Mini2440官方所提供的arm-Linux-gcc是基于32位Linux系统的，在64位Linux中运行会出错[1]。在64位机时代里，继续使用32位Linux进行开发就显得有点out了。针对上述背景，本文在64位Linux中制作arm-linux-gcc工具，主要开发环境如下：
- Ubuntu 16.04（64bit） http://www.linuxidc.com/Linux/2016-04/130466.htm
- arm-linux-gcc 4.6.3
- Buildtroot
下载 arm-linux-gcc 4.4.3

1 Buildroot
1.1 配置
下载Buildroot源码并解压，进入其目录执行下述命令启动配置界面：
make menuconfig
配置界面如下：
第一次执行make menucofig时，可能会出错：

mkdir -p /home/onesea/Mini2440/Buildroot/buildroot-2016.02/output/build/buildroot-config/lxdialog

根据上述错误提示，当前系统缺乏ncurses库，执行下述命令进行安装即可：
sudo apt-get install libncurses-dev
