include -lhdf5 -lhdf5_hl -lz -lnetcdf

It depends on whether you built shared libraries (the default) or static 
libraries
(with the --disable-shared option to the configure script), as explained here,
under the section "Linking your programs with netCDF Fortran libraries":

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

In either case, you need to use -lnetcdff, but with static libraries, you will 
also need -lnetcdf.

You should still be able to use "use netcdf".  The "netcdf.inc" file is for the 
old Fortran-77 API, which is still supported in the netCDF Fortran library.

Yes, but it's less confusing if you use shared libraries, in which case the
linking is straightforward.

You can also use the command "nf-config" to provide necessary directories
and flags, as in:

  gfortran -o test test.f90 `nf-config --fflags --flibs`

or pkgconfig, if your platform supports it, as in

  export PKG_CONFIG_PATH=/opt/lib/pkgconfig  # or whatever
  gfortran test.f90 -o test `pkg-config --cflags --libs netcdf-fortran`

This latter is not tested as well, but it may be working ...
