The above message contained the following:

I'm afraid that I don't use the system you describe, so I don't know if
the above is correct.

Did you try calling nc_strerror with the error return codes listed in
the header-file "netcdf.h"?

-33 means "Not a netcdf id".  I don't know what 22 means (indeed, I
don't think you should get a 22).

> What am doing wrong?

I don't know.  We test the netCDF package fairly comprehensively, so I'd
be surprised if there was something wrong with it at the level of your
problem.

Since we can't help you because we don't have your system here, you
might try posting an inquiry to the netCDF mailing-list.
