我的开发环境是QT 5.14.2, PCL 1.9, VTK 8.2.0。

这是我的初始代码：

    // Set up the QVTK window
     vtkSmartPointer<vtkGenericOpenGLRenderWindow> renderWindow = vtkSmartPointer<vtkGenericOpenGLRenderWindow>::New();
     vtkSmartPointer<vtkRenderer> render = vtkSmartPointer<vtkRenderer>::New ();
     viewer.reset (new pcl::visualization::PCLVisualizer (render, renderWindow, "viewer", false));
     ui->qvtkWidget->SetRenderWindow (renderWindow);
     viewer->setupInteractor (ui->qvtkWidget->GetInteractor (), ui->qvtkWidget->GetRenderWindow ());
     ui->qvtkWidget->update ();

当我退出程序时，发生了核心转储，如下所示：

           UID: 1000 (oyoungy)

GNU gdb (GDB) 9.1

我试过 QVTKWidget、QVTKOpenGLWidget 和 QVTKOpenGLNativeWidget，但还是不行。如果我评论代码ui->qvtkWidget->SetRenderWindow (renderWindow);问题不会发生，但我的 pcl 数据也无法显示。

我solved的问题。原来qmake是问题的根源，当我使用qmake构建我的项目时，会发生core dump，但是当我迁移到时cmake，我的问题不再发生，我很乐意解决它，因为我没有退出时需要面对核心转储文件。但是我还是对问题的根源感到疑惑，为什么qmake会出问题呢？这是我的 qmake 版本：

QMake version 3.1
Using Qt version 5.14.2 in /usr/lib
