The flag -L points to libraries which are staticaly linked
to your
application. Those libraries are usually named *.a.
Dynamically linked
libraries (*.so) are linked with your application at runtime
and can be
pointed to by the environment variable LD_LIBRARY_PATH.

If you have a file libnetcdf.a and that file contains the
function
nf_close_ it might help to put that .a file in a directory
pointed to with
the switch -L.

Probably not.  The error here is about a missing function,
not a
missing library.  ld is finding all the libraries it was
told to
include, but none of those libraries have this function.

Greg, your best bet is to get help from whoever wrote the
program
you're trying to build.

It's probably better to add a new -L switch, with the path
to the library,
rather than moving it.

nm (name) will list all the symbols in a library.
Use --defined-only to see which symbols it provides, rather
than the symbols it requires.
