安装所需工具
sudo apt install build-essential libncurses5-dev zlib1g-dev
sudo apt install gawk gcc-multilib flex git gettext libssl-dev
sudo apt install python3-distutils

./scripts/feeds update -a
./scripts/feeds install -a

配置所需的模块 Target image选 iso（virtualbox 的vdi会报错）
make menuconfig

#编译：显示编译信息，-j2 使用2核编译
make V=s -j2

生成镜像的目录 openwrt-21.02.3/bin/targets/x86/64

应用helloword 编写
生成的ipk目录 openwrt-21.02.3/bin/packages/x86_64/base
