準備工作：
wangwei@wangwei-VirtualBox:~$sudo apt-get update
wangwei@wangwei-VirtualBox:~$sudo apt-get install upgrate
安裝服務器：
wangwei@wangwei-VirtualBox:~$sudo apt-get install openssh-server
wangwei@wangwei-VirtualBox:~$sudo /usr/sbin/sshd
安裝需要的軟件：
wangwei@wangwei-VirtualBox:~$sudo apt-get install g++
wangwei@wangwei-VirtualBox:~$sudo apt-get install gawk
wangwei@wangwei-VirtualBox:~$sudo apt-get install m4
wangwei@wangwei-VirtualBox:~$sudo apt-get install gcc-multilib
wangwei@wangwei-VirtualBox:~$sudo apt-get install build-essential
wangwei@wangwei-VirtualBox:~$sudo apt-get install texinfo
更改root密碼：
wangwei@wangwei-VirtualBox:~$sudo passwd root
Enternew UNIX password:
Retypenew UNIX password:
passwd:password updated successfully
進入根用戶：
wangwei@wangwei-VirtualBox:~$su
Password:
root@wangwei-VirtualBox:/home/wangwei#
創建用戶組和用戶主：
root@wangwei-VirtualBox:/home/wangwei#groupadd vita
root@wangwei-VirtualBox:/home/wangwei#useradd -m -s /bin/bash -g vita vita
增加vita的超級權限：
root@wangwei-VirtualBox:/home/wangwei#echo 'vita ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers.d/vita
檢查vita文件是否寫入vitaALL=(ALL) NOPASSWD: ALL內容：
root@wangwei-VirtualBox:/home/wangwei#vim /etc/sudoers.d/vita
設置環境變量：
root@wangwei-VirtualBox:/home/wangwei#vim /home/vita/.bashrc
在.bashrc中寫入以下內容
#vita export變量註釋。
#unsetLANG設置爲英語已經被註釋，因爲使用的英語版ubuntu12。
export HOST=$MACHTYPE

export TARGET=i686-none-linux-gnu
export CROSS_TOOL=/vita/cross-tool
export CROSS_GCC_TMP=/vita/cross-gcc-tmp
export SYSROOT=/vita/sysroot
PATH=$CROSS_TOOL/bin:$CROSS_GCC_TMP/bin:/sbin:/usr/sbin:$PATH
創建文件夾和掛載sda7:

wangwei@wangwei-Inspiron-7520:~$sudo scp -r /home/wangwei/source/* 192.168.1.107:/vita/source/ 從主機開始向虛擬機發送source中的所有文件。
更改vita目錄的屬主和屬組：
root@wangwei-VirtualBox:/vita#chown -R vita.vita /vita
切換用戶爲vita:
root@wangwei-VirtualBox:/vita#su – vita
檢查設置的環境變量是否運行：

定義工具鏈相關的環境變量：
vita@wangwei-VirtualBox:/$vim /home/vita/.bashrc
export CC="$TARGET-gcc"
export CXX="$TARGET-g++"
export AR="$TARGET-ar"
export AS="$TARGET-as"
export RANLIB="$TARGET-ranlib"
export LD="$TARGET-ld"
export STRIP="$TARGET-strip"
export DESTDIR=$SYSROOT
unset PKG_CONFIG_PATH
exportPKG_CONFIG_LIBDIR=$SYSROOT/usr/lib/pkgconfig:SYSROOT/usr/share/pkgconfig
不會pkg-config，這裏只是把shell代碼打出來：
#!/bin/bash
HOST_PKG_CFG=/usr/bin/pkg-config
if[ ! $SYSROOT ]; then
echo"Please make sure you are in cross-comile environment!"
exit1
fi
$HOST_PKG_CFG--exists $*
if[ $? -ne 0 ]; then
exit1
fi
if$HOST_PKG_CFG $* | sed -e"s/-I/-I\/vita\/sysroot/g;s/-L/-L\/vita\/sysroot/g"
then
exit0
else
exit1
fi
