OpenGL Initilisation problem on Linux

SDL Development
1

After installing Mesa3D on a Linux system, distro - Vector Linux 4, I tried compiling a simple SDL program, trying to initialise OpenGL.

I get an error which says “Couldn’t find matching GLX visual” when SDL_OPENGL is passed as one of the initialisation flags.

Mesa3D is properly installed, so what could possibly be wrong and how can I solve the problem?

You should run “glxinfo” to see which opengl pixel formats are
supported. The fact that you get "Couldn’t find matching GLX visual"
means that GLX can’t find a mode matching the required among the listed
video modes. To specify the pixel mode you want, you should use
SDL_GL_SetAttribute() command.

Problem solved.

After running glxinfo, I discovered that I had used SDL_GL_SetAttribute
to set the values higher than it should have been.

Thanks.
