graphics programing in linux

my hobby is programing graphics in c language. i am fully familiar with c in dos mode. recently i started to work on linux and i like it. but i could not run any "graphics program in linux"

with or without using graphics.h. other than using ascii characters on screen mode..

could you please brief up how graphics programing in c for linux is done.

    If you like to play with graphics I would suggest you to

    start with OpenGL. It is real fun to program and there are plenty of

    examples out there for free. But first you have to figure out whether you

    have Mesa lib or not. Check in /usr/lib/ there must be Mesa-x.x where x.x is

    a version.

    here is files you may want to get from net:

    Mesa-demos-3.0-2.i386.rpm

    Mesa-devel-3.0-2.i386.rpm

    Mesa-glut-3.0-2.i386.rpm

    Mesa-glut-devel-3.0-2.i386.rpm

    --------------------------------------

    For you to start here is a small example:

    Save it as x.c or x.cpp where x is name you like and than compile by the following command:

    For x.c use

    cc x.c -lglut -lMesaGLU -lMesaGL -L/usr/X11/lib -L/usr/X11R6/lib -lX11 -lXext -lXmu -lXt –lXi



    For x.cpp use

    g++ x.cpp -lglut -lMesaGLU -lMesaGL -L/usr/X11/lib -L/usr/X11R6/lib -lX11 -lXext -lXmu -lXt -lXi



    Later you have to decide which X lib you have to use during compilation but now I show you most common lib.
