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：
$ 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 jaunty multiverse
deb 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：
$ sudo apt-get install build-essential
