Issues with declaring vector iterator

[lancevo3]

Hey guys I am having issue with declaring an iterator of type vector. I know there are other errors within this file but I am more concerned with why these declarations arent working. Everyone gives me an error saying something along these lines for each iterator
heapsort.h:45: error: expected `;' before âitrâ

#include <iostream>
#include <string>
#include <vector>
#include <fstream>

using namespace std;

template <class T>
void build_list(vector<T>&, const char*);

template <class T>
void print_list(const vector<T>&, int, int);

template <class T>
void sort_list(vector<T>&, Pred);

template <class T>
void build_list(vector<T>& itemList, const char* fileName)
{
	ifstream inFile;
	inFile.open(fileName);

	if(inFile.fail())
		{
		cout << "input file did not open";
		exit(0);
		}

	string item;
	int i = 0;

	while(inFile >> item)
	{
		itemList[i] = item;
		i++;
	}

	inFile.close();
}	

template <class T>
void print_list(const vector<T>& itemList, int itemWidth, int numPerLine)
{
	vector<T>::const_iterator itr;
	int x = 0;

	for(itr = itemList.begin(); itr != itemList.end(); ++itr)
		{
		if(x <= numPerLine)
			cout << left << setw(itemWidth) << *itr;
		else
			cout << endl << left << setw(itemWidth) << *itr;
		x++;
		}
}
template <class T, class Pred>
void sort_list(vector<T>& itemList, Pred predicate)
{
	vector<T>::iterator itrStart;
	vector<T>::iterator itrEnd;

	priority_queue pq(itrStart, itrEnd, predicate);
}
