I have an X11 application that uses OpenGL. Alas, it's not compiled
for Mac, but rather Linux. So, if I want to display it on my Mac, I
have to "ssh -Y" onto a Linux machine, from an xterm running under
Mac OS X's X11 server.
The problem is that the OpenGL extensions available under this
scenario are fairly limited. If I run "glxinfo" locally, I get one
list of extensions, but if I run it through the ssh connection, I get
a different, shorter list of extensions. My application verifies that
the shorter list is indeed what's available to my application (again,
running via ssh -Y from another machine, but displayed on the Mac).
I have run into similar differences between the availability of
OpenGL extensions when displaying an X11 program locally vs over a
network, even in the case when all the machines involved were
Linux/Unix boxes. However, it was the case that non-ARB extensions
were the only ones not supported across the network.
I don't really understand why there would be such differences, but
what I'm really interested in is finding out of there's any way
around this, or if there's a way to get Apple to "fix" this...
Any help/info/advice would be greatly appreciated...
Thanks!
