Apple Mach-o Linker (id) error, undefined symbols for architecture i386:

I don't know much about coding but I have an app in the appstore and for some reason when I build now in the simulator I get 53 of these apple mach-o linker errors and nothing in the code has changed. I reinstalled xcode 4.0 and sdk 4.3. i've switched to different compiler versions (gcc and llvc gcc) still get the same 53 errors. I've turned symbols hidden by default on and off, i've toggled ton's of things but always the same 53 errors. I was wondering if anyone could give me some insight on how to fix this or why it randomly happened, the builds were perfect two nights ago. Thanks.
