Boost meta state machine and Qt

[stereomatching]

I would like to combine Qt meta state machine with Qt
but there are a problem I can't solve

@
#include <boost/msm/back/state_machine.hpp>

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
Ui::MainWindow *ui;
};
@

Will show error messages like

:-1: error: [debug/moc_MainWindow.cpp] Error 1
file not fount

How could I solve this question?Thanks
