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.

to remove the warning in file hardware\breadboard\avr\boards.txt

add the following line: atmega328bb.build.board=AVR_ATMEGA328BB

Just what I needed! Kudos!
