[Xquartz-dev] Where's libGL

[Jeremy Huddleston]

GL is a bit of a sore spot in the server.  What bugs are you talking  
about specifically, and can you send us your fixes?

*cough*

This is the downside of Open Source -- you get to see the places I had  
to use duct tape to hold this all together.
The X server has a dependency on Mesa (hence --with-mesa-source=....),  
and libGL.dylib is (nominally) built out of the Mesa source, so   it  
makes the most sense to build it there even though it's a library.   
So, it's built as part of X11server:

http://www.opensource.apple.com/darwinsource/10.5/X11server-46/build

But wait!  There's more!   That version support AIGLX, but not  
AppleDRI.  Late during Leopard's development, we realized we had to  
support AppleDRI, so I copied in the patched Mesa from Tiger, and we  
build that, and we install that (and throw away the copy we built from  
Mesa-6.5.2).

The right way to fix this would be to merge the Apple patches against  
the Mesa that came with Tiger into the mainstream Mesa distribution,  
but I couldn't figure out how to do this.  I spoke briefly with the  
Mesa peeps about this -- http://www.nabble.com/adding-AppleDRI-support-to-Mesa3D--t4419462.html 
  -- but while they felt it would be easy, I spent a week trying and  
failed.

"""

The 1.2/1.3 branch of xorg-server needs Mesa-6.5.2.  The 1.4 branch  
can use the latest release of Mesa (7.0.2).  We're currently trying to  
squish out regressions on the 1.4 branch over 1.2/1.3 since 1.4 should  
solve some of our fb related crashes and get us more current with  
mainline.  Once that's done, we can try getting Mesa 7.0.2 working  
nicely.

All the Apple-specific changes are in git.freedesktop.org except these  
three patches which Ben hasn't pushed in yet:

Ben, should I push in the xcb patch?  Also, why did you remove the  
poll check from libXt?
