Hi Tan,

Glad you were successful. Were you also able to get your code to compile?

I think you simply need to add -L/usr/local/lib to your
ncargf77/ncargcc/ncargf90/etc compile line.

You can also edit the $NCARG_ROOT/bin/{ncargf77,ncargf90,ncargcc/etc} file
directly (using a UNIX editor) and add "-L/usr/local/lib" to the "set
syslibdir" line.

The cairo library has dependencies on pixman-1, fontconfig, freetype, and
possibly expat. You may need to install these libraries in a similar
fashion as you did for cairo, if you continue to get undefined references.

ubuntu's Linux package installer is unable to find libcairo-devel to
install. I instead installed cairo version 1.10.2 manually following the
instructions given at:

Preprocessing System (WPS), the following error occurs. There is a large
number of them so only a few are listed in the mail. I have also attached
the entire compile log which contains all of the errors.
