Question

我正在编写简单的2D游戏，我必须在qt中做一些事情。游戏运行良好，它是在2015年写的，现在我把它移到了qt创建者。

有opengl小部件来显示图形。我在.pro文件中添加了东西，我可以使用opengl函数，除了gluLookAt（用于计时器函数cscenaqt），我得到错误：

    cscenaqt.obj:-1: błąd: LNK2019: unresolved external symbol gluLookAt referenced in function "protected: virtual void __cdecl cScenaQt::timerEvent(class QTimerEvent *)" (?timerEvent@cScenaQt@@MEAAXPEAVQTimerEvent@@@Z)

这是opengl小部件文件

#ifndef CSCENAQT_H
#define CSCENAQT_H

#include <QWidget>
#include <QGLWidget>

class cScenaQt : public QGLWidget
{
    Q_OBJECT        // must include this if you use Qt signals/slots

public:
    cScenaQt(QWidget *parent);

protected:

    void initializeGL();

    void resizeGL(int w, int h);

    void paintGL();
    void mouseMoveEvent(QMouseEvent * event);
    void keyPressEvent(QKeyEvent* e);

    void timerEvent(QTimerEvent *event);
private:
    float m_x,m_y;
    int m_timer_id;
};

#endif // CSCENAQT_H

这是.pro文件

我如何解决这个问题并且有一些方法允许用户在qt中使用多个密钥（我知道在opengl中可以使用glkeyupfun和keydown，像这样的smth）？

qt + opengl gluLookAt问题
