縮小VDI檔案大小

於客體端

1. sudo apt-get install zerofree
2. 重開機進入Recovery Mode
3. mount -n -o remount,ro -t ext3 /dev/sda1 /
4. zerofree -v /dev/sda1

於主體端

• VBoxManage modifymedium XXX.vdi --compact

chroot測試SDK出現cat /proc/cpuinfo錯誤

用chroot測試SDK，make時出現下面的錯誤
cat: /proc/cpuinfo: No such file or directory

解決，

sudo mount --bind /proc <chroot dir>/proc

Build openWRT Image

1. sudo tar -Jxv -f xxx-openwrt-sdk-xxx.tar.bz2  
2. apt-get install subversion
   apt-get install wget
   apt-get install libncurses5-dev
   apt-get install zlib1g-dev
   apt-get install gawk
   apt-get install unzip
   apt-get install python
   apt-get install git
   apt-get install file 
3. git init
4. cp util-linux-2.24.1.tar.xz到dl目錄
5. make menuconfig 
6. make V=s (第一次要連網)

P.S.

1. 因util-linux-2.24.1.tar.xz已從server拿掉，自行下載copy到dl目錄。
2. 遇到底下錯誤要先做git init

Build openWRT發生base-files/etc/sdk.version: No such file or directory

下"git init"即可解決
