iterator for vector of pointers to generic type won't compile

[Mike Gashler]

This function iterates over a vector to find an element. It won't compile with g++ 4.2.4

#include <vector>
template<typename T>
size_t index_of(vector<T*>& v, T* p)
{
 for(std::vector<T*>::iterator it = v.begin(); it != v.end(); it++)
  if(p == *it)
   return (it - v.begin());
 return -1;
}

The error is:

    error: expected `;' before ‘it’

Visual C++ 2005 can compile this code. I know that doesn't always mean much, but in this case I think they are correct. If I am mistaken such that this code really should not compile, the issue is definitely not a missing semicolon before 'it', so at least the error message could be improved a bit.

My mistake. Sorry. The solution is to change this line
 for(vector<T*>::iterator it = v.begin(); it != v.end(); it++)
to
 for(typename vector<T*>::iterator it = v.begin(); it != v.end(); it++)
