[avr-gcc-list] Fwd: [Tinyos-help] TinyOs avr-gcc-4

[David Gay]

Seems some other people than Domenico (who asked, and got an answer,
this question earlier) would be interested in this... (also, though
the e-mail isn't 100% clear on that subject, the instructions are for
using avr-gcc+binutils as is, i.e., w/o the patch to support $ in
identifiers).

You need nesC 1.2.9. I think there's no rpm at this point, so you'll
have to install it from source, available at
http://sourceforge.net/project/showfiles.php?group_id=56288
Read the INSTALL directions once you've extracted files from the tarball.

You will also have to make the following changes to the tinyos tree
(changes to the avr make rules):
