hi im doing an openGL project but after downloading and installing the glut library files it still wont compile and i get 12 error C3861: identifier not found, any help would be great

the glut32.dll file is in my system32 folder
glut32.dll 文件在我的 system32 文件夹中
my glut.h file is in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include
我的 glut.h 文件在 C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include
and my glut.lib file is in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib
我的 glut.lib 文件在 C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib
UPDATE added and now i have these errors

This problem resulted from wrong .lib linking.
这个问题是由错误的 .lib 链接引起的。
In Project's properites, choose: Configuration properties -> linker -> input
在 Project 的属性中，选择：配置属性 -> 链接器 -> 输入
in the right column choose: additional dependencies, add following libraries to the list, seperated by semi colon: opengl32.lib ; glut32.lib ; glu32.lib ;
在右栏中选择：附加依赖项，将以下库添加到列表中，以分号分隔： opengl32.lib ；glut32.lib ; glu32.lib ;
This will solve the problem.
这将解决问题。

Only use #include <glut.h>
只使用 #include <glut.h>
GLUT contains all the gl.h functions anyway. just make sure that in the project settings you set all the dependancies for glut32.lib, openGL32.lib etc.
无论如何，GLUT 包含所有 gl.h 函数。只需确保在项目设置中为 glut32.lib、openGL32.lib 等设置了所有依赖项。

i created a video on how to set up glfw. it was 20 minutes of pain, but finally got it to work. http://www.youtube.com/watch?v=dpsC4kP2ME0visual studio 2010 seems to be very sensitive to configuration, make sure configuration is set to "all configurations".
我创建了一个关于如何设置 glfw 的视频。痛苦了 20 分钟，但终于让它起作用了。 http://www.youtube.com/watch?v=dpsC4kP2ME0Visual Studio 2010 似乎对配置非常敏感，请确保将配置设置为“所有配置”。
