回复: 【提问】才学QT。这么简单的程序在错了？在kdevelop下编译出错~

对，写Qt程序用qmake管理工程比较的方便些。

下面是引用magicoy于2005-08-25 16:36发表的:
#include
#include
int main( int argc, char *argv[] )
.......
应该是
QApplication a(argc, argv);

#include

QApplication a( argc, argv );
QPushButton hello( "Hello world!", 0 );
hello.resize( 100, 30 );
a.setMainWidget( &hello );
hello.show();
return a.exec();

不会吧，上面的程序根本用不着moc。肯定是你工程的问题。
