SDL&OpenGL under Linux

SDL Development
1

Hi,
i am making something using OpenGL and SDL (almost) everything works
perfect (on my computer) but when i tried to compile&run on school
computer i encoutered little problem.
When calling SDL_SetVideoMode with SDL_OPENGL then thing happens
ERROR! Couldn’t set 1280x1024x32 video mode : X11 driver not configured
with OpenGL

can you help me please? (in XF86Config is this mode enabled :))

Since your problem is an X11 configuration issue, and not an SDL issue, this
isn’t really the proper place to be asking this.> ----- Original Message -----

Is this line a question or a statement?
That mode is enabled, or is this mode enabled?On Wed, 2002-04-24 at 08:33, Krata wrote:

It sounds like when SDL was built on the school computer, the OpenGL
development libraries and headers weren’t available.

You are right sdl was built on school computer but OpenGL was available.
(i hope that flag HAVE_OPENGL means that configure found OpenGL headers)

I am sorry i found it. I had 2 versions of libSDL and the bad one was
used.

available != working

Make sure the OpenGL setup actually works, by trying to run some other
(non-SDL) OpenGL stuff. (If you have the full Mesa package, there should
be some demos, I think…)

‘glxgears’ seems to be “standard”. If it’s installed, XScreensaver
comes with some OpenGL ones.On Thu, Apr 25, 2002 at 04:08:04PM +0200, David Olofson wrote:
