[ncl-install] problem running graphics

[Mary Haley]

Ben,

You don't appear to have the X11 libraries installed on your system.  
Either that, or they are
not installed to /usr/X11R6/lib.

I *think* you can compile without X11, but then you will not be able  
to send your output
to an X11 window.  Try:

ncargex -noX11 cpex08

For the longer term, I recommend getting the X11 libraries installed  
on your system.

If you do have the X11 libraries (libX11.a, libXext.a, etc) already on  
your system,
then use the "-L" option to point to this location, and compile the  
program with:

gfortran -fPIC -fno-second-underscore -fno-range-check -O -o cpex08
cpexcc.f cpex08.f -L/usr/local/lib -L/path/to/X11/libs -lncarg - 
lncarg_gks -lncarg_c -lX11 -lXext -lpng -lz

where "/path/to/X11/libs" should be replaced by the path to your X11  
libraries.
