Output to terminal

[wookie1]

Hi I'm brand new to Qt, hence the forum, and having troubles running a tester hello world program.
I used create project - console project.

#include <QtCore/QCoreApplication>
#include <QDebug>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    qDebug() << "Hello World";
 
    return a.exec();
}

#include <QtCore/QCoreApplication>
#include <QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    qDebug() << "Hello World";
    
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

This builds ok and runs with no errors but the terminal doesn't output any text.
When I tried not outputting to console it outputted into the application output window fine.
I'm not sure what to check next, any help is much appreciated.
I'm on UBUNTU 12.04
