The easiest way to get started is with GLUT

int main(int argc, char *argv[])
{
        glutInit(&argc, argv);
        glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
        glutInitWindowSize(640, 480);
        glutCreateWindow(argv[0]);
 
        /* Initialise stuff */
        init();
 
        /* Register callbacks */
        glutDisplayFunc(displayCallback);
        glutMouseFunc(mouseCallback);
        glutIdleFunc(idleCallback);
 
        glutMainLoop();
        return 0;
}

Here's a simple Makefile:

CFLAGS = -Wall  -I/usr/X11R6/include/ -O2 -g
 
LDFLAGS = -L/usr/X11R6/lib -lGL -lGLU -lglut
 
PROG = my_executables_name
 
SRC = main.c somethingelse.c blah.c
 
OBJ = $(SRC:.c=.o)
 
all: $(PROG)
 
$(PROG): $(OBJ) Makefile
        $(CC) -o $@ $(OBJ) $(LDFLAGS)
 
$(OBJ): Makefile

Hope this helps

You can use:

- Plain X commands, not difficult but not very friendly

- Use a third party library: glut or better, SDL, the last version (1.1.5) is really better than GLUT (true full screen, can change video mode, advanced event handling, sound support etc...). Check it at: http://www.libsdl.org/

Doh! How could I forget to mention
the fine SDL library? :P

Just to second what MC says,
yes, SDL is also a good thing to use to
quickly get started.
