10   SWI-Prolog

10.1   What is SWI-Prolog

If you want to use Prolog you need a compiler. There are many compiler downloadables on internet. For this report we used SWI-Prolog. SWI-Prolog is free Prolog compiler licenced under the GPL, targeting primaly the research and education.

10.2   Author

SWI-Prolog is designed and implemented by Jan Wielemaker from the University of Amsterdam, department of Social Science Informatics (SWI).

10.3   Platforms

SWI-Prolog is written in ANSI C and should configure for most Unix machines having an ANSI C Compiler.
Ports have been made for :
  1. MS Win32
  2. MS Win3.1
  3. MS DOS
  4. OS/2

10.4   FTP Sites

The main ftp-site to download SWI-Prolog is :
ftp://swi.psy.uva.nl/pub/SWI-Prolog/

Latest version of the sources :
ftp://swi.psy.uva.nl/pub/SWI-Prolog/pl.tar.gz

Latest binary for use with with Win32 :
ftp://swi.psy.uva.nl/pub/SWI-Prolog/w32pl.exe
