Re: [PyOpenGL-Users] PyOpenGL crash on Intel HD 3000

[Cyrille R. <cyr...@gm...>]

Some precisions that may be useful:

  * the same script works fine on other machines
  * glGetString(GL_VERSION) returns OpenGL 3.1
  * same crash with PyQt4 or GLUT
  * same crash with a bunch of different GL commands, like
"glGetStringi(Gl_EXTENSIONS, 0)"

Here is the script:

import sys
from OpenGL.GLUT import *
from OpenGL.GL import *
from OpenGL.GLU import *

def init():
    buffer = glGenBuffers(1)

glutInit(sys.argv)
glutInitWindowSize(600, 600)
glutCreateWindow("Sample")
init()
glutMainLoop()

Thanks for your help.
