Template Function under GCC

Question

Duplicate. See this.

Can someone tell me why this does not compile under GCC? Both MSVC6, and VS2008 will compile it, with no warnings, even.

The code...

#include <iostream>
#include <vector>
#include <ctime>
#include <cstdlib>
using namespace std;
template <typename T>
T range(vector<T> &v)
{
   vector<T>::iterator i = v.begin();

Throws an error on the last line, expected ; before i.

Do I need to typedef?

Most of the compiling I do is with MSVC6, or VS2008. I don't do a whole lot with GCC, so I'm a little in the dark.

Answer 1

The compiler does not know enough to parse vector::iterator as a type at that point. Use the typename keyword to give it a hint:

typename vector<T>::iterator i = v.begin();
