OpenGL OpenGL: Basic Coding

I show you my code.How can i include this code in C++Builder:
#include <stdlib.h>
#include <stdio.h>
#include “glut.h”

static int shoulder=0, elbow=0, coucou=0, poignee=0, pince=0, avant=0, toto=0;/* rectifier*/

void init(void)
{
glClearColor(0.0, 0.0, 0.0, 0.0);
glShadeModel(GL_FLAT);
glEnable(GL_DEPTH_TEST);

GLfloat mat_ambient[] ={0.5, 0.5, 0.5, 1.0};
GLfloat mat_specular[] ={1.0, 1.0, 1.0, 1.0};
GLfloat mat_shininess[] ={50};
GLfloat light_position[] ={1.0, 1.0, 1.0, 1.0};
GLfloat model_ambient[] ={0.5,  0.5, 0.5, 1.0};

glMaterialfv(GL_FRONT, GL_AMBIENT, mat_ambient);
glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, mat_shininess);
glLightfv(GL_LIGHT0, GL_POSITION, light_position);
glLightModelfv(GL_LIGHT_MODEL_AMBIENT,  model_ambient);


glEnable(GL_LIGHTING);
glEnable(GL_LIGHT0);

I had some problems to create an application with C++ Builder that uses GLUT. It is Better to use the Win32 API only without a console window. Take a look at nehe.gamedev.net, there you will find code for C++Builder using the “pure” Win32 API. If you really want to use GLUT, create a new console application: File->New and then on Console Expert or something like this. Then only copy your code into the codewindow. I had only problems and the program never managed to run. Anyway I recommend to use VC++ when using OpenGL. You also find more example projects for it.

Bye and tell me if it worked,
-Stone.

Stonemaster Thank but it doesn’t work with console Application but it work with visual c++ 6.
I must use builder C++ and Nehe’s web page is not available.If you have news answer me.
Nb:My Outlook don’t work

It is a small problem using C++ glut programs and Builder. You can solve it by replacing “#if 0” with “#if 1” somewhere at the beginning of glut.h
