After the updated of last night I opened up the shiny new xcode 3.2.3 and tried to build TT. I got the following errors

“___save_vfp_d8_d15_regs”, referenced from:
…..
“___restore_vfp_d8_d15_regs”, referenced from:

Turns out this is to do with the new settings that are used for targeting certain OSs. The answer was on this page.

“You are building against ARM7 and it’s not allowed when targeting iOS4 and base sdk is os3.

Go to your project settings and make sure “Build Active Architecture Only” is selected. Then on active Architecture choose Arm 6 and it
will all be fine”

I did, and it was. Nice to have what looks like a scary problem fixed so easily. Google rocks.
