Package: libsdl1.2debian
Version: 1.2.10-3
Severity: normal
Tags: patch
Nexuiz uses SDL's OpenGL stuff, but HW acceleration doesn't work. It
works fine with other games that use OGL directly. Glxinfo also
shows that HW acceleration is activated.
What's happening:

`-----------
So it tries to load r300_dri, but it doesn't work, because there are
missing symbols. After a bit of googling I found this:
http://www.mail-archive.com/[email protected]/msg26006.html
The workaround proposed there (preloading libGL.so.1) actually
works.
Looking at the source, SDL really uses dlopen() without RTLD_GLOBAL.
X11_GL_LoadLibrary() calls SDL_LoadObject(), and on Linux the
implementation in src/loadso/dlopen/SDL_sysloadso.c is used. There
we can see:
,-----------
| void *handle = dlopen(sofile, RTLD_NOW);
`-----------
As Drepper writes[1], using RTLD_GLOBAL generally isn't a good idea,
but libGL seems to require it:
http://dri.sourceforge.net/doc/DRIuserguide.html#s11
So the attached patch introduces a new static function
SDL_LoadObject_LibGL() in src/video/x11/SDL_x11gl.c, which does the
same as SDL_LoadObject, but uses RTLD_GLOBAL. If SDL_LOADSO_DLOPEN
is not defined (i.e. not the dlopen SDL_LoadObject implementation is
used, but another one), the patch doesn't touch anything.
It fixes the bug for me and shouldn't cause any other problems
AFAICS.
After writing all this I see that there's a simmilar patch in the
SDL svn repository, cf. commit 2523:
http://www.libsdl.org/cgi/viewvc.cgi/trunk/SDL/src/video/x11/SDL_x11gl.c?view=log
Would be nice if you could apply either one of the patches to fix
this problem, thanks.
Cheers,
Christian Aichinger
