从零开始移植QT4.8.5之三--linux下交叉编译QT运行库

这篇文章要实现的目标是在linux下交叉编译QT在嵌入式设备OK6410的运行库，最终在OK6410上运行QT演示程序。

1、触摸屏库文件安装tslib

首先如果嵌入式设备上有触摸屏，需要先移植tslib，这个不是本次的重点，所以我们就直接搭建编译的时候需要的tslib库，因为飞凌官方已经提供编译好了的库文件，所以之需要解压把库文件放到对应的位置就可以了。

编译好的tslib文件下载：http://download.youkuaiyun.com/detail/andylauren/9583536

解压到准备好的目录，这个目录需要记住，后面在编译QT的时候会用到，我的路径是/home/linux/arm/tslib目录下。

2、交叉编译qt-everywhere-opensource-src

需要在上一篇文章中的压缩包qt-everywhere-opensource-src-4.8.5.tar.gz，这里需要重新解压，因为如果已经configure过的会生成makefile文件，qt的configure会检测文件夹中是否有makefile，即使使用make clean也无法完全删除配置文件，在编译的时候可能会产生各种各样的路径、编译库不一致的错误，所以最好的方法就是每次编译之前都从新解压。

tar zxvf xxx.tar.gz

解压之后跳进解压后的文件夹

输入如下命令

echo yes | ./configure -opensource -embedded arm -xplatform qws/linux-arm-g++  -no-webkit -qt-libtiff -qt-libmng  -qt-mouse-tslib -qt-mouse-pc -no-mouse-linuxtp -prefix /home/linux/arm/qt-4.8.5-arm -I /home/linux/arm/tslib/include -L /home/linux/arm/tslib/lib

这里说明几个重要的设置

-prefix /home/linux/arm/qt-4.8.5-arm 这个是编译好的文件的目录，这个目录很重要，因为在开发板上也要将库文件放在这个目录中，所以需要谨慎选择。

-I /home/linux/arm/tslib/include          这个是刚刚解压好的tslib库的路径下的include

-L /home/linux/arm/tslib/lib                  这个是刚刚解压好的tslib库的路径下的lib

这几个需要根据自己的需求修改。

然后等着configure完成之后就可以经典的make&&make install

没有意外的话就会在/home/linux/arm/qt-4.8.5-arm路径下生成编译好的库文件

3、提取开发板需要的库文件

提取文件写了一个脚本，之需要其中的文件路径即可。下载地址：http://download.youkuaiyun.com/detail/andylauren/9583815

根据自己的需要修改home/linux/arm/qt-4.8.5-arm路径，如果QT的版本改变可以根据自己需要修改其中对应的版本号，4.8.5和4.8，其他的内容基本不需要改变。

然后在任何路径下运行这个脚本就可以。完成后在当前目录中会生成target-qte-4.8.5.tgz文件，我生成的文件在下面下载：http://download.youkuaiyun.com/detail/andylauren/9583545

之后把target-qte-4.8.5.tgz文件拷贝到开发板的根目录下，然后解压就可以了，之后就会在开发板的/home/linux/arm/qt-4.8.5-arm目录下会有QT库文件了。

到这个时候就可以在开发板上运行QT程序了，下面我们提供一个QT演示程序的脚本文件。

4、QT演示程序脚本文件

这个脚本只能在OK6410开发板4.3寸屏幕上运行，具体的内容请读者自己阅读，下一篇文章我们会一起自己写一个QT程序运行起来。那个时候我们来对自己的程序一些环境配置具体的讲解。
