glFramebufferTexture2D in early version of opengl(vertex)

[mbikos]

Hi guys!
I want to be able to use glFramebufferTexture2D in order to create a FrameBuffer Object(FBO) and render my entire current opengl scene to a texture of an FBO.(just like in this tutorial

However I am using an earlier version of openGL(no shaders at all-only vertices etc) and glut and gl.h can't find the command glFramebufferTexture2D at all.What can I do to achieve this in OpenGL early versions(no shaders)? Should I include glew.h too? And If I do can I continue writing my program or do I have to create shaders etc?
