[Tinyos-help] avr-gcc on Mac -- not only for Mac users

[Paul Stickney]

Those error messages seem to indicate the standard C library headers
can't be found.
Ensure C_INCLUDE_PATH contains the standard header path and/or use
-I<path_to_standard_headers>
These errors go hand-hand in hand with what you have described about
different target (layout) environments.

That should get you up. Hopefully.

HTH,
Paul
