我正在尝试做 openGLbook.com 教程。我收到这个常见错误：

我从 glew.sourceforge.net 下载了最新的 GLEW 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。
我正在使用 VS 2010。以下是我更改的设置（基于其他线程和论坛）：
1) 属性 > VC++ 目录........添加了包含 glew.h 和 freeglut.h 的“include”文件夹
2）属性>链接器>输入>附加依赖.....添加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，我正在使用与 C 驱动器不同的驱动器工作。即使我将所有内容都链接到属性中的正确文件夹，这是否会产生影响？
