Try inspecting the following to confirm the module is present:

SmalltalkImage current listLoadedModules

if not then same on:

SmalltalkImage current listBuiltinModules

Hi,

I'd like to experiment with OpenGL in Squeak. I found the promisingly titled "Howto - Loading OpenGL in Squeak 3.9" from Jakub Kozisek (http://lists.squeakfoundation.org/pipermail/beginners/2006-November/001451.h...) and followed the directions:

• install FFI and Balloon3D from SqueakMap. (I used the Universe browser to

install FFI version 3.9.1 and Balloon3D version 0.18.2)

• install OpenGL-ckl.4.mcz from Monticello repository at

http://www.squeaksource.com/OpenGL

• apply change set from

http://lists.squeakfoundation.org/pipermail/beginners/attachments/20061118/4...

• ensure squeak.ini contains: B3DXUsesOpenGL = 1
• OpenGLMorph new openInWorld.

Unfortunately the instructions resulted in the following error:

...

...

...

Error: Error a primitive has failed

Examining the stack trace the error was in:

B3DPrimitiveRasterizerState>>primInitializeBuffers

which reads: B3DPrimitiveRasterizerState>>primInitializeBuffers <primitive: 'b3dInitializeRasterizerState' module:'Squeak3D'> ^self primitiveFailed

I ran the shipped FFI tests and all tests passed. I'm running under windows using a VM from SqueakVM-Win32-3.10.6-bin.zip and an image sq3.9.1-7075dev08.07.1

I downloaded Croquet which displayed it's 3D world successfully, but would prefer a minimal OpenGL installation. I tried the Croquet VM with my image, but got the same problem.

Any ideas?

Nick

lol, dug up a Croquet install and it is nearly a year since I used it :-) Probably better if someone else chipped in with advice. Only thing I can think is that opengl32.dll cannot be found. Here it is in c:\windows\system32 but if you want to be sure then drop a copy in the squeak directory. Works here in CroquetCollaborative-1.0.

Hi Derek,

thanks for the reply. I've inspected "SmalltalkImage current listLoadedModules" and "SmalltalkImage current listBuiltinModules" and there is no sign of "module:'Squeak3D'". I also checked my Croquet installation and again no sign of "module:'Squeak3D'" - however the Croquet image appears to have a different installation of OpenGL; there is no sign of Balloon3D*.

Do I need a "Squeak3D.dll" module is so where would I find it? Google points me to http://wiki.squeak.org/squeak/2874, which is interesting but that particularly helpful.

Are there two separate implementations of OpenGL in Squeak - one in Croquet and one in "standard" squeak.

confused
