I've rebuilt my app as a universal binary and nailed all the endian
problems so it works like a champ on both Intel and PPC on 10.4.
However, when I try to run it on 10.3.9 I get:
dyld: AppName.app/Contents/MacOS/AppName Undefined symbols:
AppName.app/Contents/MacOS/AppName undefined reference
to .objc_class_name_NSAffineTransform expected to be defined in
Foundation
Just NSAffineTransform, nothing else. If I comment out the code
that references it the application runs just fine (the
NSAffineTranform piece is a tiny percentage of the total application
so the remainder isn't trivial).
Since after much searching I can't find anyone else with a similar
problem I'm seeking suggestions of what to look at next.
In Tiger, NSAffineTransform moved from the AppKit into Foundation for
the benefit of some other bits on the system. When you take your 10.4-
developed Universal Binary back to Panther, your binary expects to
find NSAffineTransform in Foundation and it doesn't find it.
If your requirements are such that your application will have to run
back to 10.3 on PowerPC-based Macintoshes, you'll have to build your
PowerPC binary against the 10.3 SDK, the Intel binary against the 10.4
SDK, and then lipo the two halves together.
This is true whether you're using Foundation or not, by the way...
The binary -is- universal. It just depends on how big your universe
is. :) Or at least, how far back in time you wish to go...
