OpenGL编译问题

Question

I am using Visual Studio C++ and GLEW. The Project Settings are all set (Includes/Libs).

MenuState.obj : error LNK2001: unresolved external symbol __imp____glewUseProgramObjectARB
MenuState.obj : error LNK2001: unresolved external symbol __imp____glewLinkProgramARB
MenuState.obj : error LNK2001: unresolved external symbol __imp____glewAttachObjectARB
MenuState.obj : error LNK2001: unresolved external symbol __imp____glewCompileShader
MenuState.obj : error LNK2001: unresolved external symbol __imp____glewShaderSource
MenuState.obj : error LNK2001: unresolved external symbol __imp____glewCreateShader
MenuState.obj : error LNK2001: unresolved external symbol __imp____glewCreateProgramObjectARB

These are the only Messages I get. Everything worked fine until I tried to implement a Shader. The Problem is I am working within a VM, so my question is: Does GLEW need opengl32.lib as a dependency? Because if I dont add the opengl32.lib to the Linker I get even more errors. And if so could the Problem be caused by the opengl32.lib? Because I think the opengl32.lib is the standard windows opengl32.lib, that would mean it's only opengl 1.1, and therefor it can't link...

So what is the issue about these errors?

Make sure to #define GLEW_STATIC in the project before including GLEW in Windows. Then you can just include the entire source code in your project files. Otherwise, you need to have the proper GLEW DLL file in with your executable.
