Hi @ChipLeo. It will be helpful if you provide some additional information:

When you encounter an error you'll see a button on the right side of the orange bar in the Arduino IDE "Copy error messages" (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). Click that button.

Paste the error in a message here using code fencing.

You didn't post the important information of which board you are compiling for. I'm guessing it's one of the AVR boards.

@ChipLeo you might want to take a look at https://github.com/autowp/arduino-mcp2515 ... it is an excellent library and should be available for AVR.
