BUSYBOX编译备忘录
编译busybox的组合：
busybox-1.0.0
arm-linux-gcc-2.95.3 (AT91rm9200开发板)
经典参考：
http://busybox.net/downloads/
下载busybox
http://husaberg.toby-churchill.com/balloon/releases/v0.7/roots/
文件系统制作
移植基本过程：
1.
到http://busybox.net/downloads/busybox-1.7.3.tar.bz2下载busybox;
2.
解压busybox1.7.3
tar jxvf busybox-1.7.3.tar.bz2
3. make defconfig
4.
make menuconfig
在[build options]中选择[Build busybox as a static binary]
主要是C库的连接方式，安装目录等。
5. make
6. 创建rootfs目录
7. make
install
编译过程可能出现以下错误，解决方法如下：
可能会出现的错误：
1. 出现如下错误
