Howdy Rich!

Looks to me like you are not linking to the HDF5 libraries. You must change
your build like to something like this:

     cc -o myprogram myprogram.o -L/usr/local/netcdf/lib -L/usr/local/hdf5/lib
     -lnetcdf -lhdf5_hl -lhdf5 -lz

That is, where you currently have "-lnetcdf", you need "-lnetcdf -lhdf5_hl
-lhdf5 -lz"

Please let me know if this doesn't work for you. I would also be very
interested to hear about your netCDF-4 experiences with WRF.

Thanks,

Ed
