I guess I should have asked earlier if you have installed netCDF-4, without
using the --disable-netcdf-4 option. To install netCDF-4 you would have
had to install hdf5 first, because netCDF-4 depends on it. To determine
whether you have netCDF-4 installed, try running ncdump on the attached binary
file:
ncdump -k test.nc
and verify that the output is
netCDF-4 classic model
If instead you get
test.nc4: NetCDF: Unknown file format
then you haven't installed netCDF-4, which is required for the netcdf-cxx4
software that depends on the C library for netCDF-4.
