Teleop_panel standalone

[tonaaskarwur]

I am trying to develop a GUI for AGV robots. For the teleop mode, I wanted to add a teleop_panel for it. After seeing the original tutorial, I am still confused on how to build the teleop_gui as a standalone ros pkg (since it is docked with rviz). So far, I managed to build it but it is not running (error: Segmentation fault (core dumped)). It's been difficult for me to find a reference of gui_teleop panel that is separated from rviz. Do you have any ideas or suggestions? thank you
I am using Qt and C++ with catkin_make to build my GUI project.
