交叉编译工具链的安装

步骤1：打开虚拟机，在/usr/local/下创建/usr/local/arm文件夹
步骤2：先将安装包从Windows中弄到linux中去。可以用共享文件夹，也可以用Samba，也可以cuteftp。
步骤3：解压。tar -jxvf arm-2009q3.tar.bz2
到此相当于程序已经安装完毕，真正的应用程序安装在/usr/local/arm/arm-2009q3/bin目录下

安装后的测试

到真正的应用程序的安装目录下（也就是/usr/local/arm/arm-2009q3/bin），去执行arm-linux-gcc -v
执行方法是：./arm-none-linux-gnueabi-gcc -v
执行后可以得到一长串输出，其中有“gcc version 4.4.1 ”字样，即表示安装成功。

遇到失败的提示

执行./arm-none-linux-gnueabi-gcc -v
提示

bash: ./arm-none-linux-gnueabi-gcc: No such file or directory

百度相关问题大概为64位Ubuntu系统安装32位程序需要安装相应的32位兼容包，百度给出以下解决方案：

1.执行：sudo apt-get install lib32z1

结果

结果依旧不行。

2.执行：sudo apt-get install lib32ncurses5 lib32z1 lib32stdc++6 libstdc++6

结果 

root@ubuntu:/usr/local/arm/arm-2009q3/bin# ./arm-none-linux-gnueabi-gcc -v

Reading package lists... Done
Building dependency tree

Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  lib32z1

E: Package 'ia32-libs' has no installation candidate


结果依旧不行。

4.执行：sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

结果 

root@ubuntu:/usr/local/arm/arm-2009q3/bin# sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

有新的发现

昨晚弄得头晕脑胀，继续昨晚的apt-get update连接不上，今天下班回来，打开虚拟机浏览器发现网页打不开，原来是虚拟机网络出现了故障。
百度了一下Ubuntu无法联网找到一下解决办法：
sudo service network-manager stop
sudo rm /var/lib/NetworkManager/NetworkManager.state
sudo service network-manager start
验证浏览器，发现网络已正常。
1.打开Ubuntu的Software & Updates把更新源切换至国内的阿里云的源http//:mirrors.aliyun.com/ubuntu
2.执行：sudo apt-get install lib32z1成功
3.执行：./arm-none-linux-gnueabi-gcc -v成功显示相应的版本号。

至此GCC交叉编译工具链安装成功。??ヽ(°▽°)ノ?
