Hi. I've just read TN2064, http://developer.apple.com/technotes/tn2002/tn2064.html . I'd like to set up weak-linking in my app, but I'm not clear on where to set some of the variables.

I have my Carbon app project, and it links against another project (a C++ application framework) that produces a statically-linked library. Both projects share a single .xcconfig file.

Can set things in the .xcconfig like MAC_OS_X_VERSION_MIN_REQUIRED? Does Xcode automatically define build settings in as preprocessor macros in the source, too?

Really I'm asking, how do I configure my Xcode project(s) to weak- link 10.5 APIs and hard-link 10.4 and earlier?

I think I've found the answer to this in the cross-compiling guide.
