I have read the same topic before,but the problem still existed.I the Visual C++ 6.0,In windows XP I have copied glut32.dll in the folder system32.
1.add glut.h to the folder INCLUDE\GL
2.add glut32.dll ,opengl32.dll to the folder Windows/systems32
3.add glut32.lib ,glut.lib , opengl.lib ,opengl32.lib ,glu.lib to the folder LIB
4.go to the project settings and add glut32.lib glut32.lib ,glut.lib , opengl.lib ,opengl32.lib ,glu.lib
5.#include<glut.h> in my cpp file
the codes from the redbook :
#include <windows.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)
*/
glColor3f (1.0, 1.0, 1.0);
glBegin(GL_POLYGON);
glVertex3f (0.25, 0.25, 0.0);
glVertex3f (0.75, 0.25, 0.0);
glVertex3f (0.75, 0.75, 0.0);
glVertex3f (0.25, 0.75, 0.0);
glEnd();
/* don’t wait!
- start processing buffered OpenGL routines
*/
glFlush ();
}
void init (void)
{
/* select clearing color */
glClearColor (0.0, 0.0, 0.0, 0.0);
/* initialize viewing values */
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}

I don’t konw how to solve the problem .
