深度探索Linux操作系统第二章：系统构建和原理解析-工具编译
虚拟机上操作系统：ubuntu-12.04-desktop-i386.iso
指导书：《深度探索Linux操作系统：系统构建和原理解析》王柏生
准备工作：
wangwei@wangwei-VirtualBox:~$sudo apt-get update
wangwei@wangwei-VirtualBox:~$sudo apt-get install upgrate
安装服务器：
wangwei@wangwei-VirtualBox:~$sudo apt-get install openssh-server
wangwei@wangwei-VirtualBox:~$sudo /usr/sbin/sshd
安装需要的软件：
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密码：
wangwei@wangwei-VirtualBox:~$sudo passwd root
Enternew UNIX password:
Retypenew UNIX password:
passwd:password updated successfully
进入根用户：
wangwei@wangwei-VirtualBox:~$su
Password:
root@wangwei-VirtualBox:/home/wangwei#
创建用户组和用户主：
root@wangwei-VirtualBox:/home/wangwei#groupadd vita
root@wangwei-VirtualBox:/home/wangwei#useradd -m -s /bin/bash -g vita vita
增加vita的超级权限：
root@wangwei-VirtualBox:/home/wangwei#echo 'vita ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers.d/vita
检查vita文件是否写入vitaALL=(ALL) NOPASSWD: ALL内容：
root@wangwei-VirtualBox:/home/wangwei#vim /etc/sudoers.d/vita
设置环境变量：
root@wangwei-VirtualBox:/home/wangwei#vim /home/vita/.bashrc
在.bashrc中写入以下内容
#vita export变量注释。
#unsetLANG设置为英语已经被注释，因为使用的英语版ubuntu12。
export HOST=$MACHTYPE
export BUILD=$HOST
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
创建文件夹和挂载sda7:
root@wangwei-VirtualBox:/home/wangwei#mkdir /vita
root@wangwei-VirtualBox:/home/wangwei#df -h

wangwei@wangwei-Inspiron-7520:~$sudo scp -r /home/wangwei/source/* 192.168.1.107:/vita/source/ 从主机开始向虚拟机发送source中的所有文件。
更改vita目录的属主和属组：
root@wangwei-VirtualBox:/vita#chown -R vita.vita /vita
切换用户为vita:
root@wangwei-VirtualBox:/vita#su – vita
vita@wangwei-VirtualBox:~$
检查设置的环境变量是否运行：
vita@wangwei-VirtualBox:~$env

定义工具链相关的环境变量：
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 STRIP="$TARGET-strip"
export DESTDIR=$SYSROOT
unset PKG_CONFIG_PATH
exportPKG_CONFIG_LIBDIR=$SYSROOT/usr/lib/pkgconfig:SYSROOT/usr/share/pkgconfig
不会pkg-config，这里只是把shell代码打出来：
#!/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
