Are you running this on clozure 1.5 with Snow Leopard MAC OS (ie: version 10.6.4 ) ? On Aug 5, 2010 4:36am, Alexander Repenning <ralex@cs.colorado.edu> wrote:

XMLisp http://code.google.com/p/xmlisp/ works fine, ie, it is not an OpenGL problem.

further to this message.. I tried the lastest svn "trunk" release of ccl (which incidentally looks like it has some extra goodies in it for the mac platform).. Here is what I get (after startup)..

Welcome to Clozure Common Lisp Version 1.5-dev-r13523M-trunk (DarwinX8664)! ? (require :cl-opengl) Trace/BPT trap

All other require packages got loaded successfully on startup prior. I played around with "trace" and "step" but none of those debugging functions seem to give me the equivalent of a "stack trace' in C. Not sure how to proceed to find out where it is crashing...

Thanks, Kevin

The only hurdle for me for trying out (and maybe switching) to clozure on the mac platform is that I can't seem to get the cl-opengl package loaded. I get the error: "Trace/BPT trap" when I try to load that package. (All other dependent packages like cffi, loaded successfully).

I am using ccl64, version 1.5 on Darwin/MAC OS (DarwinX8664). Latest version of cl-opengl.

I believe I also tried it on the 32-bit ccl. Same problem. It looks like it only compiles a few source files in the cl-opengl package before it dies.

If someone can point out to me how I can trace this to provide more information on where it is crashing or maybe someone has run across this already with this particular package.

Thanks, Kevin
