Newbie problem with QT C++ - Qimage dont work?

Question

I am trying to do console application to read pixels from image:

#include <QtCore/QCoreApplication>
#include <QtGui/QImage>

#include <iostream>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QImage *img = new QImage("adadad.jpg");

    //std::cout << "Type filename:" << std::endl;
    img->isNull();
    return a.exec();
}

That doesn't work I got: (IT doesn't compile, but anyway file isn't exist yet...)

File not found: tmp/obj/debug_shared/main.o:: In function `main':

What is going on? Is it impossible to use Qimage with console app?!

EDIT: screen

Solution

It is possible to use QImage in a console application, you must make sure that QtGui is configured though. If you chose a console app, your .pro file might contain something like

CONFIG += console
QT -= gui

If that's the case, remove the QT -= gui line.
