Tony,

If you are compiling an NCAR Graphics C or Fortran program, you are calling NCAR Graphics routines that in turn are calling cairo routines, so you must link to cairo libraries in order for the program to compile successfully.  We don't provide cairo as part of the NCL/NCAR Graphics binary installation because this is a separate package.

If you are just using NCL, then yes, the cairo and other libraries are built into the "ncl" executable, so it's not necessary to install cairo and everything else.

We recommend that people use NCL over NCAR Graphics, if possible.  NCL is a full scripting language that provides you with file I/O, computational routines, and graphics.  NCAR Graphics only provides you with graphics, and you have to write quite a bit more code in order to get a graphic out of it.

If you are interested in finding out how and if you can switch from NCAR Graphics to NCL, let me know.  I can take a look at the type of graphics you're creating with NCAR Graphics and let you know what it would take to do this in NCL.
