用Qtopia2.2写了一个按一个按钮可以弹出进度框的程序，但是编译出错。
槽部分程序如下：
QProgressDialog progress=new QProgressDialog(QString::fromLocal8Bit("progress"),QString::fromLocal8Bit("fhghj"),100,this,"progress",TRUE);
progress->show();
int x=0;
int i=0;
while(x<=100)
{
for(i=0;i<ytime;i++)
{
progress->setProgress(x);
x++;
}
}
错误如下：

rm -f .moc/release-shared/moc_display.cpp
rm -f .obj/release-shared/display.o .obj/release-shared/main.o
