[ncl-install] NCAR Graphics test doesn't work

[Mary Haley]

Hi Kevin,

To answer your first question, the binary is relocatable. You can put it
wherever you want. You just need to be sure to setenv NCARG_ROOT to point
to the parent location, and add $NCARG_ROOT/bin to your search path, which
it sounds like you did.

For the "ncargex cpex08" issue: If you only plan to use NCL, then it's not
important that this test work. The "ncargex" command tests the C and
Fortran libraries for people that are using C and/or Fortran to generate
their graphics, rather than NCL.

If you still want to get this test to work, then I think the issue is that
you have a libXext.so.x.y file, but not a libXext.so file.  Usually
libXext.so is a symbolic link to libXext.so.x.y. You might want to look
into how this software was installed, and make sure it was installed
correctly.
