[완료]QT 4.4.0 컴파일 질문입니다.

#include <QtGui/QApplication> //이부분은 <QApplication> 원래는 이렇게 되어있었는데요 앞에 QtGui 을 넣어줘야 컴파일되더군요..
#include <QtGui/QLabel>
 
int main(int argc,char **argv)
{
  QApplication app(argc,argv);
  QLabel *hello = new QLabel("<font color=blue>Hello <i>Qt!</i>""</font>",0);
  hello->show();
  return app.exec();
}

$ gcc -o hello -L$QTDIR/lib -L/usr/X11R6/lib -lqt-mt -lX11 -lXext hello.o //그리고 여기서도 -lqt 하니깐 안되더군요. -lqt-mt 하니깐 되었습니다.
hello.o: In function `main':
hello.cpp:(.text+0x2c): undefined reference to `QApplication::QApplication(int&, char**, int)'
