Error messages show up after run "make all"
 

Currently I'm trying to make my USB wireless network to work, so I download the atmel driver and when I start to install the Atmel driver by typing
# make config
that went fine and then I run
# make clean
This part is ok too. The probalem is when I run
# make all
It gives me some errors at the end.

Can anyone tell me what are those messages and how can I fix the error problem?
Thanks!
