a blink sketch to a attiny-- problem

i have mounted a attiny45 in my sparkfun avr isp shield which i successfully use with a UNO below as an ISP to load a bootloader onto other 328s with no problems .
so i now try to load a sketch onto the attiny45 ,just a simple blink sketch ,modfying the pin 13 to pin 0 for the blink sketch .but i keep getting the error message 'OUTPUT' was not declared in this scope .
why cant i get this to compile ?
the attiny is a 8 pin device .

Why can't you get what to compile?

i cant verify the blink sketch .

We're a bit detail-deficient here.

From the few details, i guess yor Tiny-core isn't installed right

Try this core

Follow theese instructions
