I am new to GUI's, and I heard that SFML would be a great starter. After a while of struggling to link the libraries (not the problem), I finally got it to work. But I get every error with every sample code I use:
That's quite an outdated tutorial. I suggest you use SFML 2.0 at this stage. You will have to build it from the source yourself, but don't worry as it's not as hard as you might think and certainly a good learning experience.
