I got a call the other day (does anyone still use the
telephone?) from a customer who can't run my application. It
turns out they have a G3 running Tiger. I investigated and found
that the latest release of my application's not-so-universal fat
binary only contained code for i386 and ppc7500 (i.e. G4/G5).
SDK is MacOSX10.6.sdk
macosx-version-min is 10.4
Arch is ppc
PPC tuning is G5
The application launches and runs just fine on the MacMini (G4)
and iMac (G5) I keep for testing. Both are running 10.4.11.
Your comment did prompt me to compare the compiler flags being
passed to the two Cocoa applications. The one thing I did notice
was -faltivec was being passed to one and not the other. This
setting was left over from a failed vector processing experiment
and never got turned off. Unfortunately, turning it off makes no
difference. I also can't figure out why it gets passed to the
compiles for one target but not the other, since this flag was
set at the project level. Hmmm.
Anyway, I built the entire project again and then compared the
flags passed to the compiler for both applications, and the
flags are identical.
