First: I’m sorry for my bad english. I’m brazilian and don’t speak very well.

I’m trying to compile a project with glfw in Visual Studio Expreess 2005 and I have some link errors:

Big list, isn’t!?

Someone can help me?

It looks like you aren’t linking with the OpenGL and GLFW libraries. If that’s the case, add opengl32.lib and glfw.lib to the Input section of the link settings in your project, and make sure Visual Studio knows where to find the GLFW library.
