I have been trying to get this example (and others like it) to work on a Mac OS X host.

On my setup, the Arduino shows up at /dev/cu.usbmodem144421
but running
docker run --rm -it -v "$(pwd):/src" --device=/dev/cu.usbmodem144421 strm/dev-arduino serial
(slight modification of what is in functions.sh, which assumes /dev/ttyUSB0), produces the error:

docker: Error response from daemon: linux runtime spec devices: error gathering device information while adding custom device "/dev/tty.usbmodem144421": no such file or directory.

Is device mapping fundamentally different from a Mac OS host, or am I missing something?

Hi @opsxcq!

my goal is to build the firmware in the ci pipeline. My sketch for an ESP8266 uses libraries.
Could you please add an example how, to add libraries and set the board correctly?

I have found two files:

/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/boards.txt
/Applications/Arduino.app/Contents/Java/lib/version.txt

kind regards, André
