[Linuxidc@localhost dl]$ cd buildroot-2011.11/
[Linuxidc@localhost dl]$ cp dl/buildroot-2011.11-config_arm920t .config

注：buildroot-2011.11-config_arm920t 在sourcecode里面，路径如下：

/home/Linuxidc/source/embededproject-code/doc/buildroot/config/buildroot-2011.11-config_arm920t

[Linuxidc@localhost dl]$ export TERM=vt100
[Linuxidc@localhost dl]$ make menuconfig
[Linuxidc@localhost dl]$ make

注：在make的时候，我们可能出现一种情况就是：系统提示我们的makeinfo没有安装，这是因为我们的系统缺少一个texinfo的软件包，我们可以把这个软件包下载安装，然后再make，就不会出现这样的问题。

下载地址如下：http://ftp.gnu.org/gnu/texinfo/

[Linuxidc@localhost dl]$ tar -zxf 解压缩软件包

[Linuxidc@localhost dl]$ ./configure 配置

[Linuxidc@localhost dl]$ make  编译

[Linuxidc@localhost dl]$ make install 安装

继续之前的工作：make的时候，看每个人的PC的配置，配置越高，make的时间就会短一点，一般在半小时之内能搞好。

[Linuxidc@localhost dl]$    make
[Linuxidc@localhost ~]$ /opt/buildroot-2011.11/arm920t/usr/bin/arm-linux-gcc
