Online compiler not working

Hi Guys,

Since yesterday, I got an error on every compile attempt I do in the online create tool. I got it on both my home and work computer and if I try the same sketch in the offline IDE, I have nog problem. I first tought there was some sort of problem with the server (because I use windows and those paths are clearly comming from a unix system), but how is it that I don't read any other massages about this issue? Can I do something about this?

lto1: fatal error: bytecode stream generated with LTO version 3.0 instead of the expected 4.1

compilation terminated.

lto-wrapper: fatal error: ./opt/tools/avr-gcc/5.4.0-atmel3.6.1-arduino2/bin/avr-gcc returned 1 exit status

compilation terminated.

/home/ubuntu/opt/tools/avr-gcc/5.4.0-atmel3.6.1-arduino2/bin/../lib/gcc/avr/5.4.0/../../../../avr/bin/ld: error: lto-wrapper failed

collect2: error: ld returned 1 exit status

exit status 1

Thanks for the support!

There are multiple other reports of this bug:

I recommend subscribing to those threads so that you'll be sure to get news of any progress in fixing it.

This is an Arduino Web Editor specific problem so the workaround is to use the regular Arduino IDE, which you can download for free from:

Considering this is at least the 18th post about it today, probably because you didn't search?

FYI, there is a forum section specifically for the Arduino Web Editor, where the people who can help with this sort of web editor-specific problem are most likely to see your post:

Hello, please follow topic Issue 2018-10-30: lto-wrapper error prevent compilations for further information and updates about this.

Thank you.
