I am trying to compile a program using md5 and I had some problems. So I made 
a test program to see if I was using it properly, and it still doesn't work. 
The test  program is:

#include <iostream>
#include <sys/types.h>
#include <md5.h>

#define MAX_STR 100

using namespace std;
typedef unsigned short int usi;

int main()
{
	unsigned char Str[MAX_STR];
	cout << "Enter a string to md5:" << endl;
	cin.getline(Str, MAX_STR);

	char Result[33];
	MD5Data(Str, MAX_STR, Result);
	cout << Result << endl;

	return 0;
}

The problem is it won't compile giving:
[ian@hercules:~/devel] %g++ md5.cpp -o md5
/tmp/cc8WdTS0.o: In function `main':
/tmp/cc8WdTS0.o(.text+0x57): undefined reference to `MD5Data'

It looks like I am missing a .o file or something. I am reasonably new to C++ 
so any kind of help will be much appreciated.
