Unknown compilation errors with Arduino IDE version 1.8.10 | FAQ (Frequently Asked Questions) | Forum

Version 1.8.10 of the Arduino IDE outputs unexpected DEBUG messages which causes an issue with the compilation result of the Arduino Compatible Compiler for LabVIEW.  This is a documented issue here:

https://github.com/microsoft/v.....issues/891

There are two solutions:

1) In the link above, there is a solution to remove the DEBUG messages as follows:

The excessive debug logging is caused by running Java with -DDEBUG=true. Adding -DDEBUG=false to the C:\Program Files (x86)\Arduino\arduino_debug.l4j.ini fixes it.

2) Revert to an older version of the IDE.  The last Arduino IDE version that has been formally verified for use with the Arduino Compatible Compiler for LabVIEW is 1.6.6.
