ubuntu64位安装32位依赖库，并安装njit-client

方法一:
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs




PS:这种方法肯定能安装上ia32-libs，但由于添加的是13.04的源，所以有没有混淆暂时不清楚，
网上也有很多用新立德软件包管理器这样做；够狠，你就这么干。也可以这么安装了ia32-libs后，
把/etc/apt/sources.list.d目录下的ia32-libs-raring.list删掉，然后再sudo apt-get update








方法二:
切换至中科大的源 http://uestc.edu.cn
 然后apt-get update
接着apt-get install ia32-libs
如果终端出现:

自己去网上搜索这三个包,然后安装.
或者使用以下网址:


https://packages.debian.org/wheezy/i386/libgphoto2-port0/download


https://packages.debian.org/wheezy/i386/libgphoto2-2/download


https://launchpad.net/ubuntu/raring/i386/libgd2-xpm/2.0.36~rc1~dfsg-6.1ubuntu1


安装后再执行apt-get install ia32-libs

没有意外应该装上了.
