ubuntu14.04编android2.3.1的一些坑

1、

apt-cache policy name
获得已安装的name 的version

2、android 2.3.1在ubuntu14.04上编译的错误

*gcc 不对：安装4.4的gcc和g++

*Zgnote.c报错：用下面的patch

有一处少了一个头文件，原因是zlib1g-dev有个头文件修改了路径，及zconf.h放到了/usr/include/x86_64-linux-gnu/，所以将其拷贝到/usr/include/下即可了

*Can't locate Switch.pm in

sudo apt-get install libswitch-perl

*Unknown parameter

gcc版本太高，用update-alternative配置一下

Problem when installing CACTI
G++: selected multilib '32' not installed.
Install the multilib for g++
In Ubuntu, we just input 

 sudo apt-get install g++-multilib

However, the g++ we use is not the latest version, it is g++ - 4.4, so we should also install this. 
Just 

 sudo apt-get install g++-4.4-multilib
