OpenGL random externalAccessFailed in 64bit ?

Hi,

I try to simplify the way to reproduce the problem :

I Create a new 64 bit image 7.9.1, load the OpenGL.Lessons parcel,

and run the Lesson 00.

Image Rendering:

Then External access fails :

Unhandled exception: External access failed

WGL.WGLInterface(ExternalInterface)>>externalAccessFailedWith:

WGL.RenderContextWin32Pixmap>>initializeHDC

stack dump is in attached file.

Either there aren't 64bit opengl drivers available or I have some struct size incorrect somewhere in the external interface (I hope not). I'm not sure where you should start debugging. If I were to do it, I'd be comparing a basic C program to the Smalltalk structures to see that they're all the same and that it should work.

Cheers,
Michael
