undefined reference to class constructor



      I am getting undefined to a class constructor... here is my code. Can you plese tell me the solution..


#include "App.hpp"
#include "AdvertisementScreen.hpp"

#include <bb/cascades/Application>
#include <bb/cascades/QmlDocument>
#include <bb/cascades/NavigationPane>

using namespace bb::cascades;
App::App(bb::cascades::Application *app) : QObject(app) 
	// create scene document from main.qml asset
	// set parent to created document to ensure it exists for the whole application lifetime
	QmlDocument *qml = QmlDocument::create("asset:///page/Main.qml").parent(this);

	obj_advertisement_screen = new AdvertisementScreen();// here it is showing undefined reference
                                                                            // to  AdvertisementScreen::AdvertisementScreen()
	// create root object for the UI
	NavigationPane *root = qml->createRootObject<NavigationPane>();
	// set created root object as a scene
