For configuration and compilation it is necessary to have the
PGPLOT plotting library installed. PGPLOT is a standard tool in astronomy,
that is available for a large range of UNIX systems, as well as for Linux, and
is free for non-commercial usage.
If it is not installed on your system, it can be downloaded from
http://astro.caltech.edu/~tjp/pgplot/
(ask your system administrator for assistance). Some Linux distributions
(e.g. Debian) have precompiled binary packages.
- PGPLOT is a Fortran library, while Cora is a C program. Therefore
the C wrapper library cpgplot that comes with PGPLOT must
be installed as well (compiled with make cpg).
- PGPLOT uses a font file (grfont.dat), whose location must be known
at runtime.
For this purpose, PGPLOT uses an environment variable PGPLOT_DIR,
that points to the directory where the font file is installed.
Failure to set this environment variable will at least result in crappy
plots, if not worse.
- If ./configure fails to find your installed PGPLOT library files,
you can use the following options:
- -with-pgplot-include=DIR
- -with-pgplot-lib=DIR
to make the location of the include file (cpgplot.h) and
the library files (cpgplot.a and pgplot.a, or cpgplot.so and pgplot.so)
known to ./configure.
