Hi everyone.
I try to shrink an Arduino sketch to an ATTtiny 85 and have tried to go through all the steps to installation the device (went ok, the Atttiny appears in the ide board supported list), then tried to install the Bootloader and then it fails: here are the messages I get:

Obviously something does not work.
The previous steps are indeed followed s requested.

What does this mean? Who's requested something?
What are all the steps you are doing from the very beginning? Include all the wiring, sketch loaded to the Uno, menu selections made as you go through the steps, etc. Everything step by step. Perhaps you are skipping a step.
the ATTiny appears in the list of boards and is ticked OK
the Atttiny parameters are properly set
I have 'Arduino as an ISP' ticked. Here, I still am not sure wether I should run the ArduinoISP sketch before trying to upload, or not. I tried to compile it and it sends loads of compiling error messages ! So if I should run it it would just fail. So I now am just keeping it as a parameter on the Tools list.
I I try burning the Bootloader I get the messages above, it seems the avrduderc file is somehow not good ? this is a configuration file, would it mean the downloaded file for ATTTiny85 are wrong or incomplete ? Don't know.
Thanks for your help.
Could it be because I run all this Arduino 1.6 from an 2009 iMac and not a recent Windows system ?
You're supposed to upload the ArduinoISP sketch to the Uno. The reason for the compiling error messages is that you are trying to compile it for the ATtiny85. Please read https://www.arduino.cc/en/Tutorial/ArduinoISP.
Works !
First I had to update my AVR library, I was running on old refs.
Then I had to run the ArduinoISP on the UNO board with its UNO settings; then change the settings to ATtiny ones and then burn successfully the Bootloader and so on.
Two steps .
