[squeak-dev] [BUG]OGLWin32(Object)>>error:Nicolas Cellier nicolas.cellier.aka.nice at gmail.comThu Mar 1 22:01:20 UTC 2012
Most probably, some library was not found (I see the handle is 0).
If I open a browser on OGLWin32
OGLWin32 browse.
In class definition, you see that handle is an instance variable.
Then looks at instance variable assignment (menu assignment... or
CTRL+a in class pane)
I get these two methods
OpenGL>>destroy
OpenGL>>initializeIn: bounds
handle := self primCreateRenderer: 1 "B3DSoftwareRenderer" + 2
"B3DHardwareRenderer" + 4 "B3DStencilBuffer"
x: bounds left y: bounds top w: bounds width h: bounds height.
bufRect := bounds.
handle ifNotNil:[glExt := OGLExtManager new ogl: self].
^handle ifNotNil:[self]
If I browse implementors of primCreateRenderer:x:y:w:h:, I get
OpenGL>>primCreateRenderer: flags x: x y: y w: w h: h
<primitive: 'primitiveCreateRendererFlags' module:'B3DAcceleratorPlugin'>
^nil
It could be that your VM does not have the optional module
B3DAcceleratorPlugin...
I see you are using Squeak 4.1, and don't remember if it was already
available...
But you could search for top menu bar item help->about this system.
If you have it, in the resulting window, select VM Modules and report
if B3DAcceleratorPlugin was loaded.
Also select VM General and report your results.
If you don't have this tool, then try
SmalltalkImage current listBuiltinModules , SmalltalkImage current
listLoadedModules.
and
SmalltalkImage current vmVersion.
