I tryed to write a simple hash programm that just reads a file and
then calculates a tiger hash of it.
While compiling I get the following errors:
1>hash_tiger.obj : error LNK2001: Nicht aufgelöstes externes Symbol

Here is the code of my Programm if it helps:
// hash_tiger.cpp : Definiert den Einstiegspunkt für die
Konsolenanwendung.
//
#include <iostream>
#include <fstream>
#include "stdafx.h"
#include "..\Crypto\tiger.h"
using namespace std;
using namespace CryptoPP;
ifstream::pos_type size;
byte * pbData;
int _tmain(int argc, char *argv[])
{
string filename = "C:\temp.dat";
ifstream dat_ein;
byte abDigest[Tiger::DIGESTSIZE];
/*
if(argc > 1)
filename = argv[1];
else
{
cerr << "Wrong paramter!";
return 1;
}
*/
/* File input */
dat_ein.open(filename.c_str(), ios::in | ios::binary | ios::ate);
//
open file for binary input with pointer at end of file
if(!dat_ein)
{
cerr << "Error with file!";
return 1;
}
size = dat_ein.tellg(); // get the size of the file
pbData = new byte [size]; // allocation of memory
dat_ein.seekg (0, ios::beg); // set pointer to beginning of file
dat_ein.read((char *) &pbData, size); // read whole file at once
dat_ein.close(); // close file
/* Crypto++ */
Tiger thash;
thash.CalculateDigest(abDigest, pbData, size);
cout << "Hash for file = " << abDigest;
return 0;
}
If somebody knows where the error lies, I would be very thankful.
