我的实践：

在centos6.7 X64位机器上：

yum install xulrunner.i686

yum install libXtst.i686

下面是一些网络搜索到的资料：

项目中，实现嵌入式设备开发，后台应用开发，均采用C/C++语言，基于Linux的开发；所不同的是，嵌入式平台采用32位Linux系统，应用服务程序采用64位Linux系统。开发过程需要将两种开发环境，在同一台物理机上实现。

嵌入式开发环境构建时，安装的交叉编译环境，需要32位的开发库。本文中，提供一种在线安装方法(需要root用户权限进行)：

$sudo yum install xulrunner.i686

$sudo yum install libXtst.i686

如果采用ubuntu环境，执行如下命令(同样需要root用户权限)：

1. sudo apt-get update

2.sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

Linux的有些软件需要32位运行库才能运行，如Dr.com客户端等

yum在线安装：

sudo yum install xulrunner.i686

或者： sudo yum install ia32-libs.i686

ubuntu下： sudo apt-get install ia32-libs

PS:可以查看一下当前源库里有没有ia32-libs: yum list|grep ia32-libs

centos 安装ia32-libs
