Visual Studio 2013 and OpenGL - c++

Question

I have recently purchased a new laptop and got a new version of VS from my school. And I'm having a little trouble setting up my libraries.
I created a basic SDL_Window, as well as a SDL_GLContext.
I'm able to include my libraries and run the program, but I can't call functions like glClearColor, or glGetString(GL_VERSION). I get a rather strage warning and an error that I have never seen before, I'm guessing it's related to the 2013 version?
I have tried ignoring all specific default libraries, as well as trying to change the programtype (Multithreaded DLL, those 4).
And I have made sure all the dll-files are in place in my system folder.
What makes me wonder is the fact that glewInit() works, but not glClearColor() etc...
Output:
1>MSVCRTD.lib(cinitexe.obj) : warning LNK4098: defaultlib 'msvcrt.lib'
conflicts with use of other libs; use /NODEFAULTLIB:library
1>Window.obj : error LNK2019: unresolved external symbol
