Thanks a lot for your answer.
I've got 2 questions.
1.
So far, I've got these build settings - are they correct?
EF7AD73308BB986600CE4634 /* Release */ = {
isa = XCBuildConfiguration;
buildSettings = {
ARCHS = "$(ARCHS_STANDARD_32_64_BIT)";
GCC_C_LANGUAGE_STANDARD = gnu99;
GCC_ENABLE_OBJC_GC = supported;
"GCC_ENABLE_OBJC_GC[sdk=macosx10.5][arch=*]" = unsupported;
GCC_WARN_ABOUT_RETURN_TYPE = YES;
GCC_WARN_UNUSED_VARIABLE = YES;
MACOSX_DEPLOYMENT_TARGET = 10.5;
"MACOSX_DEPLOYMENT_TARGET[arch=x86_64]" = 10.6;
PREBINDING = NO;
SDKROOT = macosx10.6;
};
name = Release;
};
2.
The customer says he's running a 32-bit kernel.
Doesn't that mean that the screen saver engine and Sys prefs run as 32-bit
apps, too?
3.
Why does it then run on my machine? (which seems to be the exact same
configuration)
Best regards,
Gabriel.
