oled display problems.

I am trying to get an Oled 128X64 display to work from a uno. using the 4 wire spi.
I have downloaded the recommended library an examples.
Library = <Adafruit_SH1106.h>
I am attempting to run the example downloaded with the library. SH1106_128X64_spi

When I attempt to compile I get an error.

Any ideas most help full.

Which OLED do you have?
Can you link to the item?
