Croquet on Debian Testing: problem with OpenGL

Hi,

I've problems with running Croquet SDK on my
up-to-date debian testing box. After opening
any world, an error is raised:
Error: Cannot initialize OpenGL

After some debugging, I noted that problem
is in OGLUnixX11LE>>initializeIn:
because (primitive) method
OGLUnixX11LE>>primCreateRenderer: flags x: x y: y w: w h: h
returns nil.

I also notices, that every time the
OGLUnixX11LE>>primCreateRenderer: flags x: x y: y w: w h: h
is invoked
--
X error
X error
X error
X error
--
is printed to standard output.
I tryed to read B3DAcceleratorPlugin .c sources,
but I was unable to find function
primitiveCreateRendererFlags() sources.

Has anybody same problem?
Has anybody any idea what could be wrong
and/or what to check? Any other suggestions?

Thanks.

Have a look at sqUnixOpenGL.c which handles that part:

http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/unix/plugins/B3DAcceleratorPlugin/sqUnixOpenGL.c?rev=967&view=auto

It looks as if most of this is actually handled in the display backend
which can be found here:

http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/unix/vm-display-X11/

Cheers,

Hi,

yes, I did. GLX and DRI stuff works fine with
other appc. glxinfo says:
--
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
--
(full output is attached)

Also, all the libraries are on place (I think):

Set your display depth to 32.

Croquet needs an accelerated visual with stencil buffer, which,  
according to your glxinfo output, is not available.

Hmm...I've tryed to set 32 bit depth but the
radeon driver said that 32 bit depth is not supported.
Maximum is 24, and Croquet doesn't run on 24bpp too.

Does this means, that my system
(IBM T41 with ATI Mobility Radeon 7500)
is unable to run Croquet?

Previous Croquet version runs fine.

Thanks. Jan
