John,

Are you using the netcdf-3.5.0.tar.Z file from the pub/binary/linux_2.2-i686
of our anonymous FTP site, ftp.unidata.ucar.edu?  If so, I just verified
that the entry points you list below are in the library, libnetcdf.a.

>I keep getting the following errors found below (and more u.  Any ideas.

The errors you list appear to be from a link step.  If you are using the
binary netCDF 3.0.5 distribution for Linux that I refer to above, then
the problem is most likely that you are not telling the linker where
to find the netCDF library.  Beyond that, we don't have enough information
about what you are trying to do to be really sure where your problem lies.

You can verify the existence of entry points in a library by using
the 'nm' utility on Linux:

% nm libnetcdf.a | grep nf_inq_var_
% nm libnetcdf.a | grep nf_get_att_int_

etc.
