[root@localhost ~ ] # tar xvf root_qtopia.tar.bz2
[root@localhost root_qtopia ] # cd root_qtopia/
可先删除原有的qtopia系统
[root@localhost root_qtopia ] # rm -rf opt/Qtopia   #确保路径正确
 
 
二、加入tslib及qt4.7.2

一、下载qt Embedded 4.7.2的源码，从http://qt.nokia.com上可获取
 
二、解压源代码包并进入相应目录，先进行配置，可写一个配置文件运行之以自动配置
   如编写自动配置文件autoconfig.sh，内容如下：
 
#!/bin/bash
./configure /
-prefix /usr/local/qt-arm9-4.7.2 / https://blog.youkuaiyun.com/homking/article/details/6299356https://blog.youkuaiyun.com/homking/article/details/6299356homkingSat, 02 Apr 2011 22:08:00 +0800目标机是mini2440
 
下载最新tslib源码包，如tslib1.4.tar.bz2
 
解压后进入相应目录，然后作如下操作：
[root@localhost tslib ] # ./autogen.sh    # 自动生成configure文件
[root@localhost tslib ] # ./configure --prefix=/usr/local/tslib/ --host=arm-linux ac_cv_func_]]>https://blog.youkuaiyun.com/homking/article/details/6295759https://blog.youkuaiyun.com/homking/article/details/6295759homkingFri, 01 Apr 2011 21:52:00 +0800https://blog.youkuaiyun.com/homking/article/details/6288256https://blog.youkuaiyun.com/homking/article/details/6288256homkingWed, 30 Mar 2011 11:33:00 +0800      假如本机上安装了多个Qt版本或者说升级过Qt库，那么用QtCreator编写程序的时候可能会出现这种情况：自动补全时有很多库函数或头文件不见了，或者是不正确。现象是：
      如输入
      #include
此时后面自动补全的列表里没有原先诸如QLabel等的头文件等

解决：
一、重新配置QTDIR变量

这组命令以指定模式搜索文件，并通知用户在什么文件中搜索到与指定的模式匹配的字符串，并打印出所有包含该字符串的文本行，在该文本行的最前面是该 行所在的文件名。 grep 命令一次只能搜索一个指定的模式；egrep 命令检索扩展的正则表达式（包括表达式组和可选项）；fgrep 命令检索固定字符串，它不识别正则表达式，是快速搜索命令。
这组命令在搜索与定位文件中特定的主题方面非常有用。要搜索的模式可以被认为是一些关键词，您可以用它们来搜索文件中包含的这些关键词]]>
