操作系统：Deepin Linux 2013 或 Ubuntu 13.04
1、安装交叉编译前，需要安装的包
sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt xsltproc
2、下载OpenWrt的源代码
git clone git://git.openwrt.org/openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
make defconfig
make prereq
make menuconfig
按照下图选择对应的项目
3.关键的一步
cd package
mkdir node
sudo gedit Makefile

define Package/node/description
Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

4.保存配置文件后编译： make V=99 （参数为输出调试信息）
5.把openwrt/bin/ramips/packages下的
node_v0.10.28-2_ramips_24kec.ipk
uclibcxx_0.2.4-1_ramips_24kec.ipk
懒得自己编译的同学，可以到我的网盘下载
拷贝到路由器，先安装uclibcxx_0.2.4-1_ramips_24kec.ipk库，再安装node_v0.10.28-2_ramips_24kec.ipk，安装node的时候要耐心等待，我第一次安装的时候等了一会没有响应，以为编译失败了，终止了安装进程，因此而耗费了很多时间。
