Hi!
I have a problem using OpenGL with SDL 1.1 under Linux. I have installed
the Mesa3.1 libs, tried the demos and everything worked perfectly. But
if I compile the gltest demo of SDL and run it, it says that the x11
driver is not configured for OpenGL. I have defined HAVE_OPENGL but it
doesnt change anything. This is probably a newbie question, but anyway I
played around for a while ( recompiled the SDL source with -DHAVE_OPENGL
and used the new libs etc…), but it still doesn’t work. So if someone
could please tell me a potential cause I’d be very grateful!
thx!

hi`
do other GL apps like glinfo work?

Hmm. Did you alias your libraries so that in /usr/lib (I think!) you have:
libGL.so.1.0.2 (or whatever it is)
and libGLU.so.1.0.2?
Mesa links to libMesaGL, so the test programs will work. SDL looks for libGL,
the standard name for the GL library. Have a gander through README.X11,
included in your Mesa 3.1 distribution, for hints on how to properly create
symbolic links.
If this doesn’t fix the problem, post back again and we can have another whack
at it.

Okay, what does locate SDL tell you? Maybe you have some older version
of SDL installed somewhere that defaults to not use OpenGL. Btw, the
configure option is --enable-video-opengl and defaults to true. If you
compile with -DHAVE_OPENGL it shouldn’t write “X11 driver not configured
with OpenGL” as the code isn’t compiled in. Well, so I guess you have
several versions of SDL lying around.–

When you configure SDL, does it say something like:
checking for OpenGL (GLX) support… yes

This is because it didn’t detect OpenGL. Re-configure SDL now that
Mesa is installed.

That was right, but I de installed the 1.0.4 version using GnoRPM, and the
libraries should
already be 1.2 anyway because I changed the links to the new lib. Is there
anything special I have to change to make 1.2 the current version?>

It does detect OpenGL when configuring. I recompiled it and replaced the
libraries but no change again.> On Mon, Feb 28, 2000 at 05:37:39PM +0100, Martin Kremecek wrote:
