iterator

[Douglas Dude]

template<typename T>
void foo(std::map<std::string, T>&m){
std::map<std::string, T>::iterator it=m.begin();
//do something
}

That would fail on g++ at "it"
Is there another way around to use iterator with unknown T ? Thanks

template<typename T>
void foo(std::map<std::string, T>&m){
std::map<std::string, T>::iterator it=m.begin();

//do something
}

Best

It's always best to paste the error message into the posting.

Try:

typename std::map<std::string, T>::iterator it=m.begin();
