Re: [PyOpenGL-Devel] pyopengl and pypy, one step further

i'm back again with some news: shaders are now working, it required a minor fix
of the StringLengths CConverter (in OpenGL/converters.py). the stringArrayForC 
method requires an explicit cast to make pypy ctypes version happy:

     def stringArrayForC( self, strings ):
         """Create a ctypes pointer to char-pointer set"""
         from OpenGL import arrays
         result = (ctypes.c_char_p * len(strings))()
         for i,s in enumerate(strings):
-            result[i] = arrays.GLcharARBArray.dataPointer(s)
+            result[i] = ctypes.cast(arrays.GLcharARBArray.dataPointer(s),
                                     ctypes.c_char_p)
         return result


now, the following programs run fine:
- 05-shader.py (partial shader-based implementation of the fixed pipeline)
- 06-perpixel.py (per-pixel lightening)
- 07-attrib.py (generic vertex attributes rather than pointers)
- 08-pbo.py (using pixel buffer object to read back pixels from framebuffer)

the last one does opengl à la opengles (without any fixed functionality) but
does not work yet.
this time, i think that it's pypy's fault :)

stay tuned,
