What is the relation between the libGL in X11 and the OpenGL framework

libGL links against OpenGL.framework. The glFoo entrypoints seen by X11
applications are those exported by the framework.
for example, I have a package (OpenSceneGraph) which links against
the framework. I now want to use Qt (the GUI from Trolltech) which
is an X11 distribution (I don't have the native Qt). For now, I just
changed OpenSceneGraph to link against the X11 libGL. However, can
one use X11 with apple OpenGL framework ? and what if GLX is also
required ?
I'm not exactly sure what you're trying to do. But if you're trying to
take a native GL app and make it into an X11 GL app by linking against
libGL instead of OpenGL.framework, that isn't going to work
does the OpenGL framework has more features then X11 libGL ? for
example
the X11 does not have offscreen rendering. I'm not sure about the
framework.
Yes, the OpenGL.framework supports offscreen rendering, but currently
X11 doesn't,
