ChibiOS Free Embedded RTOS

Hi guys.
I'm a few days trying to compile examples of ChibiOS to ATMEGA328P (Arduino) and I can not.

I searched this forum, searched the web, searched the documentation, but all I got was getting more confused.

Does anyone know why these errors?

Hi,

You must use GCC not G++.

Hello Giovanni.

I tried to change the compiler, but failed.
My problem was with the paths.

Thanks for the help and sorry for the delay to thank.
