I'm using the Cocoa class QCRenderer after testing for Tiger or
later. This means I have to link to Quartz.framework which I do as a
weak link so I can still start under Panther and test the system
version before trying to instantiate QCRenderer. This worked fine
when building on Tiger.
Unfortunately I've found that when building on Leopard all I have to
do to crash Cocoa on Panther is add "-weak_framework Quartz" to
Xcode's "Other Linker Flags". It's not even necessary to add
Quartz.framework to my project. When this linker flag is added the
following code will crash on Panther on the second line, although it
seems just about any reference into Cocoa will crash (e.g., @try will
do it).
NSApplicationLoad();
[NSAutoreleasePool alloc];
Therefore I can't link or weak link my application to
Quartz.framework. Is there any way to instantiate QCRenderer without
doing that?
I guess I could create a private framework to instantiate QCRenderer
and only load it on Tiger and later, but it seems like there ought to
be an easier way in Obj-C.
Thanks
Nick Nallick
