opengl - GLEW 链接错误

Question

我正在尝试做 openGLbook.com 教程。我收到这个常见错误:

    1>------ Build started: Project: OpenGL Startup, Configuration: Debug Win32 ------

我已经从 glew.sourceforge.net 下载了 GLEW 的最新 64 位二进制文​​件，并将它们复制到 C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A 中的相应位置。我还下载了最新的 freeglut 文件并做了同样的事情。

我使用的是 VS 2010。以下是我更改的设置(基于其他主题和论坛):

1) Properties > VC++ Directories........ 添加了包含 glew.h 和 freeglut.h 的“include”文件夹

2) Properties > Linker > Input > Additional Dependencies..... 添加了 glew32.lib, freeglut.lib, glew32mx.lib, glew32mxs.lib, glew32s.lib

我真的不明白为什么它仍然没有正确链接库。我还应该注意，我在与 C 驱动器不同的驱动器上工作。即使我将所有内容都链接到属性中的正确文件夹，这也会产生影响吗？

编辑:忘记发布实际代码，这里是:

#include <stdlib.h>

    }

    FrameCount = 0;
    glutTimerFunc(250, TimerFunction, 1);
}

如果您已经弄明白了，我很抱歉。我也没有花时间阅读评论。但是，您正在链接到静态库 glew32s.lib，但您的代码顶部没有包含您的包含项的#define GLEW_STATIC。

试试吧。我很确定那是你的问题。我尝试在我的代码中注释掉该行，但遇到了类似的错误。
