troubleshooting Marlin compile error

Raspberry PI 4, PandaPi 2.0, latest img and after doing a Raspian update.

I do not have a heated bed at the moment. TEMP_SENSOR_BED set to 0.

Here's the output from running make on an SSH session in /home/pi/PandaPi/Marlin2.x/pandapi:

pi@octopi:~/PandaPI/Marlin2.x/pandapi $ make
