在centos下编译openwrt 的nodejs ipk时
前面几步：
git clone git://git.openwrt.org/openwrt.git
cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a
都没问题
当执行
make defconfig
出现
Build dependency: Please install a static zlib. (Missing libz.a or zlib.h)
安装zlib-static 即可
yum instal zlib-static
openwrt nodejs ipk编译方法：交叉编译Node.js到OpenWrt（HG255D）
操作系统：deepin linux或ubuntu
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
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。
后记：
HG255D的CPU是Ralink RT3052，mipsel的make
要是启用ssl功能就把“--without-ssl”删掉
如果是ar71xx的u请把里面的mipsel替换成mips
如果是arm的cpu请把替换
LIBS:=-I$(TOOLCHAIN_DIR)/arm-openwrt-linux/include/c++/{gcc版本号}/ -I$(TOOLCHAIN_DIR)/arm-openwrt-linux/include/c++/{gcc版本号}/arm-openwrt-linux-uclibcgnueabi/
和
./configure --dest-cpu=arm --dest-os=linux --without-ssl --without-snapshot --with-arm-float-abi=soft;
以此类推
不管什么版本的openwrt版本里面的node make文件都是出自 https://github.com/giorrrgio/nodejs-linino
（实际上我文章中提到的make文件是出自https://github.com/brimstone/nodejs-openwrt，但是也有参考过nodejs-linino）
mips的建议用attitude adjustment分支编译，不然总出错
mipsel直接用trunk就成了
特别注意：attitude adjustment的gcc版本是4.6.3，而trunk的gcc是4.8.3
