我已经使用QT的安装程序(在线版本1)在Ubuntu 16.04中安装了QT 5.8，安装完成后，我尝试使用MainWindow的基本代码创建一个GUI应用程序，该代码将您作为起点，但无法编译。
我在Windows 10和Zorin OS(基于Ubuntu的发行版)的另一台计算机上完成了完全相同的操作，并且运行完美。
尝试编译时出现以下错误:

我试图找到一种可以在Internet上找到解决方案的方法，但我无法弄清楚。
任何帮助，将不胜感激。
最佳答案
您的C++标准库 header utility似乎已损坏:
/usr/include/c++/5/utility:213:5: error: ‘qtruct’ does not name a type
qtruct _Build_index_tuple
我会尝试在该文件中将
qtruct更改为struct。或者您可以重新安装标准库
