Error when installing ROS Kinetic on Raspberry Pi 4 Buster

edit

Hello,

I am trying to follow the instructions when installing ROS onto my Raspberry Pi 4. I have done this before with the Pi3 multiple times and am following the directions verbatim. When I get to building my Catkin Workspace I follow the directions for Buster and when I go to build it I get an error saying

/home/pi/ros_catkin_ws/src/opencv3/modules/python/src2/cv2.cpp: In function ‘bool pyopencv_to(PyObject*, T&, const char*) [with T = cv::String; PyObject = _object]’:
/home/pi/ros_catkin_ws/src/opencv3/modules/python/src2/cv2.cpp:885:34: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive]
     char* str = PyString_AsString(obj);
                                  ^

If someone could please help me with fixing this issue that would be great.

Thanks.
