Ubuntu-16.04.6 64位开发环境指导

Linux系统部署

开发前需要在PC安装好Linux操作系统，推荐使Ubuntu 16.04 或者更高版本

可到网盘下载Vmware 14和Ubuntu 16.04镜像文件。

开发环境部署

• 安装一些常用软件为yocto工程做准备，执行如下命令：

 $ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev u-boot-tools

如果是Ubuntu 12.04或14.04，执行如下指令：

 $ sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff curl lzop asciidoc

• 将软件源替换成清华源

清华源网址：https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/ 选择16.04 ，然后把内容更新到 /etc/apt/source.list 文件中。

备份源

 $ sudo cp /etc/apt/sources.list /etc/apt/sources.list-bak

复制16.04清华源内容到此/etc/apt/sources.list 文件，更新源

 $ sudo apt-get update

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
