我在 Windows 7 64 位笔记本电脑（HP Pavilion g6）上运行 Visual Studio 2010 Professional

非官方 OpenGL SDK： http: //glsdk.sourceforge.net/docs/html/index.html

非官方的 OpenGL SDK、GLew 和 GLee 都是最新的，在适当的地方有匹配的驱动程序、库和头文件

设置：

Preprocessor either over the entire project OR over the main.c file: GLEW_STATIC

Additional Include Directories:
C:/glsdk_0.4.2/glload/include;C:/glsdk_0.4.2/glimg/include;C:/glsdk_0.4.2/glutil/include;C:/glsdk_0.4.2/glmesh/include;C:/glsdk_0.4.2/glm;C:/glsdk_0.4.2/glfw/include;C:/glsdk_0.4.2/freeglut/include;

Additional Library Directories:

Also tried adding C:/Program Files (x86)/Microsoft SDKs/Windows/v7.0A/Lib/glew32s.lib (or glew32, glew32mx & glew32mxs);C:/Program Files (x86)/Microsoft SDKs/Windows/v7.0A/Lib/OpenGL32.lib; in Linker -> Input -> Additional Dependancies

Path Inputs (Changed through Environment Variables. Excluding irrelevant entries):
C:\glsdk_0.4.2\glutil\lib;C:\glsdk_0.4.2\freeglut\lib;C:\glsdk_0.4.2\glfw\library;C:\glsdk_0.4.2\glload\lib;C:\glsdk_0.4.2\glimg\lib;

GLew & GLee lib files are located in:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib
Also tried with them located at:
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib

GLew & GLee header files are located in:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\GL
Also tried with them located at:
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include\GL

从“OpenGL Distilled”复制的代码（标题除外），ISBN10 - 0-321-33679-8：

    #include <stdio.h>
    #include <math.h>

    // Uncomment for GLee ( Also comment out glutInit(&argc, argv); )
    //#include <GL\GLee.h>

    // Uncomment for GLew
    /*#include <GL\glew.h>
    #include <GL\wglew.h>
    #include <GL\glut.h>
    #include <GL\glext.h> */

    // Uncomment for all headers in the "Unofficial OpenGL SDK"
    /*#include <glload\gl_all.h>
    #include <GL\glut.h>
    #include <glload\gll.h>
    #include <glimg\glimg.h>
    #include <glutil\glutil.h>
    #include <glmesh\glmesh.h>
    #include <GL\glfw.h>
    #define FREEGLUT_STATIC
    #define _LIB
    #define FREEGLUT_LIB_PRAGMAS 0
    #include <GL\freeglut.h> */


    int main(int argc, char* argv[])
    {
        glutInit(&argc, argv);

        // Obtain a buffer identifier from OpenGL
        GLuint bufferID = 0;
        glGenBuffers( 1, &bufferID );

        // Bind the buffer object, OpenGL initially creates it empty.
        glBindBuffer( GL_ARRAY_BUFFER, bufferID );

        // Define three vertices to draw a right angle triangle.
        const GLfloat vertices[] = [
            0.f, 0.f, 0.f,
            1.f, 0.f, 0.f,
            0.f, 1.f, 0.f };

        // Tell OpenGL to copy data from the 'vertices' pointer into
        // the buffer object
        glBufferData(GL_ARRAY_BUFFER, 3*3*sizeof(GLfloat), vertices, GL_STATIC_DRAW );
        return 0;
    }

错误：

With GLee:
1>gl_crap3.obj : error LNK2001: unresolved external symbol _GLeeFuncPtr_glBufferData
1>gl_crap3.obj : error LNK2001: unresolved external symbol _GLeeFuncPtr_glBindBuffer
1>gl_crap3.obj : error LNK2001: unresolved external symbol _GLeeFuncPtr_glGenBuffers

With the Unofficial OpenGL SDK:
1>gl_crap3.obj : error LNK2001: unresolved external symbol ___gleBufferData
1>gl_crap3.obj : error LNK2001: unresolved external symbol ___gleBindBuffer
1>gl_crap3.obj : error LNK2001: unresolved external symbol ___gleGenBuffers

With GLew:
1>gl_crap3.obj : error LNK2001: unresolved external symbol ___glewBufferData
1>gl_crap3.obj : error LNK2001: unresolved external symbol ___glewBindBuffer
1>gl_crap3.obj : error LNK2001: unresolved external symbol ___glewGenBuffers

对于 SDK，您的 Visual Studio 项目应具有以下设置（sdkbase您解压缩和编译 SDK 的目录的路径在哪里）。

C/C++->General->Additional Include Directories：

sdkbase\glload\include;sdkbase\glimg\include;sdkbase\glutil\include;sdkbase\glmesh\include;sdkbase\glm;sdkbase\freeglut\include;sdkbase\glfw\include

Linker->General->Additional Library Directories：

sdkbase\glload\lib;sdkbase\glimg\lib;sdkbase\glutil\lib;sdkbase\glmesh\lib;sdkbase\freeglut\lib;sdkbase\glfw\library

Linker->Input/Additional Dependencies, 对于调试版本：

glloadD.lib glimgD.lib glutilD.lib glmeshD.lib freeglutD.lib glfwD.lib glu32.lib opengl32.lib gdi32.lib winmm.lib user32.lib

对于发布版本：

glload.lib glimg.lib glutil.lib glmesh.lib freeglut.lib glfw.lib glu32.lib opengl32.lib gdi32.lib winmm.lib user32.lib

对于不使用非官方 OpenGL SDK 的人，我刚刚遇到了这个问题，感谢 Nicol Bolas 的回答，我意识到我需要 GLEW 的调试库。

对于 Visual Studio，我通过将glew32.lib项目的调试配置 - at linker->input/Additional Dependencies- 替换为glew32s.lib（注意s末尾的）来解决此问题。

在我这样做之后，一切正常。

笔记

虽然您可以在没有此修复的情况下初始化 GLEW 并使用GLEW 特定功能，但一旦您开始调用 OpenGL，您可能会在使用调试符号构建时遇到错误。
