when I had compiled, last line is erroring. It said, 'class CAN_MCP2515' has no member named 'getCanId'. But I had added libraries. Can you help me?

What board or board/shield are you using? Doesn't the MCP2515 have it's own library?

I using Niren MCP2515 CAN shield. It has not library. I just found to libraries in internet. But When I compiled the library examples, I am getting error again.

Have a look here, seems to be some good information.
