系统：ubuntu12.04 qt版本：4.8.6
pc QT位置：/usr/local/Trolltech/qt-everywhere
pc端/etc/profile配置:
#for arm
export QTDIR=/usr/local/Trolltech/qt-everywhere
export PATH=$QTDIR/bin:/source/arm-gcc-4.6.4/bin PATH
export LD_LIBRARY_PATH=$QTDIR/libLD_LIBRARY_PATH
export QMAKESPEC=$QTDIR/mkspecs/qws/linux-arm-g++
#echo $PATH 环境变量
/usr/local/Trolltech/qt-everywhere/bin:/source/arm-gcc-4.6.4/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/source/arm-gcc-4.6.4/bin:/source/arm-gcc-4.6.4/bin
ARM版qt位置：
usr/local/Trolltech/qt-everywhere
ARM端/etc/profile配置:
export LD_LIBRARY_PATH=/usr/local/Trolltech/qt-everywhere/lib:/usr/local/lib
qt代码：
#include <QApplication>
#include <QDialog>
#include <QPushButton>
#include <QLineEdit>
int main(int args,char**argv)
{
QApplication app(args,argv);
QDialog dlg;
dlg.resize(400,300);
dlg.move((1024-400)/2,(768-300)/2);
QPushButton btn(&dlg);
btn.resize(100,30);
btn.move(100,100);
btn.setText("ok");
QLineEdit edt(&dlg);
edt.resize(100,30);
edt.move(100,200);
edt.setText("ok");
dlg.setVisible(true);
return app.exec();
}
pc使用qte编译后，放入arm平台执行，提示：
[root@S5PV210 hello]# ./hello -qws
QLock: Lock: Cannot create semaphore /tmp/qtembedded-0/QtEmbedded-0 'd' (38, Function not implemented)
Cannot get display lock

注：
内核使用3.0.8， System V IPC选项已经开启
