I am trying to use Arduino (Uno and Mega 2560) with LabVIEW Interface for Arduino.
For that, I need to upload the LIFA_Base program to the Arduino board. Simple thing to do, and
it worked yesterday, and I could control the blinking of the LED on Arduino boards via LabVIEW.
But today I cannot compile the LIFA-Base.ino file on either board (Uno, Mega). My Arduino IDE 1.8.2 stops compilation with this message:
C:\Users\GUSARW\Documents\Arduino\libraries\LiquidCrystal\I2CIO.cpp:35:26: fatal error: ../Wire/Wire.h: No such file or directory
#include <../Wire/Wire.h>
^
compilation terminated.
Multiple libraries were found for "LiquidCrystal.h"
Used: C:\Users\GUSARW\Documents\Arduino\libraries\LiquidCrystal
Not used: C:\Program Files (x86)\Arduino\libraries\LiquidCrystal
exit status 1
Error compiling for board Arduino/Genuino Uno.
Reinstalling IDE doesn't help.
I also tried to comment out these lines in the (attached) file: #include <Wire.h> #include <SPI.h> #include <Servo.h>
The error message didn't change.
I don't completely understand the error message and what is causing it.
Please help.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
because I do not have LabVIEWInterface.h.
Same result if I uncomment your 3 other #includes. Seems to be a problem with your installed IDE. Try reinstalling it.
Solved!
Arduino IDE just randomly notified me that a few library updates were available.
One of them was for LiquidCrystal. I updated the LiquidCrystal library, and the error disappeared.
How this library got "outdated" overnight and caused the error is a mystery to me. I didn't touch the Arduino IDE since it was working fine yesterday. Maybe my manipulations within LabVIEW somehow affected it?
