the first thing I tried was setting the parameter [Mach-O Type] to *Dynamic Library*, but then QuarkXPress 7.31 crashes on startup.
I always felt to be on the right side supposing that a QuarkXPress XTension has to be a *Bundle*, and not a *Dynamic Library* (or am I wrong?). In my project settings there hasn't ever been any Mach-O Type set EXPLICITLY to any of the selectable types, but it always worked. It's important to notice that the use of exactly the same project file(s) for both versions of Xcode, linking has never been a problem to v2.4.1 but only to v3.0.
I hope that the following details can help to bring some light into the dark.
Thanks in advance,
Martin
P.S.: My last message was possibly too large and might have been lost because I attached the rather verbose QuarkXPress crash log.
