error: 'sendSignal' was not declared in this scope

[oculos]

Hi,

I have a sketch that compiles flawlessly with the Arduino IDE on the GUI of my Udoo. However, when using udoo-arduino-cli, I get this error for function calls:

error: 'sendSignal' was not declared in this scope
sendSignal();

Anything I can do to fix it?

Thanks,

Francis
