<TITLE>Downloading and Installing Lisp Code for AIMA</TITLE>
<!-- Changed by: Peter Norvig, 24-Jul-1996 -->
<BODY bgcolor=#ffffff>
<H1>Downloading and Installing Lisp Code for AIMA</H1>
This page gives instructions for retrieving the code for the book, and
installing it on your local system. This installation procedure need
only be followed once. If you are using the book in a course, your
instructor (or an assistant) will probably do this for you, and you
can move on to <A HREF="user.html">using the code</A>.
<H2>Downloading the Code</H1>
The Lisp source code (and documentation) that accompanies the book is packaged
up in the file <A HREF="ftp://ftp.cs.berkeley.edu/ucb/people/russell/aima/code.tar.Z">code.tar.Z</A> in the directory <A
HREF="ftp://ftp.cs.berkeley.edu/ucb/people/russell/aima">/ucb/people/russell/aima</A> on the machine ftp.cs.berkeley.edu. To download the code, you have four choices:
<OL>
<LI> Select <A HREF="ftp://ftp.cs.berkeley.edu/ucb/people/russell/aima/code.tar.Z">code.tar.Z</A> from your Web browser.
<LI> Use ftp directly. On a UNIX
system, a typical ftp session looks like this: <P>
<PRE>
Computer prompts: You type:
================ ========
% cd <I>where-you-want-the-code-to-be</I>
% ftp ftp.cs.berkeley.edu
Name: anonymous
Password: <I>your-login-name@your.mail.address</I>
ftp> cd ucb/people/russell/aima
250 CWD command successful.
ftp> binary
200 Type set to I.
ftp> get code.tar.Z
150 Opening ASCII connection
226 Transfer complete.
ftp> quit
221 Goodbye.
% zcat code.tar.Z | tar xvf -
% rm code.tar.Z
</PRE>
<LI> If you don't have the zcat (or uncompress) and tar programs, or another
suitable unpacking utility, you can get the files one at a time from the ftp site, or by using a web browser to the <A HREF="code/">code directory</A>.
<LI>If you don't have access to ftp, but do have an email account, you can
retrieve the files by sending a message to <A HREF="mailto:ftpmail@decwrl.dec.com">ftpmail@decwrl.dec.com</A> with
the following body (or send a message with the body <I>help</I> to see all
your options):
<PRE>
connect ftp.cs.berkeley.edu
binary
uuencode
get README
get code.tar.Z
quit
</PRE>
</OL>
<H2>Installing the Code</H1>
<OL>
<LI> Make sure you have both read-permission and write-permission for
the directory where the code is kept.
<P><LI> Edit the file "aima.lisp" and change the value of the parameter
*aima-root* to reflect the location of the files. Make sure to use the
proper syntax for a directory, not a regular file. For example, on a Unix
file system, you want something like "/usr/local/aima/", where the final "/"
indicates that /usr/local/aima is a directory.
<P><LI> Depending on your version of Lisp, you may need to edit the parameter
*aima-binary-type* to indicate the type of files created by your Lisp
compiler. If the compiler creates files of the form "name.bin", then set
this parameter to "bin". Do include the double-quote marks.
<P><LI>Start up your Common Lisp, and enter the following two forms:
<PRE>
(load "aima.lisp")
(aima-compile)
</PRE>
<P><LI> Most versions of Lisp provide a way to dump out an image -- an
executable file that contains all the code that has been loaded so far. If
your Lisp has this feature, it might be a good idea to create such an image
at this point, and save it for later use.
<P>Then exit from Lisp (and if you like, you can remove write-permission from
this directory and its sub-directories).
</OL>
