Your LVGL version is outdated.

Your LVGL version is outdated.

Yes, but unfortunately with platformIO there is still no update available for the lvgl library. So 8.0.1 is the latest I can add to the project. See screenshot below.

@kisvegabor might need to publish it manually: https://github.com/lvgl/lvgl/issues/2315#issuecomment-866099381

Thank you very much, I could update and compile it now without errors.
