XTAG was developed on the Sun SPARC station series. It has been tested
on various Sun platforms including Ultra-1, Ultra-Enterprise. XTAG is
freely available from the XTAG web page at http://www.cis.upenn.edu/~xtag/. It requires 75 MB of disk space
(once all binaries and databases are created after the install). XTAG
requires the following software to run:
- A machine running UNIX and X11R4 (or higher). Previous releases
of X will not work. X11R4 is free software which usually comes
bundled with your OS. It is also freely available for various
platforms at http://www.xfree86.org/
- A Common Lisp compiler which supports the latest definition of
Common Lisp (Steele's Common Lisp, second edition). XTAG has been
tested on Lucid Common Lisp/SPARC Solaris, Version: 4.2.1. Allegro
CL is no longer directly supported, however there have been third
party ports to recent versions of Allegro CL.
- CLX version 4 or higher. CLX is the Lisp equivalent to the Xlib
package written in C.
- Mark Kantrowitz's Lisp Utilities from CMU: logical-pathnames and
defsystem.
A patched version of CLX (Version 5.02) for SunOS 5.5.1 and the CMU
Lisp Utilities are provided in our ftp directory for your convenience.
However, we ask that you refer to the appropriate sources for updates.
The morphology database component ([#!karp92!#]), no longer under
licensing restrictions, is available as a separate download from the
XTAG web page (see above for URL).
The syntactic database component is also available as part of the XTAG
system ([#!EgediMartin94!#]).
More information can be obtained on the XTAG web page at
