(OK) 交叉编译node-v4.2.1—for—android


参考:http://www.goland.org/nodejsonandroid/


第1步:下载node-v4.2.1

[root@localhost node-v4.2.1]# wget -c https://nodejs.org/download/release/latest/node-v4.2.1-linux-armv7l.tar.gz
[root@localhost node-v4.2.1]# pwd
/opt/cBPM-android/node-v4.2.1

第2步:查看、编辑 android-configure文件内容

[root@localhost node-v4.2.1]# gedit android-configure
------------------------------------------------------------------------------下面是android-configure文件内容
#!/bin/bash

export TOOLCHAIN=$PWD/android-toolchain
mkdir -p $TOOLCHAIN
$1/build/tools/make-standalone-toolchain.sh \
    --toolchain=arm-linux-androideabi-4.9 \
    --arch=arm \
    --install-dir=$TOOLCHAIN \
    --platform=android-14
export PATH=$TOOLCHAIN/bin:$PATH
export AR=$TOOLCHAIN/bin/arm-linux-androideabi-ar
export CC=$TOOLCHAIN/bin/arm-linux-androideabi-gcc
export CXX=$TOOLCHAIN/bin/arm-linux-androideabi-g++
export LINK=$TOOLCHAIN/bin/arm-linux-androideabi-g++

./configure \
    --dest-cpu=arm \
    --dest-os=android
------------------------------------------------------------------------------

第3步:Run from inside of node directory the command

[root@localhost node-v4.2.1]# . android-configure /opt/android-on-linux/android-ndk-r10d

第4步:mv python2.7 oldpython2.7 && ln -s /usr/bin/python2.7 python2.7

[root@localhost node-v4.2.1]# cd android-toolchain/bin/
[root@localhost bin]# pwd
/opt/cBPM-android/node-v4.2.1/android-toolchain/bin
[root@localhost bin]# ls

arm-linux-androideabi-g++        arm-linux-androideabi-gprof       arm-linux-androideabi-readelf
[root@localhost bin]# mv python2.7 oldpython2.7
[root@localhost bin]# ln -s /usr/bin/python2.7 python2.7
[root@localhost bin]#

[root@localhost node-v4.2.1]# cd android-toolchain/bin/; mv python2.7 oldpython2.7; ln -s /usr/bin/python2.7 python2.7; cd -

第5步:编译node

[root@localhost node-v4.2.1]# make -j5

注意:编译时,如果遇到大量的 类型 定义 冲突错误,很可能是版本的问题:android-ndk-(r8e, r9d, r10d)、platforms/android-(14, 19, 21, ...)

-----------------------------------------------------------------编译时,出现问题如下
error: undefined reference to 'getpwuid_r'

解决方法(使用getpwuid替换getpwuid_r):
[root@localhost node-v4.2.1]# grep getpwuid_r -R .
[root@localhost node-v4.2.1]# gedit ./deps/uv/src/unix/core.c

    //r = getpwuid_r(uid, &pw, buf, bufsize, &result);
替换为:
    //r = getpwuid_r(uid, &pw, buf, bufsize, &result);
    result = getpwuid(uid);  
    if(result == NULL) r = 0;

-----------------------------------------------------------------至此,编译成功,下面测试
//宿主机
[root@localhost ~]# adb root
[root@localhost ~]# adb shell
//手机
root@mb526:/ # mkdir -p /data/data/node/Release
root@mb526:/ #

//宿主机
[root@localhost node-v4.2.1]# pwd
/opt/cBPM-android/node-v4.2.1
[root@localhost node-v4.2.1]# du -hs out/Release/
100M    out/Release/
[root@localhost node-v4.2.1]# adb push out/Release/ /data/data/node/Release    //将node复制到手机

//手机
root@mb526:/ # cd /data/data/node/Release
root@mb526:/ # chmod 700 node

//宿主机
[root@localhost node-v4.2.1]# gedit out/Release/helloworld.js        //内容如下(红色):
//-------------------------------------
// Load the http module to create an http server.
var http = require('http');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.end("Hello World\n");
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

// Put a friendly message on the terminal
console.log("Server running at http://127.0.0.1:8000/");
//-------------------------------------(更多例子:http://howtonode.org/hello-node)
//宿主机
[root@localhost node-v4.2.1]# adb push out/Release/helloworld.js /data/data/node/Release

//手机
root@mb526:/data/data/node/Release # ./node helloworld.js

//宿主机,浏览器,成功访问
http://192.168.0.101:8000/


至此,OK


-----------------------------------------------------------------编译时,可能出现问题 如下
在安装node.js时提示ImportError: No module named bz2。
这个python中没有装bz2的库导致的。
解决方法:
yum install bzip2-devel
---------------------------
error: undefined reference to 'getpwuid_r'
出现这个错误是因为我使用了 --platform=android-14 , 修改为 --platform=android-21
Answer 1:The API level in our build script was recently raised to 21, closing. If you need support for an API level < 21, a patch would be welcome

Answer 2:There is no getpwuid_r implementation in bionic libc in Android platforms below 19. Just remove the call off the code.
