回答1:
You seem to be using some form of library that wraps GL entrypoints (the entrypoints you list are not direct GL entrypoints).
This library (GLEE ?) likely is coming with a .lib file that you need to link against.
Coming from the project page of GLEE (my guess, based on a quick googling of who is using the prefix p for GL calls):
Usage examples
To use GLee, include GLee.h, then simply link to GLee.lib or alternatively add GLee.c to your project.

You have to link your program against opengl32.lib, see here.

I recommend you start using GLEW since OpenGL > 1.5 on Windows is a bit of a pain in the ass. This will get you all OpenGL entry points without messing with extension pointers.
