    I don’t seem to get the Controllino Board support working on Arduino IDE Beta 2 Beta 3.

    If I include <Controllino.h> I immediatelly get a compile error

    Compilation error: Error: 2 UNKNOWN: exit status 1

    Anybody got it working?

    The problem was “between keyboard and chair” 😉

    I forgot to install “Controllino” Libs, not just the board – silly me.

    Now I’ve got the following installed:

    • Boards: Arduino AVR Boards (1.8.3), Controllino (3.1.0)
    • Libs: Controllino (3.0.5)

    But now I do get the following error:

    Compilation error: Error: 2 UNKNOWN: exec: "/bin/avr-g++": file does not exist

    The compiler seems to live in the following directory:


    Which files to patch so I can get it to use this path?

    I have tried to test the Arduino 2 Beta 3 IDE and it seems to be full of various bugs. Finally I have reached more or less the same state like you, but with more details, as I have used the verbose compilation output. May I ask you to try it again with the verbose compiler and share the result with us? And in addition – which CONTROLLINO variant do you have? And do you have installed also some old Arduino IDE (as you can see I have Arduino 1.8.3)?

    Using board 'controllino_maxi' from platform in folder: C:\Users\Lukas\AppData\Local\Arduino15\packages\CONTROLLINO_Boards\hardware\avr\3.0.2

    Using core 'arduino' from platform in folder: C:\Users\Lukas\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.3

      I already thought that having both versiones installed could lead to problems and therefore I uninstalled all versions first and cleaned the “%localappdata” and “Documents/arduino” from all what remained from Arduino.

      Then and I reinstalled the Arduino 2 Beta 3 IDE again.

      At the moment I’ve given up, cleaned the system again and reinstalled the old version 1.8.3.

      There’s real work to be done right now.

      Can send you a photo of the setup in PM, if you’re interested.
