Ubuntu-16.04.6 64位开发环境指导

开发前需要在PC安装好Linux操作系统，推荐使⽤Ubuntu 16.04 64bit发行版

安装交叉编译工具链

到网盘下载fsl-imx-xwayland-glibc-x86_64-meta-toolchain-qt5-aarch64-toolchain-4.9.88-2.0.0.sh文件拷贝并解压到你的工作目录下，修改权限、执行脚本

 $ chmod a+x fsl-imx-xwayland-glibc-x86_64-meta-toolchain-qt5-aarch64-toolchain-4.9.88-2.0.0.sh
 $ ./fsl-imx-xwayland-glibc-x86_64-meta-toolchain-qt5-aarch64-toolchain-4.9.88-2.0.0.sh

串口输出如下信息，安装目录默认为/opt/fsl-imx-xwayland，按回车继续安装

NXP i.MX Release Distro SDK installer version 4.9.88-2.0.0
==========================================================
Enter target directory for SDK (default: /opt/fsl-imx-xwayland/4.9.88-2.0.0): 

安装完成后，执行source指令使交叉编译器配置生效，查看交叉编译器版本

 $ source /opt/fsl-imx-xwayland/4.9.88-2.0.0/environment-setup-aarch64-poky-linux
 $ $CC -v

串口输出如下，交叉编译器安装成功
