Re: texture_compression weirdness was Re: [PyOpenGL-Users] unable to build PyOpe

Rene,

Below is the three lines I commented out to get PyOpenGl 2.0.1.02 to build.
After seeing Thomas's e-mail I went back to the wrapper code and looked at 
interface/GL/ARB/texture_compression.i  I noticed that for the 
glCompressedTexSubImage* fuctions the declaration in the wrapper did not 
match the headers in glext.h.  Although I have limited experience with swig, 
shouldn't the declarations match? Maybe I will try and change the wrapper in 
my version and see if I can get it to compile or not.

# 3 lines I commented out in GL/glext.h

extern void APIENTRY glCompressedTexSubImage3DARB (GLenum, GLint, GLint, 
GLint, GLint, GLsizei, GLsizei, GLsizei, GLenum, GL
sizei, const GLvoid *);
extern void APIENTRY glCompressedTexSubImage2DARB (GLenum, GLint, GLint, 
GLint, GLsizei, GLsizei, GLenum, GLsizei, const GLv
oid *);
extern void APIENTRY glCompressedTexSubImage1DARB (GLenum, GLint, GLint, 
GLsizei, GLenum, GLsizei, const GLvoid *);

-------------------------------------------------------------------
# Corresponding definitions from interface/GL/ARB/texture_compression.i

DECLARE_VOID_EXT(glCompressedTexSubImage3DARB, (GLenum target, GLint level, 
GLint xoffset, GLint yoffset, GLint zoffset, GLe
num internalformat,\
GLsizei width, GLsizei height, GLsizei depth, GLint border,\
GLsizei imageSize, const void *data),\
(target, level, xoffset, yoffset, zoffset, internalformat, width, height, 
depth, border, imageSize, data))

DECLARE_VOID_EXT(glCompressedTexSubImage2DARB, (GLenum target, GLint level, 
GLint xoffset, GLint yoffset, GLenum internalformat,\
GLsizei width, GLsizei height, GLint border,\
GLsizei imageSize, const void *data),\
(target, level, xoffset, yoffset, internalformat, width, height, border, 
imageSize, data))

DECLARE_VOID_EXT(glCompressedTexSubImage1DARB, (GLenum target, GLint level, 
GLint xoffset, GLenum internalformat,\
GLsizei width, GLint border,\
GLsizei imageSize, const void *data),\
(target, level, xoffset, internalformat, width, border, imageSize, data))

Let me know if you find out anything.

Thanks,

Scott
