QtCore/QTime: No such a file or directory

[Isaac]

Hi I'm trying to compile a code wich start with this lines:

#include <stdio.h>

// Qt stuff

#include <QtCore/QTime>

#include <QtCore/QTimer>

#include <QtGui/QApplication>

#include <QtGui/QGraphicsRectItem>

#include <QtGui/QPen>

#include <QtGui/QColor>

// OpenCV stuff

#include <opencv2/core/core.hpp>

#include <opencv2/highgui/highgui.hpp>

#include <opencv2/features2d/features2d.hpp>

#include <opencv2/nonfree/features2d.hpp>

#include <opencv2/calib3d/calib3d.hpp> // for homography

when I compile I got this:

QtCore/QTime: no such a file or directory 

I checked out and I have installed the libqt4-dev library, I don't know what else I need to install. 

Please some help. Thanks in advance.
