Hello all,
I'm having issues getting cl-opengl working on Snow Leopard 10.6.2. I
definitely had some working Lisp OpenGL stuff on my previous laptop
(plain old Leopard) but the switch to SL seems to have caused a show
stopper (maybe something to do with 64 bits?).
I'm using SBCL 1.0.35.2, compiled myself from git. I haven't enabled
threads because they are a bit shaky on Mac, and I've specifically
compiled a 32 bit version because I have some 32 bit libraries I'd
like to link to.
I'm using the latest version of cl-opengl from darcs. I open up a new
lisp, load :cl-glut-examples using ASDF, and then move into the
package and try to run a demo (for the sake of argument #'RB-HELLO
although this appears to happen with everything) and the lisp dies
with this fairly cryptic error message:
* (in-package :cl-glut-examples)
#<PACKAGE "CL-GLUT-EXAMPLES">
* (rb-hello)

The only clue I have is that when loading the fasl files (I've deleted
and recompiled all these a bunch of times so I'm pretty sure there's
nothing stale in here) I get the warning you can see at the bottom of
this snippet - the style warning may be nothing but the GLUT warning
looks ominous.

Does anyone have any ideas on how to track this down? I'm digging
through the code right now but I'm by no means skilled at opengl or
lisp so it's hard going..
Many thanks,
Malcolm
