Hi all, i decide to build JOGL with the updated glext.h. With all unnamed structs like _cl_event, _cl_context, __GLSync etc (which are commented out in jogl official glext.h) deleted, things are still not going well. I get this:

java.lang.RuntimeException: Error while generating bindings for "void glDebugMessageCallback(void (*callback)(GLenum source, GLenum type, GLuint id, GLenum severity, GLsizei length, const GLchar *  message, GLvoid *  userParam), const void *  userParam);"

for your ref, the definition of GLDEBUGPROCARB is

typedef void (APIENTRY *GLDEBUGPROCARB)(GLenum source,GLenum type,GLuint id,GLenum severity,GLsizei length,const GLchar *message,GLvoid *userParam);

However, in the JOGL's glext.h, all functions and definitions related to GLDEBUGPROCARB are the same as mine. This makes me very confusing.

I hope someone who are experienced with GlueGen can give me some answers.

Thanks sincerely
