我已经使用QT的安装程序（在线版）在Ubuntu 16.04中安装了QT 5.8，并且一旦安装，我尝试使用MainWindow的基本代码创建一个GUI应用程序，它将它作为一个起点，但它没有＆ ＃39; t compile。
我在Windows 10和Zorin OS（基于Ubuntu的发行版）的另一台机器上做了完全相同的事情，它运行得很好。
尝试编译时，我收到以下错误：

我试图在互联网上寻找解决方案，但我无法弄明白。
任何帮助将不胜感激。

看起来您的C ++标准库标头utility已损坏：
/usr/include/c++/5/utility:213:5: error: ‘qtruct’ does not name a type
qtruct _Build_index_tuple
我尝试将qtruct更改为该文件中的struct。或者您可以重新安装标准库
