- 下載 QT Demo 原始碼包 在網盤“2.3_系統_Linux-4.1.15/05_MY-Demo”中下載 myzr-qt5-demo.tar 並複製到編譯主機中。
- 解壓 QT Demo 原始碼包
$ tar xf myzr-qt5-demo.tar
- 進入 QT Demo 工程目錄
$ cd myzr-qt5-demo/AboutUs
- 為工程生成 Makefile
$ qmake 編譯工程

執行目標程式
1.把編譯生成的 AboutUs 複製到評估板上。 2.執行目標程式

$ ./AboutUs -platform eglfs -plugin evdevtouch:/dev/input/event0 QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync. If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1 Unable to query physical screen size, defaulting to 100 dpi. To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
