• (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-addr2line  arm-linux-androideabi-gcc         arm-linux-androideabi-ld       arm-linux-androideabi-size
    arm-linux-androideabi-ar         arm-linux-androideabi-gcc-4.9     arm-linux-androideabi-ld.bfd   arm-linux-androideabi-strings
    arm-linux-androideabi-as         arm-linux-androideabi-gcc-ar      arm-linux-androideabi-ld.gold  arm-linux-androideabi-strip
    arm-linux-androideabi-c++        arm-linux-androideabi-gcc-nm      arm-linux-androideabi-ld.mcld  python
    arm-linux-androideabi-c++filt    arm-linux-androideabi-gcc-ranlib  arm-linux-androideabi-nm       python2
    arm-linux-androideabi-cpp        arm-linux-androideabi-gcov        arm-linux-androideabi-objcopy  python2.7
    arm-linux-androideabi-dwp        arm-linux-androideabi-gcov-tool   arm-linux-androideabi-objdump
    arm-linux-androideabi-elfedit    arm-linux-androideabi-gdb         arm-linux-androideabi-ranlib
    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 ");
    });

    // 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.
