Hello @ all,
I am new to Crypto++ and tried to compile my first CPP
project with Visual .NET 2003 - unfortunately i get
"unresolved external" errors. Here is my code:
#include "stdafx.h"
#include <stdlib.h>
#include <stdio.h>
#include "CryptoPP/cryptlib.h"
#include "CryptoPP/des.h"
#include "CryptoPP/modes.h"
//#include "CryptoPP/filters.h"
using namespace CryptoPP;
int _tmain(int argc, _TCHAR* argv[])
{
DES::Encryption des;
return 0;
}
As you can see, i simply tried to initialize a des
object. But even then i get the following errors:
Linking...

I would appreciate any hint on what causes this
unresolved external error,
