py2exe和PyOpenGL

Question

I have tried using py2exe to make an executable of my PyOpenGL project, and I did... The problem is, it is not running... The exe is not running and i am getting this log:

Traceback (most recent call last):
File "gl.py", line 1, in <module>
ImportError: No module named OpenGL.GL

setup.py looks like this:

from distutils.core import setup
import py2exe

setup(windows=['gl.py'],
      options={
          "py2exe": {
              "includes": ["ctypes", "logging"],
              "excludes": ["OpenGL"],
              }
          }
      )

My project looks like this:

Does anyone know what might be causing this problem?

Answer 1

When you exclude the package in py2exe you need to then manually add it to the resulting "dist" directory. That is, you would copy the whole of the OpenGL package from your site-packages directory into the py2exe dist directory.

I've done an experiment with PyOpenGL 3.1.0b2 and py2exe using explicit includes such that only those parts of PyOpenGL you use are included. The results are written up in a blog post . For your purposes (using Pygame) you shouldn't need to worry about the lack of GLUT/GLE DLLS, and on a real Win32 machine it may simply work as expected (the tests failed on my VM).
