Bool Boolean error

Using Arduino Programming Questions

Hey, I'm new to this whole Arduino stuff and I keep getting this error when trying to compile my code.
Could any of you explain what this means and what I should do to fix it?

Arduino: 1.6.5 (Windows 7), Board: "Arduino Uno"

In file included from sketch_aug23a.ino:11:0:
C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino/Arduino.h:117:14: error: conflicting
declaration 'typedef bool boolean'
typedef bool boolean;
^
In file included from sketch_aug23a.ino:2:0:
C:\Program Files (x86)\Arduino\libraries\DateTime/DateTime.h:17:17: error: 'boolean' has a previous
declaration as 'typedef uint8_t boolean'
typedef uint8_t boolean;
^
Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

Sorry if this post is in the wrong place, I'm new here, I'm still learning

I'm not sure how to fix that, but you're using two libraries with different definitions of "boolean" and that's a conflict. It's not going to work because the complier doesn't know which one to use.

The Arduino.h definition as a C++ type bool is standard for Arduino, so you might need to find a different time library.

But, the program may need to be re-written to use the new time library.
