Libuavcan interfacing with chibios

Hi,

I’m trying to interface libuavcan with chibios. I’ve made changes to main make file by comparing with libuavcan\libuavcan_drivers\stm32\test_stm32f107\Makefile. But I’m getting below error which i’m unable to resolve.
I’m new to uavcan, chibios and c++ as well. Please help me to resolve this problem.

You are trying to include a C++ header file into a C file, this is not permitted, so don’t do that.

Also, UAVCAN has ceased to exist. There are two successor projects: DroneCAN for legacy systems, Cyphal for modern systems. More info:

Thankyou @pavel.kirienko.

Yes I’ve included header files in main.c file. And renaming it to main.cpp worked.

Yes I’ll note that and switch to DroneCAN.

Thankyou for your time:)
