Compilation Error:

The latest cli (0.3.2) fails to compile anything, giving the error:

$ arduino-cli compile -b arduino:avr:uno rfid_unlock/rfid_unlock.ino

Do you also have the Arduino IDE installed on the system?

I'm getting the same thing with 0.3.3 on a mac with the IDE installed. This is trying to install the blink sketch from a non-default location:

You're calling the command wrong. This is what works for me. (My makefile):

BOARD := "arduino:avr:uno"
PORT := "/dev/tty.wchusbserial1430"

.PHONY: compile

compile: rfid_unlock.ino
	arduino-cli compile --fqbn $(BOARD) .

.PHONY: upload

upload:
	test -e $(PORT) || { echo "Port not found!"; exit 1; }
	$(MAKE) compile

	arduino-cli upload  --fqbn $(BOARD) -p $(PORT) .

.PHONY: clean

clean:
	rm -rf build/*
	rm -f *.hex *.elf

Just give it the directory and it'll find the sketch.

Thanks! I'll try again.

I'm calling it from PHP like this:

shell_exec('./arduino-cli compile --fqbn arduino:avr:nano ' . $path . ' -v > "./uploadoutput.txt"; ./arduino-cli upload -p ' . $port . ' --fqbn arduino:avr:nano:cpu=atmega328old ' . $path . ' -t -v');

The arduino-cli file is in a random folder. Beneath it is a folder called "code" that holds the Arduino folder and file.

update: the same code works when placed on a headless Raspberry Pi which does not have the IDE.
