Issue with QVTKWidget in QT Ros workspace
-
I am new to QT and ROS. I am working on QT Creator 4.8.0. I have created a catkin workspace in QT and a mainwindow was created. And I am trying to add QVTKWidget to the mainwindow. It was successfully built but when it is run, an error message is displayed.
Code: mainwindow.cpp
vtkWidget = new QVTKWidget; // When this line of code is executed, runtime error occurs.
ui.verticalLayout->addWidget(vtkWidget);
ui.verticalLayout->update();
ren = vtkRenderer::New();
vtkWidget->GetRenderWindow()->AddRenderer(ren);
ren->SetBackground(1.0,0,0);
ren->Render();Error:realloc(): invalid pointer: 0x00007facb5723820 ***

Actually I didn't build VTK. It was already there. So I assume it came with the QT installed.
As you have suggested , by running the command ldd applicationName I got the following libraries:
