I’ve been working on an app on my PowerBook GeeFour for a while now and it builds and runs fine.
This morning I tried to copy the project onto my work machine, a GeeFour tower. When I try to build it I get a cascade of errors (2128 total), begining with:
“Precompiled header is invalid; header file /System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h is now different.”
Both machines are running OS X 10.2.6. What do I need to do?
When I try to compile my project, I get exactly 2128 errors. And you can see a screenshot here :

I don’t know what to do. The only advice I don’t want to read is : “Buy Panther”. Remember that I’m poor and can’t afford it… yet…
Delete the build folder and recompile.
I’d just like to add my heartfelt thanks for the suggestion above. After working on a project for some days, I found suddenly that I could no longer build it- the compile would hang up half way through, with whirling coloured cursor. The only way out of this was to force-quit Project Builder.
I deleted the build folder as recommended above, and that fixed the problem. Thank you!
