下载：

ubuntu-releases-16.04安装包下载_开源镜像站-阿里云 (aliyun.com) http://mirrors.aliyun.com/ubuntu-releases/16.04/

编译环境：



- linux : ubuntu 16.04  内存2G  处理器 2核  缓存5G  硬盘100G


- 虚拟机: VBox


- Android版本：Android4.4

说明：



1. 需要内存要大于1G,我用1G内存编译提示内存分配失败。


2. 在虚拟机上编译，需要增加缓存的大小，我配置的是5G


3. 本文编译的不是Android原生的源码，是全志提供的SDK  针对T-Foucs T3 设备

(一)代码下载

(1)repo下载和安装

Android使用repo管理代码，所以需要在linux上安装repo

1. 根目录下创建.bin文件夹



mkdir ~/.bin


sudo apt-get install curl -y


sudo apt-get install git -y


sudo apt-get install vim -y


curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo


chmod a+x ~/.bin/repo

2. 配置为环境变量



echo 'export PATH=$PATH:$HOME/.bin' > ~/.bashrc

使配置生效



source ~/.bashrc

3. 创建同步源码的工作目录



mkdir ~/.android_source



cd ~/.android_source 


mkdir .repo

5. 可以初始化git代码了

(2)下载代码

代码下载这里只是个示例，需要自己去找自己需要下载版本的链接。



cd android

初始化代码仓：



repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest

同步代码：



repo  sync

(二)安装依赖库



sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib 


sudo apt-get install -y git flex bison gperf build-essential libncurses5-dev:i386 


sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 


sudo apt-get install dpkg-dev libsdl1.2-dev libesd0-dev


sudo apt-get install git-core gnupg flex bison gperf build-essential  


sudo apt-get install zip curl zlib1g-dev gcc-multilib g++-multilib 


sudo apt-get install libc6-dev-i386 


sudo apt-get install lib32ncurses5-dev x11proto-core-dev libx11-dev 


sudo apt-get install libgl1-mesa-dev libxml2-utils xsltproc unzip m4


sudo apt-get install lib32z-dev ccache

(三)安装JDK6.0

Android4.4 依赖的是JDK6.0，不能直接使用命令apt-get install，据说是版权问题，可以自己安装。我使用的是Linux x64 JDK6

可以在下面链接下载Linux x64 JDK6：

链接：https://pan.baidu.com/s/1LaW5twh_90vztSFPKxkspg

提取码：gggb

下载解压后将bin文件拷贝到linux系统下，切换到root权限



# mkdir /usr/java    创建安装路径





# ./jdk-6u45-linux-x64.bin   完成安装

设置环境变量



# vim /etc/profile

在打开的文件末尾添加一下内容：



export JAVA_HOME=/usr/java/jdk1.6.0_45


export JRE_HOME=${JAVA_HOME}/jre


export CLASSPATH=${JAVA_HOME}/lib:${JRE_HOME}/lib


export PATH=${JAVA_HOME}/bin:$PATH

然后保存，关闭文件

设置默认的SDK



sudo update-alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_45/bin/java 300  


sudo update-alternatives --install /usr/bin/javac javac /usr/java/jdk1.6.0_45/bin/javac 300

更新环境变量



# . /etc/profile

查看当前Java版本



# java -version

显示如下内容说明安装成功，可以开始工作喽：



java version "1.6.0_45"


Java(TM) SE Runtime Environment (build 1.6.0_45-b06)


Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

(四)编译Android4.4代码

(1)初始编译环境



source build/envsetup.sh





biao@ubuntu:~/android$ source build/envsetup.sh


including device/asus/tilapia/vendorsetup.sh


including device/asus/flo/vendorsetup.sh


including device/asus/grouper/vendorsetup.sh

(2)选择编译目标

执行lunch命令：



biao@ubuntu:~/android$ lunch

(3)拷贝硬件相关文件

执行命令：extract-bsp



该步骤是在全志平台上有的，其它平台不一定相同。主要进行的是将linux中更硬件平台相关的文件拷贝到Android相应的目录中去。

(4)编译源码



make -j2 && pack

-j2 是多线程编译，跟CPU数有关，最大是CPU数的2倍
