[netCDF #XRT-704709]: Compilation errors

Akaïwoung,

I'm sorry to hear that.  Another possible problem that has the same symptom
is that the library you got using apt-get either did not include the Fortran
interface (for example, it could have been built with the --disable-fortran
configure option), or it was built with a different Fortran compiler than the 
gfortran you have installed on your system.

You could get around these errors by just building the library from source and
installing that on your system.  It's pretty easy to build from source, 
especially if you don't need the DAP remote client or the HDF5 support
required for the netCDF-4 data model.  It sounds like you don't need those
capabilities for converting NCEP/NCAR netcdf data to binary data.

In that case, you could just follow the "Quick Instructions for Installing 
NetCDF 
on Unix" that are here:
