qtopia 执行qpe问题 [复制链接]

我今天编译了qtopia，然后下载到板子上去，我的板子是min2440，当运行qpe时，屏幕没有反应，且出现如下错误
No IRDA devices found!                                                          
Segmentation fault    

我的configure如下
echo "yes"| ./configure -silent -release -image /mnt/nfs/qtopia -prefix /mnt    /nfs/qtopia -xplatform linux-arm-g++ -arch arm -no-qvfb -displaysize 240x320     -no-modem -extra-qtopiacore-config "-release -xplatform qws/linux-arm-g++ -    embedded arm -opengl -qconfig qpe -qt-sql-sqlite -depths 4,8,16,32 -qt-kbd-usb -no-kbd-tty -no-mouse-linuxtp -qt-mouse-tslib -I/mnt/nfs/tslib/include -L/mnt/nfs/tslib/lib"

屏幕没有反应，先用examples/qws/framebuffer 测试一下你的framebuffe能否正常工作。

No IRDA device found !这个应该不会影响程序运行。

Segmentation fault
这种错误现象太常见了，没人是没法告诉你问题可能出在哪里的。

建议你用gdb跟踪一下，程序在什么地方出错了。

一些程序使用-qws运行有图像，说名framebuffer是正常，开发板上的程序能用gdb吗

在执行如下语句时
QAbstractServerInterface *interface =
        qtopiaWidget<QAbstractServerInterface>(0, Qt::FramelessWindowHint);
用远程调试出现如下提示
Program received signal SIGSEGV, Segmentation fault.
0x00074030 in QBasicAtomic::init (this=0x0, x=1)
    at /home/jimmy/qt4/qtopia/qtopiacore/target/include/QtCore/../../../qt/src/corelib/thread/qatomic.h:68
68        { atomic = x; }

无调试执行qpe
出现如下
