编译预先准备
1、Debian编译环境准备
必须使用非root账户完成如下操作
所有操作务必在翻墙后执行
以lean版本Lede为例
需要大概20G空间编译
sudo apt-get -y install build-essential asciidoc binutils bzip2 gawk gettext git libncurses5-dev libz-dev patch unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex uglifyjs git-core gcc-multilib p7zip p7zip-full msmtp libssl-dev texinfo libglib2.0-dev xmlto qemu-utils upx libelf-dev autoconf automake libtool autopoint
安装完成后环境即准备完毕。
git clone https://github.com/coolsnowwolf/lede
Openwrt源代码准备完毕
2、选择编译对象
cd lede
./scripts/feeds update -a
./scripts/feeds install -a
会自动克隆最新版的OpenWrt官方源码，由于源码速度不理想，所以最好全局翻墙保证速度和完整性，大部分克隆失败，编译失败都是没有访问到源码repo的问题。
如果你想自行添加软件包，可以在lede/feeds/packages目录当中用普通用户添加软件包，然后再执行上述命令更新软件包，同样修改软件包也需要在对应的目录当中修改对应的内容。
例如我会手动去更新源码当中的udpxy版本，只需要修改对应的Makefile即可，可以参考文章《 Openwrt编译udpxy流程和相关设置解析》。
make menuconfig
需要注意的是，默认的Openwrt不会包含太多的软件包，可能编译出来会缺失一些自己喜欢的功能，下面列出一些常用软件包的目录和解释，来自于山恩论坛

3、开始编译
make -j1 V=s
首次编译会编译全部软件包，约2小时，后续编译会仅仅编译重新配置的部分，时间较短，所以尽量在screen当中编译，防止意外ssh掉线。
最终编译出来的软件包在这里
./lede/bin/targets/x86/64/openwrt-x86-64-combined-squashfs.img
4、安装OpenWrt
编译完成后的img文件可以在linux当中通过dd去安装到磁盘，首次安装后后续可以通过OP自带的升级功能来进行升级即可
dd if=/dev/sda of=xxx.img bs=1M
