Frank, IIRC there's a null-character stuck in the source code of that method. I brought this to Nikolay's attention last March but it may not have gotten fixed. If you delete that character,at least you'll at least be able to step through that method...

Hello,

Let me introduce the Curved Space Explorer for Squeak project (https://vimeo.com/71173349), known as CCSE by Krestianstvo SDK. It is a Smalltalk port version of Curved Spaces, originally developed by Jeff Weeks (geometrygames.org) in C language. This Squeak version is derived from Krestianstvo SDK project's version, where Curved Space Explorer is collaborative in it's nature and available mainly for distributed computation. The aim of this project is to make Curved Space Explorer in Smalltalk being available for the large Smalltalk audience and mainstream Squeak distribution, so that anybody interested could work with it. The source code is available here: http://sdk.krestianstvo.org/sdk/ccse.html Preinstalled Squeak image is here: http://krestianstvo.org/sdk/Squeak4.4-12327-ccse.zip For manual install use following instructions: (is tested and working with Squeak 4.4 and Squeak 4.5 alpha)

"1. Load FFI"

(Installer repository: 'http://source.squeak.org/FFI') install: 'FFI-Pools'; install: 'FFI-Kernel'; install: 'FFI-Tests'.

"2. Load 3DTransform "

(Installer repository: 'http://www.squeaksource.com/CroquetGL') install: '3DTransform'.

"3. Load OpentGL and CCSE"

(Installer repository: 'http://sdk.krestianstvo.org/sdk/ccse') install: 'OpenGL-Pools'; install: 'OpenGL-Core'; install: 'OpenGL-NameManager'; install: 'CCSpaceExplorer'.

"4. Run sample application"

CCSEMorphRender runApp

Cool! Thanks!

I just tried it on my work machine (Ubuntu 13) and ran into an odd problem. I'm getting told "MessageNotUnderstood: BlockContext>>". Note that it is indeed complaining that BlockContext doesn't understand #'' !

The error appears immediately after this runs:

OGLUnixX11LE >> openGLLibraryName ^Smalltalk osVersion = 'linux' ifTrue: ['libGL.so.1'] ifFalse: ['GL']

Now on my machine Smalltalk osVersion = 'linux-gnu', but I get the weird error even when I change the conditional to `Smalltalk osVersion beginsWith: 'linux'`. I find it utterly bizarre that something should try to send #'' to anything after this call. Clearly something's gone wrong, and it's almost certainly not the CCSE. Any ideas?
