Issues building with fresh marlin firmware and PlatformIO 2.2.1

Very interesting. But we should be getting to the bottom of this. Can you please

open the platformio.ini of the Marlin project and after the board line in the mega2560 environment

MarlinFirmware/Marlin/blob/5ee1087959f88dc60386ff3caa21e75d9e20b128/platformio.ini#L431-L438


      
          #
          # ATmega2560
          #
          [env:mega2560]
          platform            = atmelavr
          extends             = common_avr8
          board               = megaatmega2560

add the line

custom_verbose = 1

Then, remove the .pio folder in the project again, build the project and show logs. They should be more verbose now.

Then, please

locate the file buildroot/share/PlatformIO/scripts/common-dependencies.py in the Marlin project
rename that file to common-dependencies-old.py
recreate the file common-dependencies.py and fill the file with the python code found at [BUG] 'CC' is not recognized as an internal or external command · Issue #20671 · MarlinFirmware/Marlin · GitHub
rerun “Build”

It should hopefully start printing PATH: … and give some debug output as to why Marlin thinks that’s the right compiler path.
