107-Arduino-MCP2515 library on Mega: functional: No such file or directory

bulek · January 22, 2021, 9:07am

Hello,

I'm new in Arduino world. I'm trying to implement CANbus sniffer.
There are a lot of projects and libraries available - hard to choose.
What is you recommendation ?
ca
For a start, I've chosen 107-Arduino-MCP2515 library installed from inside IDE.
I've taken CANBus sniffer example project and I'm trying to compile it for Mega.
I get following error (highlight and full log output below).

Any advice, help ?

Thanks in advance,
regards bulek.

fatal error: functional: No such file or directory

 #include <functional>

Hi @bulek. As explained here by the library author:

github.com/107-systems/107-Arduino-MCP2515

Restrict list of supported architectures to samd

107-systems:master ← 107-systems:only-samd-arch

+1 -1

Since `107-Arduino-MCP2515` uses advanced C++ features such as `<functional>` it… can not be compiled for AVR boards. Therefore it is a good idea to specify the supported architectures which is currently `samd` only. This PR fixes #10 since it gives users a warning when compiling for a different architecture then samd.

Since 107-Arduino-MCP2515 uses advanced C++ features such as it can not be compiled for AVR boards.

The Arduino Mega board you are using is AVR architecture and so is incompatible with this library.

The library author has suggested an alternative library which is compatible with your Mega:

you might want to take a look at GitHub - autowp/arduino-mcp2515: Arduino MCP2515 CAN interface library ... it is an excellent library and should be available for AVR.
