安装 SDK下载 SDK

　　在网盘“2.3_系统_Linux-4.1.15/03_工具”目录中下载 SDK 包文件。

• MY-IMX6-EK140、MY-IMX-EK40P：
  

　　fsl-imx-fb-glibc-x86_64-meta-toolchain-qt5-cortexa7hf-neon-toolchain-4.1.15-2.1.0.sh

• MY-IMX6-EK200、MY-IMX-EK314、MY-IMX-EK336：
  

　　fsl-imx-fb-glibc-x86_64-meta-toolchain-qt5-cortexa9hf-neon-toolchain-4.1.15-2.1.0.sh

准备安装

• 把下载的包文件复制到编译主机中。
• 修改预安装目录的权限
  

$ chmod 777 /opt -R SDK 安装（MY-IMX6-EK140、MY-IMX-EK40P）

• 安装 SDK 包文件

编译 QT 应用程序配置交叉编译工具环境变量

• MY-IMX6-EK140、MY-IMX-EK40P
  

$ source /opt/fsl-imx-fb/4.1.15-2.1.0/environment-setup-cortexa7hf-neon-poky-linux-gnueabi

• MY-IMX6-EK200、MY-IMX-EK314、MY-IMX-EK336
  

$ source /opt/fsl-imx-fb/4.1.15-2.1.0/environment-setup-cortexa9hf-neon-poky-linux-gnueabi 准备编译工程

• 下载 QT Demo 源码包
  在网盘“2.3_系统_Linux-4.1.15/05_MY-Demo”中下载 myzr-qt5-demo.tar 并复制到编译主机中。
• 解压 QT Demo 源码包
  

$ tar xf myzr-qt5-demo.tar

• 进入 QT Demo 工程目录
  

$ cd myzr-qt5-demo/AboutUs

• 为工程生成 Makefile
  

$ qmake 编译工程

• MY-IMX6-EK140、MY-IMX-EK40P

• 查看编译生成的目标文件
  

$ file AboutUs AboutUs: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=38367b0a95b8fe7402e2377c11626581c07f9c9d, not stripped
运行目标程序

1.把编译生成的 AboutUs 复制到评估板上。

2.运行目标程序

• MY-IMX6-EK200、MY-IMX-EK314、MY-IMX-EK336
  

$ ./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).
