Fatal compile error on chrome notebook

I'm using the Online editor with Chrome notebook, The code complied ok last friday when I prepped it for my students. I tried it with my student today and got this error. Then tried it on my system and got the same error.

Error output:

Linking everything together...

I am having the same issue as of this morning.

This is what I am seeing.

Same problem in my class too. Really need it fixed for class tomorrow.

According to the team it was fixed.
Thanks for your reports.

Bob.

looks like it is working. Thanks.

yes, fixed . Worked ok with my student yesterday. Thanks Team

I had an error today too, but seems slightly different - i don't see an error, just hanging when trying to upload. It just says "Busy" and progress bar rolls forever.

Here is my log output: flashing-error.log ยท GitHub

I also briefly saw an error message that the compiler wasn't working. But the log seems to indicate that step was OK.

About 30m ago I was able to upload, and then it stopped working. Chromebook, with Arduino Micro - is there still an outage or a bug going on?

Thanks, all!

Could it especially have been the undefined in this line?

Programming with: avrgirl-arduino flash -f undefined -a micro -p /dev/ttyACM0

Moved to Stuck on " connected" possibly due to "avrgirl-arduino flash -f undefined" - Chrome App - Arduino Forum for now!
