Hello, i am basically the exact same as u, new to SFMl and new to C++, but with your linker problems are you linking sfml-graphics.lib, sfml-system.lib. etc?
make sure you go into your project properties and go to linker then input, then additional dependencies and link the appropriate files, watch the tutorials on this website to find out which files you need to link
and the difference between SFML 1.6 and SFML 2 is SFMl 2 has a few more features and less bugs
P.S that youtube video does work fine if you have it set up properly i used that one =D.
also i had alot of trouble setting it up but now i know how
