Re: [Haskell-cafe] Code from Haskell School of Expression hanging.

Ok, in the GLFW sample program from Haskell Wiki, can you change the GLFW.openWindow line to the following, and try again? GLFW.openWindow (GL.Size 400 400) [GLFW.DisplayStencilBits 8, GLFW.DisplayAlphaBits 8] GLFW.Window Does it still run? Regards, Paul Liu On Sun, Jan 30, 2011 at 10:50 AM, michael rice wrote:

What you see below is what I get. No window opens. System Monitor shows CPU usage negligible.

I'm the maintainer of the SOE code. This is rather puzzling, since apparently GLFW works on your setup. I don't think there is much big difference in SOE than the sample GLFW program from the Haskell Wiki. So when you run the SOE program, did you see the window but just all blank? Or you never see the window popping up? Regards, Paul Liu

The sample program (the "active" version) here runs fine, so  the OpenGL GLFW must have been installed properly. Must be the SOE stuff causing the problem.

I'm using the OpenGL stuff (GLFW). Same set of problems?

No idea, I haven't used a graphics library for a long time.
