[ncl-install] Compiling cpex08 on a Sun Solaris 10 system

[Mary Haley]

Craig,

First the "ncarg77" was a typo on my part. It should have been "which
ncargf77".

I'm not sure why "ncargex cpex08" is not working on your Sun, because
it works just fine on mine.  There may be an issue if you are using a
significantly older or newer version of the compiler.

Anyway, you need to include some additional libraries.  Try "-lfsu" at
first:

   f90 -O -o cpex08 cpexcc.f cpex08.f -L/wrf/test/lib
    -L/usr/openwin/lib -lncarg -lncarg_gks -lncarg_c -lX11 -lXext -lfsu

This may cause more undefined's. If so try:

   f90 -O -o cpex08 cpexcc.f cpex08.f -L/wrf/test/lib
    -L/usr/openwin/lib -lncarg -lncarg_gks -lncarg_c -lX11 -lXext
    -lf77compat -lfsu -lsunmath -lfui -lm

I would hope that you don't need all of these. It may be necessary,
however, unless you want to try rebuilding NCAR Graphics from source
code so you can use your version of the compiler.
