This is a function that is defined by the version of openGL we use.
There are some subtleties that I don't quite understand: 1) There are graphics drivers that screw with OpenGL. Some of these are laptop-specific (e.g., the laptop cannot use the drivers on the graphics card manufacturer's Web site). Some are Microsoft issues (e.g., distributing drivers that do not work quite right for anything but DirectX). I'm not aware of a missing glLoadTraposeMatrixf being caused by these, but that doesn't mean much. 2) There's a Windows memory management issue in which large footprint programs (including Squeak) seem to cause the opengl library to not load up the stuff it needs. Andreas created a new Windows VM that tries to avoid this, and which is included in Versions 7 and 8 of the Croquet Collaborative distribution and also at squeakvm.org. Interestingly, all the failure examples I can find seem to involve Dell machines. (Andreas' VM definitely fixed my office Dell laptop's problem.) Regardless of the cause, Oliver Bye posted ("Error rendering world") a workaround that uses matrixes in a different form, using an additional operation. !OpenGL methodsFor: 'GL_ARB_transpose_matrix' stamp: 'oib 9/24/2006 09:20'! glLoadTransposeMatrixf: m "Hack to support Dell Latitude D610 Intel Graphics" ^self glLoadMatrixf: m transposed.! ! !OpenGL methodsFor: 'GL_ARB_transpose_matrix' stamp: 'oib 9/24/2006 09:22'! glMultTransposeMatrixf: m "Hack to support Dell Latitude D610 Intel graphics" ^self glMultMatrixf: m transposed.! !

Aargh, that transpose matrix problem again. This has cropped up for a
few times. Wasn't this fix included? https://lists.wisc.edu/read/messages?id=896920 Additionally, the discussion here resulted in a method that tries the OpenGL version first before doing the transpose manually (which is slow): https://lists.wisc.edu/read/messages?id=1115329 - Bert - On Mar 10, 2007, at 4:10 , Howard Stearns wrote: > This is a function that is defined by the version of openGL we use. > There are some subtleties that I don't quite understand: > > 1) There are graphics drivers that screw with OpenGL.

It looks like neither your original fix was included, nor the dynamic-
define-a-slower-method-on-fall-through fix you discussed with Enrico. I've created a ticket (http://bugs.impara.de/squeak/view.php?id=6338). Andreas owns the package (OpenGL-Core), but he's completely swamped right now. I'm going to go out on limb, though, and suggest that if someone offers a tested new version of this package, we can find a way to get into the repository. I can offer some naive testing by using the pre-1.0.5 Windows VM on a box that wasn't handling ARB before.
