X11 driver not configured with OpenGL on Snow Leopard

[Dominik Reichardt]

Hi all,

since libsdl and libsdl_mixer now are built on SL, I tried my hands on  
compiling Exult (http://exult.sf.net). And indeed it finally builds.  
Exult has world editing program called Exult Studio which uses  
libglade2 and GTK2. When built with support for Exult Studio, Exult  
uses x11 for display and on SL I can't use Exult's OpenGL scaler. When  
I try to use that I get the error (in the console):

Couldn't allocate surface: X11 driver not configured with OpenGL

Does anyone have an idea what the problem is or how to solve this?

Another problem I had was that Exult Studio wouldn't start.
I would get the error "Xlib:  extension "RANDR" missing on display "/ 
tmp/launch-sLK0xy/:0"." in the console and Exult Studio would continue  
to run in the background consuming every CPU time it could get.
Only when I rebuilt cairo and pango with the variants +macosx+quartz 
+universal and GTK2 with universal+x11 (which I was wondering how that  
worked) was  I able to build both Exult and Exult Studio and make  
Exult Studio start correctly (even though it still gives me the error  
"Xlib:  extension "RANDR" missing on display "/tmp/launch-sLK0xy/:0"."  
on startup).
I'd like your input on that as well, even though it is kind of solved  
for now :)

Thanks and take care
