Could you give the *exact* error message? BTW, this is something you 
should always do if you want people to be able to help you ;-)

My guess at this point would be that the undefined reference is not your 
'hello' function but 'printf'...

The function declaration is not the problem here. If it was, the 
compiler would give you an error along the lines of "'hello' was not 
declared in this scope".
