I'm getting the following error when attempting to verify the Blink sketch from the Basic examples Arduino provides. No changes to the code at all.
In file included from /home/ubuntu/opt/tools/arm-none-eabi-gcc/7-2017q4/arm-none-eabi/include/stdlib.h:11:0,
/home/ubuntu/opt/tools/arm-none-eabi-gcc/7-2017q4/arm-none-eabi/include/stdlib.h:225:8: note: previous declaration 'char* utoa(unsigned int, char*, int)'
char * _EXFUN(utoa,(unsigned, char *, int));
exit status 1
I've tried uninstalling and reinstalling the plugin for the Web Editor.
I've tried both the ports on the Due and I get the same error with both. I also get the same error when trying to verify the 'Bare Minimum' sketch via Arduino.
At one point I was able to use the Web Editor to run complex sketches on this same Due, but after attempting to get it to work with the Desktop version of the Editor, failing, then trying to just use the Web Editor again, this error started occurring.
I've spent a fair amount of time googling the error and haven't found a fix.
I've checked driver issues, updating board, etc... Nothing.
The error occurs with every sketch I try.
I also am getting this error which seems to be related. Sometimes I get the one above, sometimes I get the one below:
arm-none-eabi-gcc: error: unrecognized debug output level 'cc'
exit status 1
