Dear David,
Thanks for trying to help, I kept getting the same error when trying to compile example code from the ssd1306 example list. Indepently from what Board I've selected I kept getting the same error. I also run the same example sketch like you.
After re-installing all libraries it worked!
I had to change the .h file to select the screen i use (e.g. 128/64 instead of the selected 128/32
Thanks a lot!
For completition:
The previous post where I read something on the internet: I was referring to this (the only OLED SAMD21 post i could find on arduino.cc)
Perhaps I misunderstood the post:

Also I am unable to confirm what SPI and Wire version I am currently running.
But it runs now!
Thank you David!
