title: Cant compile any opengl/freeglut/glut source code
body: <p>I have this code which i took from an opengl example code:</p>
  
  <pre><code>#include &lt;GL/glut.h&gt;
  
  // Display callback ------------------------------------------------------------
  
  void display()
  {
      // clear the draw buffer .
      glClear(GL_COLOR_BUFFER_BIT);   // Erase everything
  
      // set the color to use in draw
      glColor3f(0.5, 0.5, 0.0);       
      // create a polygon ( define the vertexs) 
      glBegin(GL_POLYGON); {           
          glVertex2f(-0.5, -0.5);
          glVertex2f(-0.5,  0.5);
          glVertex2f( 0.5,  0.5);
          glVertex2f( 0.5, -0.5);
      } glEnd();
  
      // flush the drawing to screen . 
      glFlush(); 
  }
  
  // Keyboard callback function ( called on keyboard event handling )
  void keyboard(unsigned char key, int x, int y)
  {
      if (key == 'q' || key == 'Q')
          exit(EXIT_SUCCESS);
  }
  
  // Main execution  function 
  int main(int argc, char *argv[])
  {
      glutInit(&amp;argc, argv);      // Initialize GLUT
      glutCreateWindow("OpenGL example");  // Create a window
      glutDisplayFunc(display);   // Register display callback
      glutKeyboardFunc(keyboard); // Register keyboard callback
      glutMainLoop();             // Enter main event loop
  
      return (EXIT_SUCCESS);
  } 
  </code></pre>
  
  <p>it should work right?
  but when i run it:</p>

  <p>I installed opengl, freeglut correctly (i mean, it runs and vc++ find's it no problem),
  but i cant run any source code i find.. (same error's)</p>
