For a long time I've avoided the problem of OS back-compatibility
by releasing a CFM-only version of my program. I'd like to include
both a CFM and a Mach-o binary in the package for full
compatibility, but I am having limited success
I'm developing under Tiger, and I've set the target SDK version to
10.1.5 and deployment target to 10.1. When I do this, I get the
following link errors:
See http://developer.apple.com/documentation/DeveloperTools/
Conceptual/cross_development/HowItWorks/chapter_2_section_9.html,
"Limitations." Weak-linking was not impmented in 10.1. So while you
can use the SDK to cross-develop to 10.1 exclusively, you can't cross-
develop for a range of OS versions that includes 10.1.
Thanks Chris. So there is no way of arranging for the CFM version to
launch on 10.1.5 then, when the mach-o version (built for 10.2 and
later) fails to launch? I guess I'll have to distribute that as a
separate bundle...
