The netcdf.inc file is installed as part of the process of building and
installing the netCDF library from the source distribution available from
Unidata's FTP site.  As part of the installation process, you choose where
the netcdf.inc file and the library get installed.  /usr/local/ is one
possible installation location, but you can choose a different root for
installing these files.  

netcdf.inc is just a file that contains Fortran PARAMETER declarations and
type declarations that make it easier to use the netCDF library from
Fortran.  For example, the constant "NCCLOB" in the statement

       ncid = NCCRE('test.nc', NCCLOB, errcode)

(from the example program that I sent) is a Fortran parameter defined in the
netcdf.inc file, so you don't have to know its value to use it with the
NCCRE() call to create a new netCDF file.

> Also, could you outline the steps necessary to create the NetCDF library?

The process of installing the netCDF library is described in detail in the
netcdf/INSTALL file that comes with the source distribution.  If you
encounter a problem following the steps described in that document, please
send a specific question about the problem to address@hidden.
