Hi Sam,
I think this is just because "ncargex" is using "ncargf90" as its
default script to use for compiling a program. There should be an
"ncargf77" script you can use, that invokes f77 instead. See below.

I think you might just be missing a system library here. Perhaps you
need to load an additional Absoft library? I don't remember what
version of Absoft NCAR Graphics was built with, but chances are you
have a newer version. This sometimes this causes a slight
incompatibility, which you may be seeing here. I think if you pull in
the necessary system libraries, you might be okay.

"ncargex" doesn't access a Makefile. It calls "ncargf90" (or
"ncargf77") which is just a C-shell script for compiling NCAR Graphics
programs.

Take a look at $NCARG_ROOT/bin/ncargf90 and/or
$NCARG_ROOT/bin/ncargf77. One of these scripts are the ones being
used to compile your program. You can edit them and add/remove
compiler options, libraries, etc as necessary.

Please see the above about system libraries.

I believe once you get the ncargf77 and/or ncargf90 scripts tuned for
your system, then users will be able to use these scripts to compile
their NCAR Graphics programs. For example:
ncargf77 cpex08.f cpexcc.f -o cpex08

Hope this helps you get started.
