Command line tool requires X to verify or upload?

[jacobrosenthal]

Trying to docker the arduino command line tools. Most stuff works

[ root@a80a54ab13f1:~ ]$ /usr/local/share/arduino/arduino --get-pref pumpkins                                                             
[ root@a80a54ab13f1:~ ]$ echo $?
4
[ root@a80a54ab13f1:~ ]$ /usr/local/share/arduino/arduino --get-pref board   
uno
[ root@a80a54ab13f1:~ ]$ echo $?
0
[ root@a80a54ab13f1:~ ]$ 

But all verify or upload require X?

[ root@a80a54ab13f1:~ ]$ /usr/local/share/arduino/arduino --upload /root/tester/tester.ino --board arduino:avr:uno --port /dev/tty.usbmodem1411

So was able to use xvfb on Synthbread in irc's advice

Seems like command line tools shouldnt need a gui though :)

Indeed it shouldn't. We'll fix it in one of upcoming releases
