Most likely because the compiler doesn't think that it's compiling an 
objective-c++ file, which means that it isn't using the C++ header 
search paths. What extension are you using for your filename? You have 
to use .mm to tell the compiler that it's objective-c++.

It should be a .mm file.

#ifdef __OBJC__
//objc only stuff
#endif
