Android源码下载与编译过程记录

参考:http://www.linuxidc.com/Linux/2016-08/134274.htm

Android 6.0百度网盘下载  http://www.linuxidc.com/Linux/2016-01/127285.htm

1、Android源码下载

参考了以下的下载失败重下载脚本:

[linuxidc@localhost android-src]$ cat myrepo.sh
#!/bin/sh
repo sync
while [ $? -ne 0 ]
do
    echo “try repo sync again”
    repo sync
done
[linuxidc@localhost android-src]$

下班前开始跑,第二天就有了。

2、编译第一次直接进入下载的源代码目录,运行make,过了3个多小时后,报错:

//—2015-11-13–//

make之前还运行了下面的指令:

#source ./build/envsetup.sh

这个命令选择你的编译环境的硬件体系

#lunch

下面这个命令就开始编译了

#make

通过跟踪顶层makefile,找到有关jack的目录:prebuilts/sdk/tools,其中看到有个jack-admin,正是启动jack所在的shell。里面有个设置:

#
# Settings
#
JACK_HOME=”${JACK_HOME:=$HOME/.jack-server}”
CLIENT_SETTING=”${CLIENT_SETTING:=$HOME/.jack-settings}”
TMPDIR=${TMPDIR:=/tmp}
JACK_SERVER_VM_ARGUMENTS=”${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation}”

修改一下,增加-Xmx2048M:

#
# Settings
#
JACK_SERVER_VM_ARGUMENTS=”${JACK_SERVER_VM_ARGUMENTS:=-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx:2048M}”

再次make,好像没起作用:

[  1% 296/20841] Build: out/host/linux…bj/EXECUTABLES/jack_intermediates/jack
Jack server already installed in “/home/gumh/.jack-server”
Launching Jack server java -Djava.io.tmpdir=/tmp -Dfile.encoding=UTF-8 -XX:+TieredCompilation -cp /home/gumh/.jack-server/launcher.jar com.android.jack.launcher.ServerLauncher

找到jack-admin中的start-server语句,直接在里面增加:

 start-server)
    isServerRunning
    RUNNING=$?
    if [ “$RUNNING” = 0 ]; then
      echo “Server is already running”
    else
      echo “before to start-server,JACK_SERVER_VM_ARGUMENTS=” $JACK_SERVER_VM_ARGUMENTS
      JACK_SERVER_COMMAND=”java -Djava.io.tmpdir=$TMPDIR $JACK_SERVER_VM_ARGUMENTS-Xmx2048M -cp $LAUNCHER_JAR $LAUNCHER_NAME”
      echo “Launching Jack server” $JACK_SERVER_COMMAND
      (

再次执行make指令,这次ok了。

这里有一个问题没弄清楚:有时候执行make的时候,会自动启动jackserver,有时候又不会,会报错说server未启动,请用jack-admin start-server来启动的提示。

经过了4个多小时,终于完成了。

这些应该如何测试呢?下面再补。
