Hello i am refrencing Chapter 3 in the book Sfml Game Development.. ive been doing well until now. i cant get this to work i even copied and pasted all the git hub stuff to replace what i wrote and i still get the same errors..
https://github.com/SFML/SFML-Game-Development-Book/tree/master/03_World is the source i copy and pasted and still no work. my error messages are:
