So, today I wanted to do something I have never done before, and that is sound. So I decided to use SDL_mixer, as I've heard it is quite simple.
But I still can't get it to compile. The problems seems to be that I have an independent function called void SetUp(). Ok, so I was naive enough to make a method in CSoundManager with the same name. And therefore it is saying that it "can't override CSoundManager::SetUp()" even though I've changed it to "CSoundManager::Ready()" a few tries ago.

Soooooo, any ideas? I've tried "Rebuild all" and "Compile current file" but to no avail.

Sorry for not giving you a more juicy update, I'am really sorry [sad].
