[solved] Error multiple definition of static member of class

[LeslieS]

I would like to have a class member pointer static so that I can access it via classname::pointer.
In the following code titleLabel is a pointer to a QLabel that I would like to make static.
I get an error
:-1: error: mainwindowii.o:(.bss+0x0): multiple definition of `ui::titlelabel'; main.o:(.bss+0x0): first defined here

What am I doing wrong?

#ifndef MAINWINDOWII_H
#define MAINWINDOWII_H

#include <QMainWindow>
#include <QLabel>
#include <QBoxLayout>
#include <QStyle>
#include <QDesktopWidget>
#include <QScreen>


class Game;
//class StateMachine;

namespace Ui {
class MainWindowII;
}

class MainWindowII : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindowII(QWidget *parent = nullptr);
    ~MainWindowII();

    void setGame(Game *g);
    Game *_pGame;                               // pointer to the game object
    static QLabel *titleLabel;                       // label to show the title - probably morph this to use as general purpose image display
    //QLabel *MainWindowII::titleLabel =  new QLabel(); //nullptr_t; // new QLabel(this);

private slots:

    void on_actionNew_Game_triggered();


private:
    Ui::MainWindowII *ui;

    void startNewGame();

    void initTitle();           // load the title bitmap
};

QLabel * titlelabel = new QLabel();

#endif // MAINWINDOWII_H

Move line 45 to the corresponding cpp file.

Doing that removes the multiple def error (thank you)
