① 安装编译依赖
sudo apt update -y
sudo apt full-upgrade -y
sudo apt install -y ack antlr3 asciidoc autoconf automake autopoint binutils bison build-essential \
bzip2 ccache clang cmake cpio curl device-tree-compiler flex gawk gcc-multilib g++-multilib gettext \
genisoimage git gperf haveged help2man intltool libc6-dev-i386 libelf-dev libfuse-dev libglib2.0-dev \
libgmp3-dev libltdl-dev libmpc-dev libmpfr-dev libncurses5-dev libncursesw5-dev libpython3-dev \
libreadline-dev libssl-dev libtool llvm lrzsz libnsl-dev ninja-build p7zip p7zip-full patch pkgconf \
python3 python3-pyelftools python3-setuptools qemu-utils rsync scons squashfs-tools subversion \

② 下载源代码，更新 feeds 并选择配置
git clone https://github.com/coolsnowwolf/lede
cd lede
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig
③ 下载 dl 库，编译固件
make download -j8
make V=s -j1
④ 二次编译
cd lede
git pull
./scripts/feeds update -a
./scripts/feeds install -a
make defconfig
make download -j8
make V=s -j$(nproc)
