• 开始

  首先我们先创建一个目录来存放Qt5的源代码以及交叉编译所需要的所有文件，我选择在当前用户家目录下创建一个叫做“opt”的目录。

  1	diveinedu@debian :~$ mkdir  ~/opt

  2	diveinedu@debian :~$ cd  ~/opt

  然后，下载以下文件：

  下载Raspbian Wheezy 镜像  (这里下载 [raspberrypi.org]):

  1	diveinedu@debian :~/opt$ wget  http://downloads.raspberrypi.org ... wheezy-raspbian.zip

  2	diveinedu@debian :~/opt$unzip  2013-02-09-wheezy-raspbian.zip

  下载解压完后挂载镜像：

  1	diveinedu@debian :~/opt$ sudo  mkdir  /mnt/rasp-pi-rootfs

  2	diveinedu@debian:~/opt$ sudo mount  -o loop,offset=62914560 2013-03-09-wheezy-raspbian.img    /mnt/rasp-pi-rootfs
