Danois90:
So.. Still no help to solve this.. I've tried to install Arduino from rIs it possible to let the new version of Arduino (1.6.14 with avr-g++ version 4.9.2) use the old compiler somehow?
This will give you Arduino IDE 1.6.14 with avr-gcc 4.8.1:
- Tools > Board > Boards Manager...
- Wait for downloads to complete.
- Click on "Arduino AVR Boards".
- Select 1.6.9 from the "Select version" drop down menu.
- Click "Install".
- Wait for installation to complete.
- Click "Close".
