about console application

Hi all, I have create a simple hello world application in Qt Console application. I use Qt 4.4.3 with eclipse integration plug-in. When I build and run in eclipse it work fine, the Hello World message show up. But when I using command prompt(cmd) then go to the debug folder and call the program directly nothing happen!

Does anyone know why?

by the way here is the code

Code:

---

#include <iostream>
#include <QtCore>
#include <QCoreApplication>
 
using namespace std;
 
int main(int argc, char *argv[])
{
    cout << "Hello World\n";
 
    return 0;
}

it may be that the neccessary libraries are not included using the comamnd prompt. (pretty old post, but maybe still a question for some, hopefully myou have already found the answer)
