Summary: glShaderSource wrapper fail on ATI card ?

Initial Comment:
Hi everyone,

I got a problem on my framework with Shader + ATI card. By switching from pyglet to pyopengl, shader just not working anymore. After investigation, it seem that the wrapper on glShaderSource is not working properly.

If i use the pyopengl wrapper (glShaderSource(shader, source)), i got an error at glLinkProgram() :
Fragment shader was successfully compiled to run on hardware.
Fragment shader(s) failed to link,  vertex shader(s) failed to link.
ERROR: 1:1: error(#132) Syntax error: 'v' parse error
ERROR: error(#273) 1 compilation errors.  No code generated
ERROR: 1:1: error(#132) Syntax error: 'v' parse error
ERROR: error(#273) 1 compilation errors.  No code generated

If i'm doing ctype myself like:
glShaderSource = platform.createBaseFunction( 
    'glShaderSource', dll=platform.GL,
    resultType=None, 
    argTypes=(constants.GLhandle, constants.GLsizei, ctypes.POINTER(ctypes.c_char_p), arrays.GLintArray,),
    doc = 'glShaderSource( GLhandle(shaderObj), str( string) ) -> None',
    argNames = ('shaderObj', 'count', 'string', 'length',),
)

from ctypes import *
source = c_char_p(source)
length = c_int(-1)
glShaderSource(shader, 1, byref(source), byref(length))

-> no more error message at glLinkProgram.

Where i can debug more the wrapper function ? Is it a converter problem ?

Thanks,

Mathieu

Note: i'm running the 3.0.0-0ubuntu1 from Ubuntu Karmic.
