qt-everywhere-opensource-src-4.8.2安装好后，编译代码出错.
我安装好了qt之后编译以下hello world代码报错，请问是怎么回事？
#include <QApplication>
#include <QPushButton>
int main(int argc, char *argv[])
{
QApplication app(argc,argv);
QPushButton b("Hello World !");
b.show();
QObject::connect(&b,SIGNAL(clicked()),&app,SLOT(quit()));
return app.exec();
}
错误如下：

make: *** [b.o] Error 1
等等，还有一堆这样的错误就没全部贴出来了。
我检查过了类似于/usr/include/qt4/QtCore/这样的路径，是存在像qstring.h这样的头文件的。求教各位高手~
