As NBOpenBL gets broader use by end-users of applications like Roassal, there is a good chance of a flood of these reports. Maybe too late to get into Pharo3, but it would good (if possible) for system checking be built in to determine the feature support of a user's graphic card.
Alternatively, such reports might be reduced with better indication its a lack of feature rather than an error. For example: NBGLFrameBuffer(Object)>>unspportedFeature: looks better than : NBGLFrameBuffer(Object)>>error:
What does it changes? This error is going from OpenGL itself. GL_FRAMEBUFFER_UNSUPPORTED is a constant reported by opengl.. are you going to introduce separate error-handling method for each and every possible error code which opengl produces (includes hundreds of extensions and more coming each year) ? If yes, then i wish you good luck! :) The complete error description can be found in corresponding OpenGL documentation. As well as recommendations what to do and what not. And i am not going to teach how to use OpenGL library. ;)

Hi Nicolai,
What are your system specs?, specially your graphic card. Roassal3D requires a graphic card with at least OpenGL 2.0 support. Try updating your graphic drivers

Is there a working version (maybe with examples) for NBOpenGL on Windows?

Thank you Igor,
now the question is, what to do with this? It looks like the same version I would get on installing Roassal3D, which doesn't work (all windows are empty).
Running GLViewportMorph new openInWorld or GLTTRenderingDemo new openInWorld results in an error NBGLFrameBuffer(Object)>>error: 'Frame buffer is incomplete: GL_FRAMEBUFFER_UNSUPPORTED'
so your graphics card/driver don't supports requested configuration of framebuffer used in demo.
all you have to do is to implement own, which will work on your machine. since you got that message, the NBOpenGL works fine.
Nicolai
