Building against the 10.4 SDK should root out any 10.5-only method
calls or classes at -compile- time, giving you an opportunity to
check that you're doing the appropriate runtime check before using
them. It will not particularly help you at runtime. And as I recall,
those method calls show up as warnings ("class Foo may not respond to
bar:").

Thanks for your reply. I wasn't sure that switching the SDK would
be good enough to test. My 10.4 box died a couple of weeks ago, so
I have to have someone else run the app under 10.4. It's kind of a
pain, but if I can just switch the SDK and run it under Leopard,
that's fine.
Thanks again.

I don't believe such a switch exists since it's not really a
compiler issue: using a 10.5+ method is completely legal for your
configuration. A quick way to check what 10.5 methods you're using
would be to set the SDK to 10.4 temporarily and see what errors
you get. You can then make sure you're doing the appropriate
runtime checks.

I have a program which needs to run under 10.4, but I used a
method that
is only defined for 10.5. No biggie, it was easy enough to
replace it

find
this out until I ran the app under 10.4. My apps deployment
target is
set to 10.4, and the base SDK is set for 10.5. My question is:
If I inadvertently use a 10.5 only method, is there a way for me
to be
warned at compile time? I know I can use define's to use what's
appropriate for a given target, but what if I overlook the fact
that a
method is only for 10.5? is there a compiler switch or something
that I
can enable to tell me this?
