移植过程：

1. 编译QT4.7.4

1.1 通过setenv.sh shell脚本设置交叉编译工具链路径

#cd /home/wenxy/src/QT; . setenv.sh; cd qt-everywhere-opensource-src-4.7.4

 

1.2 配置QT

#./configure -embedded -help

#./configure -embedded arm -xplatformqws/linux-arm-g++ -depths 4,8,12,16,24,32-no-qt3support -qt-mouse-linuxtp

 

或者支持所有的颜色深度

#./configure -embedded arm -xplatformqws/linux-arm-g++ -depths all -no-qt3support-qt-mouse-linuxtp

 

如果没有安装g++，则在线安装

#apt-get install g++

否则会报错：

Creating qmake. Pleasewait...

make: g++: Command notfound

make: *** [project.o]Error 127

 

1.3 配置完成后，运行编译命令

#make

编译过程看计算机配置，几个小时。摘抄最后的编译信息如下：

整个目录大小

root@wenxy-desktop:/home/wenxy/src/QT/qt-everywhere-opensource-src-4.7.4#du -sh

1023M   .

源代码500MB左右。

 

2. 把编译好的QT4.7.4库和SDK中自带的例子程序copy到开发板上

2.1 Run demo in development board

建立以下目录：/usr/local/Trolltech/QtEmbedded-4.7.4-arm

 

Copy QT lib and demos to development board

#mount -t nfs -o nolock192.168.1.160:/home/wenxy/src/QT/qt-everywhere-opensource-src-4.7.4/mnt/nfs

#cp –Rf /mnt/nfs/lib /usr/local/Trolltech/QtEmbedded-4.7.4-arm

#cp –Rf /mnt/nfs/demos /usr/local/Trolltech/QtEmbedded-4.7.4-arm

 

 

设置环境变量

#exportPATH=$PATH:/usr/local/Trolltech/QtEmbedded-4.7.4-arm

#exportLD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/Trolltech/QtEmbedded-4.7.4-arm/lib

 

运行例子程序

#cd /usr/local/Trolltech/QtEmbedded-4.7.4-arm/demos/embedded/anomaly

#./anomaly -qws &

出现错误：

#./anomaly -qws &

root@imx28evk/usr/local/Trolltech/QtEmbedded-4.7.4-arm/demos/embedded/anomaly$blit_setup(): Screen depth 32 not supported!

[1] + Aborted                    ./anomaly –qws

解决方法：重新配置QT(-depths参数设置成4,8,12,16,24,32)，再次编译，使用这次生成的QT lib即可。

 

#cd /usr/local/Trolltech/QtEmbedded-4.7.4-arm/demos/embeddeddialogs

#./embeddeddialogs -qws &

 

#cd /usr/local/Trolltech/QtEmbedded-4.7.4-arm/demos/mainwindow

#./mainwindow -qws &

运行后，LCD屏会显示QT的图形用户界面（GUI）。插上USB鼠标和USB键盘，就可以进行操作。如果要支持触摸屏，需要安装触摸屏驱动，TSLIB电阻屏校正程序。
