Also upon further reflection, it seems that in wxglcanvas, it doesnt actually error, but the textures arent loaded and a blank black texture is used anyway. I had a hard time seeing this because the texture image itself is almost black.
Thanks again for your help.

the error you originally sent shows 750 as the width and height arguments to glTexImage2D on the exception- 750 is not a power of 2. Hence you were trying to use non-power of 2 textures. To make it use of power-of-2 you'd have to either put that 750 wide & high image in some bigger texture (i.e. scale it up or black box it) or split it across multiple textures.
As far as what is different between pygame display and wxglcanvas, I don't know - is it still the same size for the window for both? Are there possibly some calculations that are different with your different code related to texture size? Also the problem could be something else other than texture size (maybe something with the texture format not being supported, or maybe the driver didn't like some of the texture contents?) that would be related to how the GL context was created...

Thanks for the reply.
Here is where it gets wierd.
I have modified the script to not use a pygame display. Instead it uses a wxglcanvas on a wx frame/notebook. Compiled using the same parameters but still use pygame to load the image.
That one worked fine compiled or not in any machine.
So im willing to discount anything from py2exe. Since it is a pygame display, i was wondering what is different about it? or how do i check if im using a non power-of-2 texture or convert my textures so that it can work?
Thanks again for your help.

It seems the system that has the problem must not like something about the way glTexImage2D was called in that case - GL errors like you see there come from the drivers. I would guess that it is that you are using a non power-of-2 texture size (a bad thing to do if you didn't explicitly check for support and you care at all about compatibility)

Hi,
I have a python script that uses wx, pygame and pyopengl. I've combined wx and pygame similar to http://wiki.wxpython.org/IntegratingPyGame (in windows) and the pygame has a separate thread. The pygame part of it uses pyopengl for a display window and to load images. When I create a .exe from this script, the executable works fine on the pc that i compiled it on (my one), but it wont run anywhere else; even ones that are almost identical build to mine (it doesnt have python, pygame or pyopengl installed). It gives me a wierd error that I dont know what it means. Does anyone know what might cause it? or how do I debug these problems? Why would it work on my pc and not anywhere else?
Thanks for any help
It gives me the following error:
