I found an answer to the problem below, maybe. It seems that I only
got the warning when I did a debug build.
However, if anyone thinks that the debug build is not the problem,
kindly advise. I have to drive 20 kilometres to test the app on
10.4, so I would like to be as sure as I can that it will run.
A possible scenario: you're making and running a debug build on a 64-
bit machine. There is no 64-bit Objective-C capability on 10.4, only
on 10.5 and higher. The only 64-bit framework/lib available on 10.4
is the BSD layer (System framework).
To confirm using the 'file' command in Terminal:
file /path/to/your/build/Debug/executable
I'm pretty sure you can switch the target CPU for the debug build to
'i386', and that would eliminate the warning. I don't recall exactly
how to do this, but I'm sure someone can provide the details.
And I concur with both of the other suggestions: set the base SDK to
10.5 or 10.6 for x86_64, and get yourself an older, slower machine
for testing.
