郁闷

今天编译QT教学文档中的例1 1 HELLO顺利通过 2 调用退出   就出问题了 main.cpp #include <qapplication.h>
#include <qpushbutton.h>
#include <qfont.h>

int main( int argc, char **argv )
{
    QApplication a( argc, argv );

    QPushButton quit( "Quit", 0 );
    quit.resize( 75, 30 );
    quit.setFont( QFont( "Times", 18, QFont::Bold ) );

    QObject::connect( &quit, SIGNAL(clicked()), &a, SLOT(quit()) );

    a.setMainWidget( &quit );
    quit.show();
    return a.exec();
}
其中库文件 <qpushbutton.h> 在原库目录下是没有的,所以要调用 qpushbutton.h

make时出现make

qpushbutton.h:61: Error: syntax error
make: *** [moc_qpushbutton.cpp] 错误 1
