Hi,

First, I hope you are the person for which this reply is intended.  We
just got a question about netCDF software from

  A/Prof. David Edelman, Univ. of Wollongong

but the return email address on the message, "davide@dedalus (David
Edelman)", was incomplete, so I came up with your email address after a
search.  If you are not the David Edelman to whom this should be
directed but know his email address, could you kindly forward this note
to him?  Thanks.

The XDR library on SPARC/Solaris systems is available in the
/usr/lib/libnsl library, so you need to add "-lnsl" to your link lines.
This is one of the systems referred to in the documentation on page 35
that says:

    On some systems, you must specify an additional library after the
    netCDF library where the system XDR libraries are found.

One way to find what flags are used in compiling and running netCDF
Fortran programs on your platform is to change to the netcdf
src/fortran/ directory, remove the test program "ftest", and remake it
by invoking "make test", which should result in something like:

    f77 -o ftest ftest.o -L../libsrc -lnetcdf -lnsl
    ...

but may differ, depending on what Fortran compiler you are using.  The
"-L../libsrc" should be replaced by something that indicates where your
netCDF library is actually installed, and you should include whatever
flags follow "-lnetcdf".  The User's Guide does not include this hint,
because the netcdf src/ directories are not always available to users.

I hope this helps.
