[PyOpenGL-Users] pyopengl on the OpenMoko FreeRunner

[Gunnar A. G. <gun...@df...>]

Hi all,

I am trying to get pyopengl to work on the openmoko FreeRunner [1]
Building the package and installing was fairly straight forward, but
running my fairly simple example gives me:


Traceback (most recent call last):
  File "largepic.py", line 58, in <module>
    screen = lamina.LaminaScreenSurface()
  File "/home/root/mokotoys/lamina.py", line 221, in __init__
    self.setup()
  File "/home/root/mokotoys/lamina.py", line 226, in setup
    self.refreshPosition()
  File "/home/root/mokotoys/lamina.py", line 232, in refreshPosition
    bottomleft = oglu.gluUnProject(0, 0, depth)
  File "/usr/lib/python2.5/site-packages/OpenGL/lazywrapper.py", line
32, in __call__
    return wrapper( baseFunction, *args, **named )
  File "/usr/lib/python2.5/site-packages/OpenGL/GLU/projection.py", line
46, in gluUnProject
    model = GL.glGetDoublev( GL.GL_MODELVIEW_MATRIX )
  File "/usr/lib/python2.5/site-packages/OpenGL/wrapper.py", line 1631,
in __call__
    return self.finalise()( *args, **named )
  File "/usr/lib/python2.5/site-packages/OpenGL/wrapper.py", line 683,
in wrapperCall
    converter( pyArgs, index, self )
  File "/usr/lib/python2.5/site-packages/OpenGL/converters.py", line
195, in __call__
    return self.arrayType.zeros( self.getSize(pyArgs) )
  File
"/usr/lib/python2.5/site-packages/OpenGL/arrays/arraydatatype.py", line
98, in zeros
    return cls.returnHandler().zeros( dims, typeCode or cls.typeConstant )
  File "/usr/lib/python2.5/site-packages/OpenGL/arrays/nones.py", line
32, in zeros
    raise TypeError( """Can't create NULL pointer filled with values""" )
TypeError: ("Can't create NULL pointer filled with values", 'Failure in
cConverter <OpenGL.converters.SizedOutput object at 0x40ffcfb0>',
[GL_MODELVIEW_MATRIX], 1, <OpenGL.wrapper.glGetDoublev object at
0x4100a698>)


Now, before I dive in and debug this - let me ask: Has anyone else had
any success with pyopengl on the ARM architecture?

Some of the tests from the pyopengl run successfully, but most GLUT ones
fail with because of some missing font - and test_loadglut fails with :
AttributeError: python: undefined symbol: glutSolidTeapot

The FreeRunner has libGL, libGLU from MESA version 6.5, is this too old?


Please reply also to me offlist as I am not subscribed.

Thanks!
