Warning: Board breadboard:avr:atmega328bb doesn't define a 'build.board' prefere

In next days I will try the ATMEGA standalone with internal 8MHZ.

I did download the "hardware breadboard" sketches and I did insert in documents folder (Arduino IDE did recognize them).

But at the moment I'm deloping with the Arduino directly.

Everytime I compile a sketch, it functions very well but I have this warning in bottom output:

"Warning: Board breadboard:avr:atmega328bb doesn't define a 'build.board' preference. Auto-set to: AVR_ATMEGA328BB"

Do you have some idea? Thank you very much!

I did try last (1.6.13), the previous (1.6.12), same warning.

I did try the 1.6.0 and won't compile the RF24 library.

Now downloading the 1.6.5.

Do you have some hint on which version? If I try to load a bootloader and sketch, there will be error or is it only a warning?

(with Arduino UNO no problem with loading sketchs).

Thank you

It's only a warning. It won't cause any problems at all. Just ignore it. If you need to use the board identifier macro it will be ARDUINO_AVR_ATMEGA328BB, that's all the warning is telling you. Please continue to use the latest version of the Arduino IDE. You definitely don't want to use 1.6.0.

Just what I needed! Kudos!
