I'm trying to follow this this tutorial to program an ATtiny85 micro-controller using my Arduino Uno r3 as the ISP.

I am up to the final step on the tutorial, but get an error when attempting to compile my sketch:

'OUTPUT' was not declared in this scope

I have tried multiple "Blink" scripts, but none have seemed to work.

My full error log:

Blink.ino:10:21: error: Arduino.h: No such file or directory
Blink.ino: In function 'void setup()':
Blink:15: error: 'OUTPUT' was not declared in this scope
Blink:15: error: 'pinMode' was not declared in this scope
Blink.ino: In function 'void loop()':
Blink:20: error: 'HIGH' was not declared in this scope
Blink:20: error: 'digitalWrite' was not declared in this scope
Blink:21: error: 'delay' was not declared in this scope
Blink:22: error: 'LOW' was not declared in this scope

I have also tried including Arduino.h, no help, and changing "OUTPUT" to "0x01", as it is defined to said value in Arduino.h, but instead got this error:

error: 'pinMode' was not declared in this scope

Any ideas as to what is happening?

    If you change the board back to Arduino UNO does it compile? Could you turn on verbose mode for compilation and post the text that appears when you compile. – geometrikal Aug 6 '14 at 12:02

    It looks like the Arduino core libraries aren't being included... – Anonymous Penguin Aug 6 '14 at 13:05

    Are you using the latest version of the Arduino IDE? Seems similar to (this problem](forum.arduino.cc/index.php?topic=82220.0), but in reverse. – Gerben Aug 6 '14 at 14:52
  • The first issue, the 'missing' .h file, creates the others. Fix the INCLUDE path and the other errors will go away. – JRobert Jan 11 '15 at 15:36

Create an Arduino.h in ...\Arduino\hardware\attiny45_85\cores\attiny45_85 containing

#include <WProgram.h>

Try moving the "Cores" folder from the avi directory to the attiny director. The path was wrong for me and I was getting the same error. Had the same issue with the bootloader file. Moved it out of the avi folder as well and all worked ok then.
