Hi everybody,
This is driving me up the wall, I cannot get this thing to run and I've tried everything, I'm trying to follow the book example from
http://www.amazon.com/SFML-Game-Development-Jan-Haller/dp/1849696845 Chapter 1 and I'm getting an error at compile
**EDIT**
If I remove the call to loadFromFile it seems fine, although it does nothing....
**ENDEDIT**
**EDIT**
Oh and I'm using VS2013 community ed, but I've also tried this on VC++E2010 too and I get the same issue
**ENDEDIT**
