I just wanted to provide some more information on ticket #122 (http://xquartz.macosforge.org/trac/ticket/122
),
I notice people have had trouble getting wine to detect libGL at all,
but I won't go into that as the issue is related
to dlopen() but imo using the DYDL_FALLBACK_PATH env is the wrong way
to fix it.
Once you can get wine to find your libGL as in this ticket it will say:
err:wgl:has_opengl glx_version is 1.2 and GLX_SGIX_fbconfig extension
is unsupported. Expect problems.
Now at this point wine does NOT make any bindings to any of the
required GLX functions, so any crashes or
problems after this point are likely not a GLX issue but rather the
fact that wine is calling function pointers that
haven't been set to anything!
So the first check wine does is "glxRequireVersion(3)", which fails
since the current version reports itself as 1.2,
wine will then try a call to
"glxRequireExtension("GLX_SGIX_fbconfig")", this check ALSO fails.
Even though a
check on the libGL provided shows that it contains symbols for
GLX_SGIX_fbconfig.. When both of these checks
fail the function pointers to:
Don't get set, so obviously it's not going to work too well..
At this point I decided to just hack wine to bind to the extensions
anyway, since they appeared to exist in the
supplied libGL. This works without error, leading me to believe that
"glxRequireExtension("GLX_SGIX_fbconfig")"
is failing to report correctly that the extension is supported..?
How ever the app I tested with still was unable to draw in openGL, due
to any call made to glXMakeContextCurrent
was returning false.. It was able to create a context and also delete
it though..
Hope this helps.. And if anyone has ideas on why the
MakeContextCurrent is failing please let me know!
Cheers!
