我刚开始学习QT,第一个程序就是"Hello,word,"但在编译时出现了问题,请各位指导~~
源代码:(照抄的)
#include <qapplication.h>
#include <qpushbutton.h>
int main(int argc,char **argv)
{
QApplication a(argc,argv);
QPushButton hello("Hello,world!",0);
hello.resize(100,30);
a.setMainWidget(&hello);
hello.show();
return a.exec();
}
编译过程:
# qmake -project
# qmake
# make
前两步都没问题,当执行make时出险错误,如下:
