OpenGL Linking error

OpenGL OpenGL: Basic Coding
1

Hi all:
I have a program with these headers:

#include <windows.h>
#include <stdio.h>
#include <iostream>

#include <GL/glut.h>
#undef GL_GLEXT_PROTOTYPES
#include <GL/glext.h>
#include <GL/GLAux.h>

#include <glh/glh_extensions.h>
#include <nv_manip/nv_manip.h>
#include <nv_math/nv_math.h>
#include <quitapp.h>


#include <cg/cg.h>
#include <cg/cggl.h>

And I have already added opengl32.lib, glu32.lib, glut32.lib, glaux.lib cg.lib and cgGL.lib in the linker, but I still got these errors when linking:

 WaterDemo.obj : error LNK2001: unresolved external symbol _wglDestroyPbufferARB

WaterDemo.obj : error LNK2019: unresolved external symbol _glh_init_extensions referenced in function "void __cdecl init(void)" (?init@@YAXXZ)

Can anyone help me out? I really dont know what to do.

Hi !

The functions you list are not part of OpenGL 1.1 and are not part of opengl32.lib (this import library comes with windows), to use these functions you need an import library that has them included or use another way to access the extended functions.

There are a number of ways to solve this and if you search this forum you will find lots of information about it.

yep, I already managed to get the code work. :smiley:
