Problem building geapp.xcodeproj...

[christhomas]

I am trying to build the geapp.xcodeproj (as the subject suggests). I have successfully added my dat file to to the project and set up a provisioning profile (exactly the way the tutorial showed) and assigned an App ID to my geapp.xcodeproj, but upon building the xcodeproj, I get the following error:

"_main", referenced from:
start in crt1.10.5.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

I am fairly certain that my current target does include start.cpp. Are there any other possibilties? I am running a 64 bit os, might this have anything to do with it? Also, is it possible to use the iphone simulator 3.1.2+ as an SDK instead of the actual iphone device 3.1.2 sdk? I have been trying to solve this problem for a week now and I cannot get rid of this error... I have searched for it on google many times without avail. What are the steps that I need to take to fix this error?
