安装依赖软件包

brew install make grep asciidoc docbook gdbm libxml2 pbzip2 autoconf e2fsprogs gettext libxslt pkg-config bash-completion fastjar gnu-getopt libyaml readline binutils findutils gnu-tar lzlib sqlite bison flex gputils openssl wget coreutils gawk intltool ossp-uuid xz

手动为 getopt 建立一个链接

cd /usr/local/bin 
ln -s ../Cellar/gnu-getopt/版本号/bin/getopt .

使用磁盘工具添加一个区分大小写的宗卷

克隆源码并整合lean²

切换到区分大小写的宗卷下，克隆openwrt与lean的源码

git clone https://github.com/project-openwrt/lean-lede.git
git clone https://github.com/openwrt/openwrt.git

将lede的软件包拷贝到openwrt目录下

cp -a ./lean-lede/package/lean ./openwrt/package/lean

切换luci版本并修改最大连接数、添加其他软件包

cd ./openwrt
cp feeds.conf.default feeds.conf.default.bak
sed -i "" 's/https:\/\/git.openwrt.org\/project\/luci.git/https:\/\/github.com\/coolsnowwolf\/luci/g' feeds.conf.default
sed -i "" 's/16384/65536/g' ./package/kernel/linux/files/sysctl-nf-conntrack.conf
cd ./package/lean
git clone https://github.com/fumiama/luci-app-ssr-plus.git
cd ../../../
git clone https://github.com/fumiama/luci-theme-rosy.git
cp -a ./luci-theme-rosy/luci-theme-rosy ./openwrt/package/lean/

更新、安装feeds并进行菜单配置
注意： 由于未使用lean的所有内容，因此有些软件包可能会出现兼容性问题，需要手动调试修复，或直接取消编译此软件包

cd ./openwrt
./scripts/feeds update -a
./scripts/feeds install -a
gmake menuconfig

修复软件包权限/内容

修复vlan
此版本的luci会在打开交换机界面时会报错。获得报错信息后，做相应修改即可

/usr/lib/lua/luci/dispatcher.lua:381: Failed to execute cbi dispatcher target for entry '/admin/network/vlan'.
The called action terminated with an exception:
/usr/lib/lua/luci/model/cbi/admin_network/vlan.lua:140: bad argument #2 to 'tonumber' (integer expected, got string)
stack traceback:
	[C]: in function 'assert'
	/usr/lib/lua/luci/dispatcher.lua:381: in function 'dispatch'
	/usr/lib/lua/luci/dispatcher.lua:95: in function </usr/lib/lua/luci/dispatcher.lua:94>

由报错信息可知，错误发生于/usr/lib/lua/luci/model/cbi/admin_network/vlan.lua，对应源代码目录经查询可知有6处。未开始编译时会更少，编译后不需要修改feeds文件夹中内容。
vlan
具体修改方法是，在m:get函数外多加一层括号。

return(tonumber((m:get(e[t],a or"vlan")))or 9999)
<(tonumber((m:get(e[o],a or"vlan")))or 9999)

修复文件权限

cd ./package/lean
chmod 755 luci-app-ssr-plus/root/etc/init.d/shadowsocksr
chmod 755 luci-app-ssr-plus/root/etc/uci-defaults/luci-ssr-plus
chmod 755 luci-app-ssr-plus/root/usr/bin/*
chmod 755 luci-app-ssr-plus/root/usr/share/shadowsocksr/*.sh
chmod 644 luci-theme-rosy/luasrc/view/themes/rosy/footer.htm
cd ../base-files
chmod 755 files/etc/uci-defaults/*
chmod -R 755 files/lib/

开始编译³

下载+编译+纠错大约需要一天时间，请耐心等待

cd ../../
gmake -j8 download V=s	#下载速度较慢，请尽量全程科学上网
gmake -j1 V=s			#首次编译务必使用j1，否则会报错
