很多朋友在移植Qt-embedded 4.xx的时候都使用了友善之臂公司提供的交叉编译器，

虽然Qt与Qt应用程序都编译成功，但运行Qt应用程序时却经常会出现段错误(Segmentation Fault)，

可以尝试使用openmoko（一个开源手机项目）提供的编译器，同样是EABI，版本为4.1.2

http://www.qtopia.net/modules/mydownloads/singlefile.php?lid=38

经测试，运行Qt应用程序时不会出现段错误(Segmentation Fault)

详细的移植步骤见本人的博客：
移植Qt-embedded 4.5.2 for mini2440

good luck!

不错，试一试！Thanks

程序 qt-embedded-linux-opensource-src-4.5.0/src/gui/embedded/qscreenlinuxfb_qws.cpp
作如下修改：

410行：
/*            //EmbedSky_del start 20091208
    canaccel = useOffscreen();
    if(canaccel)
        setupOffScreen();
*/            //EmbedSky_del end 20091208
    canaccel = false;

706行：
/*                //EmbedSky_del start 20091208
    if (canaccel) {
        *entryp=0;
        *lowest = mapsize;
        insert_entry(*entryp, *lowest, *lowest);  // dummy entry to mark start
    }
*/                //EmbedSky_del end 20091208
    canaccel = false;

可能解决segmentation fault问题，请大家测试

修改了qscreenlinuxfb_qws.h，用友善之臂提供的arm-linux-gcc-4.3.2.tgz重新编译QT4.5.0-arm（release方式），试了2个程序可以正常运行。

NOTE: This is a HACK, and not a pretty one either. It makes sure that it hardcoded doesn't use off-chip graphic memory. I don't use off-chip graphic memory, but if you do, this hack is useless.
