Yocto:嵌入式Linux开发快速入门

Yocto是一个快速构建嵌入式Linux的编译组件，类似于Buildroot。它是Linux基金会主导的一个开源项目。

安装环境
在Windows 10/11上通过VMware Workstation安装Ubuntu 24.04，安装完Ubuntu 24.04，在命令行下行安装编译套件
$ sudo apt install build-essential chrpath \
   cpio debianutils diffstat file gawk gcc \
   git iputils-ping libacl1 liblz4-tool locales \
   python3 python3-git python3-jinja2 \
   python3-pexpect python3-pip \
   python3-subunit socat texinfo unzip wget \
   xz-utils zstd
获取源码
在当前目录下创建目录yocto-5.0.16
$ mkdir yocto-5.0.16
获取yocto源码仓库到yocto-5.0.16下
$ git clone -b scarthgap --single-branch \
   git://git.yoctoproject.org/poky yocto-5.0.16
设置环境
切换目录至yocto-5.0.16/poky
$ cd yocto-5.0.16/poky
开始编译之前，设置编译环境
$ source oe-init-build-env
开始编译
$ bitbake core-image-sato
