Hi Michael,
Thanks for your fast anwer and help, it solved the problem I had, but I got new compilation (linking) erros. I put the compilation messages and errors under this message.
avr-gcc is version 4.7.0 so you where right about the problem
Do you have any idea how to solve the new errors?
Thanks,
Mikel
