Ruby-opengl glut on osx

ruby-talk
1

I grabbed the port of ruby-opengl for OSX from
http://www.lazyatom.com/software/opengl-0.32f.tar.gz and installed it.
When I try to run any program (or even require 'opengl', I get the
following error, which kills ruby:

objc: failed objc_getClass(NSObject) for GLUTApplication->isa->isa
objc: please link appropriate classes in your program

Trace/BPT trap

I don't know much about OSX programming, so I have no idea what this
means. When the library links, it does link against the OpenGL and
GLUT frameworks, so I would think it would know where to find the glut
and OpenGL stuff, but maybe it doesn't. Any help would be much
appreciated.

I have an updated version of my patched OpenGL module - I'll post
details in a reply to this thread in the next few days.

I would be interested.

I was able to get opengl and glut to work on tiger, but only when the
file is in the install folder opengl-0.32g
http://groups.google.com/group/comp.lang.ruby/browse_frm/thread/63a62226ede67ed7/084df49e33769742?q=opengl+anne001&rnum=2#084df49e33769742

so I am interested if there is another way of installing opengl, so I
can have my files anywhere on my computer.

I've uploaded my updated version of the OpenGL extensions to the following URL:

http://www.lazyatom.com/software/opengl-0.32g.tar.gz

You should have the Developer Tools and the GLUT framework sources
(available from Apple) installed for this. It builds and links against
the Apple-native OpenGL/GLUT libraries, so no X11 is involved.
