Why is the linker trying to link in these 10.4 objects when I
explicitly specify I want the
target to run on 10.3?
Well, perhaps you're not building for 10.3? The "Mac OS Deployment
Target" setting should be set to 10.3 if that's what you want.
Alternately, if you're building a Universal Binary, you can specify
per-architecture settings by adding these to the build settings:
MACOSX_DEPLOYMENT_TARGET_i386 10.4
MACOSX_DEPLOYMENT_TARGET_ppc 10.3
I notice it is using the GCC 4.0 compiler. Should I set it up to
build using the earlier
compiler? I remember learning we can change this... how is it
done using 2.1 X-Code?
If you're building for anything earlier than 10.3.9, you need to be
using the gcc 3.3 compiler. You can set this by adding the following
to your build settings:
GCC_VERSION 3.3
Or, again, if you're building Universal, something like this:
GCC_VERSION_ppc 3.3
(Since the default gcc version for Xcode 2.x is 4.0.)
