Nios2ide 10.0 Unresolved inclusion

Hi all

Nios2ide 10.0 complains about unresolved inclusion for # include <stdbool.h> # include <stdlib.h>

These two# include are in a Nios II Library that I have added to the project.

Do I need to add a include path in the libraries properties? If so, which path?

Thanks in advance,
