Node.js在物联网

1、Build Node.js for Android

Linux构建环境

jiangling@young:~/node/deps/npm$ uname -a
Linux young 3.11.0-15-generic #25~precise1-Ubuntu SMP Thu Jan 30 17:39:31 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

32位 Android NDK

clone node.js

git clone https://github.com/joyent/node.git

android-configure patch

jiangling@young:~/node$ git diff
diff --git a/android-configure b/android-configure

否则会出现arm-linux-androideabi-gcc not found的错误。

configure && make

source ./android-configure ~/android-ndk-r9b
mv python2.7 oldpython2.7
ln -s /usr/bin/python2.7 python2.7
cd  ~/node
make

node bin大小

jiangling@young:~/node$ file out/Release/node 
out/Release/node: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

root@android:/data/local/tmp # ls -al node
ls -al node
-rwx------ shell    shell    12158228 2014-11-24 17:01 node

配置without-ssl后大小

jiangling@young:~/node$ ls -al out/Release/node 
-rwxrwxr-x 1 jiangling jiangling 9804644 11月 26 13:55 out/Release/node

2、Run Node.js on Android

这边我选择了ROOT过的小米M1手机， 安装了”瑞士军刀“busybox, 以便查看系统信息。

root@android:/data/local/tmp # ./busybox uname -a
./busybox uname -a
Linux localhost 3.4.0-perf-g1ccebb5-00146-gd6845ec #1 SMP PREEMPT Mon Nov 4 20:10:00 CST 2013 armv7l GNU/Linux

用ADB将 node, test.js(经典的hello world) push到M1上：

adb push d:\node /data/local/tmp
adb push d:\test.js /data/local/tmp
adb shell chmod 755 /data/local/tmp/node

运行 和 结果
