I’m a begginer to opengl. I want to compile and run sample code on my machine. (I have 2 machines one had GeForce 4 MX and other got Sis 6326 ).
Is it possible to me to run opengl on my mach ines?
Tell me how to compile folowing code and runit Or send me a Makefile
#include <GL/gl.h>
#include <GL/glut.h>
void display(void)
{
/* clear all pixels /
glClear (GL_COLOR_BUFFER_BIT);
/ draw white polygon (rectangle) with corners at
- (0.25, 0.25, 0.0) and (0.75, 0.75, 0.0)

/ - Declare initial window size, position, and display mode
- (single buffer and RGBA). Open window with “hello”
- in its title bar. Call initialization routines.
- Register callback function to display graphics.
- Enter main loop and process events.
