LispForum

Hi all,
I am trying to compile / run the following code by Professor David W. Jacobs of the University of Maryland. The URL for the code is:
http://www.cs.umd.edu/~djacobs/convex-grouping.tar

I am new to Lisp and have hit a brick wall trying to achieve my goal. If possible could someone please try to run this code and if successful provide a list of steps for me.
I am working in a Ubuntu environment.
Many thanks,
Padraig

You are not doing anything wrong. The original author used an ad-hoc system to load his code. It was brittle. Also, there were a bunch of issues leftover from the early days of CL (some pre-standard notations).

I cleaned it up to make this tarball.
http://libcl.com/tmp/convex-groups.tar

Don't load the documented "system" files. Instead, load "load-all.lisp". Not as fancy, but it works.

Note that the author disabled most of the graphic output routines. Note also that I didn't test proper functionality since I don't have "raw edge files".
