help with templates please

QMap<T,QString>::iterator it;

QMap<T,QString>::iterator it;

To copy to clipboard, switch view to plain text mode 

Because compiler does not know that "iterator" is a typename. You need to specify that:

typename QMap<T,QString>::iterator it;

typename QMap<T,QString>::iterator it;

To copy to clipboard, switch view to plain text mode

I see that g++ (v 4.5.2) produces a nice message:

template <class C> class Test{
	public:
		void fun();
};
 
template<class C> void Test<C>::fun(){
	C::iterator it;
}
 
// error: need 'typename' before 'C:: iterator' because 'C' is a dependent scope

template <class C> class Test{
	public:
		void fun();
};

template<class C> void Test<C>::fun(){
	C::iterator it;
}

// error: need 'typename' before 'C:: iterator' because 'C' is a dependent scope
