Hi All,

I am new to ROS. I am using Ubuntu 20.04, ROS Neotic Ninjemys in VMware workstation. I am simply following a course in motion planning. just get started. And what i am asked to do:

Copy 3 folders (from course) to catkin_ws - src, one called 'grid_path_searcher', one called 'rviz_plugins', and the other one called 'waypoint_generator'

Delete Build and devel folder under catkin_ws, delete CmakeList.txt under catkin_ws - src

and then open up the terminal, enter the following code:

ls  'to see catkin_ws''
cd catkin_ws/ 'to enter it'
ls
cd src/ 'to enter it'
catkin_init_workspace     'to initialize it'
cd ..    'go back to previous folder'
catkin_make

then there are huge amount of codes jumped in my screen and I can barely copy all of them here. and the first few rows of code can not be scrolled up. looks like they terminal can only display certain amount of codes. So I just picked up all the error messges here for your reference.
