Hello Corey:
When I put the 'using std::hash;' line in the .h file,
I get an additional error that says
'hash' not declared (as shown below). The line number
corresponds to the new line.
On moving the 'using std::hash' line to the .cc file,
the error is exactly as before (only the above
mentioned error is missing).
I read in a couple of postings that such declarations
ought to be made in the .cc file.

In my .h file:
#include <ext/stl_hash_fun.h>
#include <ext/hash_map>
using std::hash;
class HTEntry {
public:
double time;
double ttl;
};
typedef hash_map<int, pair<int,HTEntry>, hash<int>,
equal_to<int> > HMap;
class Hash_Table
{
public:
void increment(int, double, double);
int lookup(int,double,double);
int findsize(double,bool);
int estimate_hit(double);
protected:
HMap flows;
};
In the .cc file:
#include <iostream>
#include <sstream>
#include <cmath>
#include <valarray>
#include <string>
#include <sys/types.h>
#include "config.h"
#include "template.h"
#include "flags.h"
#include "delay.h"
#include "rd.h"
using namespace std;
void Hash_Table::increment(int id, double t_now,
double ttl)
{
HMap::iterator iter;
iter=flows.find(id);
double timelived, thresh;
int hits;
// bunch of stuff
}
//other functions that I leave out.

Similar errors for other functions removed for
simplicity.
Any help is appreciated.
