GLew/ GLee/非官方OpenGL SDK的VS2010链接错误

Question

我在Windows7 64位笔记本电脑(HP Pavilion g6)上运行Visual Studio2010专业版

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，在适当的地方都有匹配的驱动程序、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:
C:/glsdk_0.4.2/glload/lib;C:/glsdk_0.4.2/glimg/lib;C:/glsdk_0.4.2/glutil/lib;C:/glsdk_0.4.2/glmesh/lib;C:/glsdk_0.4.2/glfw/library;C:/glsdk_0.4.2/freeglut/lib;

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

        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 ___glewGenBuffers

Answer 1

对于SDK，您的Visual Studio项目应该具有以下设置(其中sdkbase是您解压并编译SDK的目录的路径)。

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，用于调试版本：

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

Answer 2

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

对于Visual Studio，我修复了这个问题，将项目调试配置中的glew32.lib -在linker->input/Additional Dependencies中-替换为glew32s.lib (注意末尾的s )。

在我这样做之后，一切都运行得很好。

便笺

虽然您可以在没有此修复的情况下初始化GLEW并使用GLEW特定函数，但是一旦您开始调用OpenGL，在使用调试符号进行构建时，您可能会收到错误。
