Question

qt编写程序执行make时出现错误

qmake -project和qmake helloqt.pro都没有问题
就是一个最基本的helloqt的显示框，结果make的时候就报错，不知道为什么，源码：
#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();
}

编译信息

Answer 1

环境变量没有配好吧。

Answer 2

错误信息里有很多undefined reference to，并且是qt自带的头文件里的，应该是qt没装好，重装qt吧，全部组件都安装，除非你有把握不装不会出错。
