Error Compiling for Board Arduino Nano

[Curious-Nikhil]

I am running the MPU6050_DMP Example for Arduino Nano.
Processor - ATmega328P (Old Bootloader)

The libs are all up to date.

This error message doesn't make any sense at all.

Hopefully, there's a fix to this.
I'll try some troubleshooting and update this post.

Thanks

Arduino: 1.8.5 (Windows 10), Board: "Arduino Nano, ATmega328P (Old Bootloader)"

We will likely resolve this in Curious-Nikhil's post on the Arduino Forum:

[Curious-Nikhil]

Fix - It was fixed by a simple reinstall of Arduino and libraries.
