编译android源码

首先搭建android编译环境。

（一）安装配置java5

1 先安装java6(编译android需要java5，此处为推荐)

打开终端，执行以下命令，或使用Adept/新立得软件管理器，在其中分别搜索"sun-java6-jre"和"sun-java6-jdk"并标记安装。

sudo apt-get install sun-java6-jre

如果空间富裕，建议安装一个JDK。

sudo apt-get install sun-java6-jdk

提示：安装过程中需要你回答是否同意使用协议（终端中红蓝色的提示界面），此时按tab键至OK，再按回车即可正常安装。

2 安装java5

　　　　　　如果是ubuntu910版本，安装java5时需要更新源，方法：

　　 将下面更新放到更新源最前面

更新的源：sudo gedit /etc/apt/sources.list

　　　　　　deb http://cn.archive.ubuntu.com/ubuntu/ jaunty multiverse

　　　　　　deb http://cn.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse

　　　　　sudo apt-get install sun-java5-jre

　　　　 sudo apt-get install sun-java5-jdk

3 设置当前默认的java解释器和编译器： (ubuntu9.10如果没有安装多个java虚拟机的话可以跳过这一步。)

sudo update-alternatives --config java

执行后会出现类似如下的画面:

There are 2 alternatives which provide `java'.

Selection Alternative

-----------------------------------------------

+        1    /usr/lib/jvm/java-6-openjdk/jre/bin/java

2    /usr/lib/jvm/java-6-sun/jre/bin/java

*         3    /usr/lib/jvm/java-1.5.0-sun/jre/bin/java

Press enter to keep the default[*], or type selection number:

输入 有包含 "sun" 的行的前面的数字。如上面显示，则输入3，然后回车确定。（编译android需要配置java5
）

sudo update-alternatives --config javac

操作和前面类似。

4 配置JAVA环境变量:

sudo gedit /etc/environment

在其中添加如下两行：

JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun

ANDROID_JAVA_HOME=$JAVA_HOME

CLASSPATH=.:/usr/lib/jvm/java-1.5.0-sun/lib

要使配置生效必须重启机器或者在命令行输入

. /etc/environment

5 配置JVM的优先级: (ubuntu9.10如果没有安装多个java虚拟机的话可以跳过这一步。)

sudo gedit /etc/jvm

将文件中的

/usr/lib/jvm/java-1.5.0-sun

这一行填入到配置块的顶部

（二）安装交叉编译器及其他编译工具

1.1.1

FLEX

Flex is a tool for generating scanners.

# sudo apt-get install flex

1.1.2

BISON

Bison is a general-purpose parser generator.

# sudo apt-get install bison

1.1.3

gperf

gperf is a program that generates perfect hash functions.

# sudo apt-get install gperf

1.1.4

libsdl-dev

SDL is a library that allows programs portable low level access to a video framebuffer, audio output, mouse, and keyboard.

# sudo apt-get install libsdl-dev

1.1.5

libesd0-devl

This program is designed to mix together several digitized audio streams for playback by a single device.

# sudo apt-get install

libesd0-dev

1.1.6

libwxgtk2.6-dev

This package provides files needed to compile wxWidgets programs.

# sudo apt-get install
libwxgtk2.6-dev

1.1.7

zlib1g-dev

zlib is a library implementing the deflate compression method.

# sudo apt-get install zlib1g-

dev

1.1.8

build-essential

This package contains an informational list of packages which are considered essential for building Debian packages.

# sudo apt-get install

build-essential

1.1.9

libncurses5-dev

This package contains the header files, static libraries and symbolic links.

# sudo apt-get install
libncurses5-dev

1.1.10
Uboot-mkimage

This package contains the mkimage utility.

# sudo apt-get install uboot-mkimage

1.2

Cross Tool

1. Copy the cross tool package to /usr/local/arm

If the arm directory is not exist in host pc then create the directory

# mkdir /usr/local/arm

# cp 4.3.1-eabi-armv6-20080707.tar.bz2 /usr/local/arm

2. unzip the code using tar command

# tar xvjf 4.3.1-eabi-armv6-20080707.tar.bz2

3. Add source path in your environment file

# vi ~/.bashrc

Add the source path
PATH=$PATH:/usr/local/arm/4.3.1-eabi-armv6/usr/bin
# source ~/.bashrc

4 unzip the code using tar command

# tar xvjf cross-4.2.2-eabi.tar.bz2 -C /usr/local/arm

1.3

Build Android

1. 用tar命令将源码解压到某路径下path/.

2. Move to android directory and build it.

# cd path/android（这个是你解压android源码后的路径）

# make（-j2这步是编译，可能会需要很长时间）
