Hi Chris what if you're target all of 10.3 -> 10.3.9 but also want
the 10.4 features?
Then you should build against the Mac OS X 10.4 SDK. Building
against an SDK gives you access to the features in that OS release.
The Mac OS X Deployment Target property tells Xcode the earliest
system you want to be able to run on, so it can weak-link features in
the SDK that are not available in your target system.
I thought gcc 4.0 wasn't introduced until 10.3.9.
You can run executables built with GCC 4.0 on Mac OS X 10.3.9. If
you need to support earlier releases of Mac OS X, you need to use GCC
3.3.
Up until now I've had the Mac OS X Deployment Target to 10.4u, with
Edit Active Target > Rules > Rules Specific to Target and setting
it to gcc 3.3 for the C, C++ and Assembler settings. Will this let
me support 10.3 -> 10.4 inclusively? I don't have a 10.3 machine
anymore, so I simply can't tell.
For what it sounds like you want to do, you should build against the
Mac OS X 10.4 SDK, specify a Mac OS X Deployment Target of 10.3, and
specify GCC 3.3 as your compiler.
