请问这是什么错误呀？怎么解决？

光看这个，不好回答。

从错误提示上，对比你的源码应该可以找到问题所在。

断点调试不行吗

哦。。谢谢。。
源码很简单。就是书上的hello world那个例子

#include <QApplication>
#include <QLabel>
int main(int argc,char *argv[])
{
QApplication app(argc,argv);
QLabel *label = new QLabel("hello qt");
label -> show();
return app.exec();
}

为啥我在机器上就能运行？？ .pro文件要写对  你qmake的时候一定要把路径弄清楚  否则会出错的

main.c.......................
main.cpp吧 。。。。

呀。。就是。用C用习惯了。刚开始用C++。不好意思哈。。现在好了。。多谢啦。。
