Can anyone explain why I get:
o: In function main': undefined reference to setup
when I try to upload the firmata software to the nano? I've tried it on several macs with different OS, but same thing. Any ideas, anyone?

Hi,
what do you mean by "upload firmata software"?
I suggest you try to upload one of the Firmata-Examples Menu->File->Examples->Firmata->...
I guess you get the compiler error because you forgot to define the setup() function in your main sketch?.
It's enough to have an empty (do-nothing) setup-function, but it must be defined!
