Re: [Visualpython-users] gl_extensions compile error

It looks to me like you have pointers to one type of function and are
trying to use them as pointers to a different type of function:

from void (*)(GLenum, GLint, GLint,  GLsizei, GLsizei, GLsizei, GLint, GLenum, GLenum, const GLvoid*)
to   void (*)(GLenum, GLint, GLenum, GLsizei, GLsizei, GLsizei, GLint, GLenum, GLenum, const GLvoid*)

Note that the 3rd argument is GLint in one case and GLenum in the other.
