Failed to compile file code.cpp arduino build failed

Hey everyone,

I am actually trying to upload a very simple program in my brother’s mBot with the mBlock v5.0.0 while it is USB plugged. When I try to upload it, it always gives me back that error.

The error says “millis” was not declared…
Would you post your program?

We are getting exactly the same error. Our program is really simple, and there is no mention of ‘millis’ in it anywhere….

Wait - my 9-year-old son just found the bug in my code:joy:
He replaced the first block (on green flag…) with a when mcore starts up
and now it work!

awesome:grin:

Hi folks,

I’ve hit the same issue. No matter what kind of program I’m trying to build.

Using Ubuntu 16.04, Chrome + makeblock web IDE, mBot device

Looks like your Docker container need a proper libraries setup:

mBlock 3 and 5 web version worked with mBot. Would you take some screen shots of your error page, as well as your program.

lifdmitry · 2018-12-10 05:18:06 UTC

Hi,

I’ve figured out the issue. A program must have a proper start block (event - “when mbot initialized”).
Then it works. Looking for comprehensive documentation for mBlock5.

Dmitry

tech_support · 2018-12-10 07:01:34 UTC

Once we selected the mode: upload mode or online mode, the correct start block will be available, while other blocks are grey out.
As for the documentation for mBlock 5, thanks for your suggestion. And we are trying to write a comprehensive guide book for mBlock 5.
