Requirements

- The version 3.1 of the command interpreter library interpcom. It can be found at

ftp://ftp.ibiblio.org/pub/Linux/system/shells

or

http://www.math.jussieu.fr/~drezet

- The cephes library of functions, that can be found at

ftp://ftp.ibiblio.org/pub/Linux/lang/c

Only the library of double precision routines (libmd.a) is used in funct.

- The gsl library (for the FFT routines) that can be found at

ftp://ftp.gnu.org/gnu/

The graphic part of funct can be built in 4 different ways :

- The simplest and prefered ones are to use GNU plotutils, that can be found at

ftp://ftp.gnu.org/gnu/

and provides X11, PNG, GIF, Postscript and FIG graphics, or g2, that can be found at

http://g2.sourceforge.net

and provides X11, PNG and Postscript graphics. The g2 library uses the gd library that can be found at

ftp://ftp.boutell.com/pub/boutell/gd/

In the two other ways the PNG and Postscript graphics are done with g2. For X11 graphics there are two choices :

- The allegro or ggi libraries. Allegro can be found at

http://alleg.sourceforge.net/

and ggi at

http://www.ggi-project.org/

The version of funct using g2 and allegro has been ported to BeOS.
