I am getting the following error message when compiling a program on my Arduino IDE. This does not happen when compiling the given example programs in the IDE.

The error message is as follows :

This is a known incompatibility between the Arduino IDE and Microsoft OneDrive. A fix should be available soon; in the meantime, move your Arduino sketches out of the OneDrive folder.


Following on from duskwuff's answer, the issue with OneDrive folders has been resolved as of version 1.8.6.


ARDUINO 1.8.6 2018.08.23


  • Updated arduino-builder to 1.4.0:
    • parallel build (improve compile speed)
    • better reuse of already compiled files
    • Windows: fixed build for sketch stored under OneDrive cloud folders

Simply update to a newer version of the Arduino IDE and you will be able to compile and upload your sketch.
