希望大家帮帮忙啊下面这个有关问题是在VC++ 6.0下编写的OpenGL函数。多谢

希望大家帮帮忙啊，下面这个问题是在VC++ 6.0下编写的OpenGL函数。谢谢。
#include <iostream.h>
#include <windows.h>
//#include <stdio.h>
#include <conio.h>
#include <gl/gl.h>
#include <gl/glu.h>
#include <gl/glaux.h>

void   main(void)
{
auxInitDisplayMode(AUX_SINGLE|   AUX_RGBA);
auxInitPosition(0,0,500,500);
//auxInitWindow( "simple ");

glClearColor(0.0f,0.0f,0.0f,0.0f);
glClear(GL_COLOR_BUFFER_BIT);

//glColor3f(1.0,0.0,0.0);
//glRectf(-0.5,-0.5,0.5,0.5);

glFlush();
//_sleep(1000);
cprintf( "please   any   key   to   close   the   window\n ");
getch();
}
此程序能通过编译，但在执行时出错了，具体情况如下：
Linking...
d.obj   :   error   LNK2001:   unresolved   external   symbol   __imp__glFlush@0
d.obj   :   error   LNK2001:   unresolved   external   symbol   __imp__glClear@4

执行   link.exe   时出错.
