編譯android源碼

首先搭建android編譯環境。

      （一）安裝配置java5

      1 先安裝java6(編譯android需要java5，此處為推薦)

         開啟終端，執行以下命令，或使用Adept/新立得軟體管理器，在其中分別搜尋"sun-java6-jre"和"sun-java6-jdk"並標記安裝。 

         sudo apt-get install sun-java6-jre
         如果空間富裕，建議安裝一個JDK。

         sudo apt-get install sun-java6-jdk
         提示：安裝過程中需要你回答是否同意使用協議（終端中紅藍色的提示介面），此時按tab鍵至OK，再按斷行符號即可正常安裝。

      2 安裝java5

        

　　　　　　如果是ubuntu910版本，安裝java5時需要更新源，方法：

　　       將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 設定當前預設的java解譯器和編譯器： (ubuntu9.10如果沒有安裝多個java虛擬機器的話可以跳過這一步。)

         sudo update-alternatives --config java
         執行後會出現類似如下的畫面:

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:

輸入 有包含 "sun" 的行的前面的數字。如上面顯示，則輸入3，然後斷行符號確定。（編譯android需要配置java5）

sudo update-alternatives --config javac

操作和前面類似。

       4 配置JAVA環境變數:

     sudo gedit /etc/environment

        在其中添加如下兩行：

     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

        要使配置生效必須重啟機器或者在命令列輸入

     . /etc/environment

       5 配置JVM的優先順序: (ubuntu9.10如果沒有安裝多個java虛擬機器的話可以跳過這一步。)

     sudo gedit /etc/jvm

        將檔案中的

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

        這一行填入到配置塊的頂部

 

 （二）安裝交叉編譯器及其他編譯工具

 

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命令將源碼解壓到某路徑下path/.     

2. Move to android directory and build it.

       # cd path/android（這個是你解壓android源碼後的路徑）

       # make（這步是編譯，可能會需要很長時間）
