Question [Q] "Cannot find symbol" error while compiling an AOSPA build


I'm trying to compile Paranoid Android for my Nexus 4 and I got stuck on the same error that I can't find how to solve...
Maybe someone knows what the kind of message I get means, here is the end of my last attempt, it's about variables missing in the file "" or something like that :

Thanks, some help would me very much appreciated!
