Ubuntu9.10默认安装的纯净系统，没装任何其他软件。

　　1.下载源码android-2.1_r2，直接make

　　2.出错及解决如下：

　　(1)/bin/bash: bison: command not found

　　解决：a@ubuntu:~/work/android-2.1_r2$ sudo apt-get install bison

　　(2)make: *** No rule to make target `Please-install-JDK-5.0,-update-12-or-higher,-which-you-can-download-from-java.sun.com',

　　needed by `out/target/common/docs/api-stubs-timestamp'. Stop.

　　解决：安装JDK 5.0

　　1)：根据官方文档里所说,源代码的编译必须使用JDK5才能编译的了，所以这里我们使用jdk5

　　2): 需要先更新源,在终端里执行 sudo vim /etc/apt/sources.list

　　3): 在source.list里把以下2行拷贝到文档最后面：

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

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

　　保存退出。

　　4): 执行 sudo apt-get update 更新源.

　　5): 配置编译环境并下载JDK5：sudo apt-get install sun-java5-jdk

　　(3)/bin/bash: g++: command not found

　　make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libhost_intermediates/pseudolocalize.o] Error 127

　　解决：a@ubuntu:~/work/android-2.1_r2$ sudo apt-get install build-essential

　　http://hi.baidu.com/maxgoto/blog/item/fa000f7bf01135f80ad187d8.html 最近下载了Android 2.1源码，在Ubuntu 9.10上做了一次编译，由于系统为纯净系统，之前没有进行过任何Android的编译，所以需先安装一些必要软件。编译过程参考网上一些文章，做下笔记如下，以供参考：

1. 下载或更新Android源码 至最新，截止到前天(04-09)好像是2.1-r2.

2. Android 要求的 jdk 1.5,而Ubuntu9.10的源里只有JDK1.6. 目前网上解决方法有两种：
    解决方法一： 安装JDK1.5
   1） 根据官方文档里所说,源代码的编译必须使用JDK5才能编译的了，所以这里我们使用jdk5
   2） 需要先更新源,在终端里执行 sudo vim /etc/apt/sources.list
   3） 在source.list里把以下2行拷贝到文档最后面：
        deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse
        deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
        保存退出。
   4） 执行 sudo apt-get update 更新源.
   5）配置编译环境并下载JDK5：sudo apt-get install sun-java5-jdk

3. 安装编译过程中必需软件 。根据网上高人的经验，这是编译的最小工具软件集。
    $sudo apt-get install build-essential
    $sudo apt-get install zlib1g-dev
    $sudo apt-get install flex
    $sudo apt-get install libncurses-dev
    $sudo apt-get install libx11-dev
    $sudo apt-get install gperf

4. make .经过漫长的编译过程，编译成功。
