This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.
You'll need to find typedef unsigned char boolean; in your library and change it to match the version in Arduino.h.
boolean is already a typedef in Arduino.h, and it is a bool ,not unsigned char .
In the AX12 library search for this: https://github.com/7Robot/Arduino/blob/master/AX12/libraries/ax12/ax12.h#L66
And change it to typedef bool boolean; .
This was updated a while ago, so your IDE version is newer than the AX12 library.
