Hi people,
What's the earliest OS I can cross compile for OS versions? Right
now I'm using these settings.
SDKROOT = /Developer/SDKs/MacOSX10.3.9.sdk
MACOSX_DEPLOYMENT_TARGET_i386 = 10.4
SDKROOT_i386 = /Developer/SDKs/MacOSX10.4u.sdk
Now, what if I wanted to let PPC users run my library on MacOS
10.2? Is this possible? Whats the earliest OS I can cross compile
for? I'd rather know than test it out for myself because I don't
actually have MacOS10.2 or 10.1 or 10.0 installed.
It is probably safer to create two targets in your project, one for
Intel only (using 10.4) and one for PPC (10.2) and meld them together
using lipo in a 3rd target that has only a run script build phase.
Just make it clear it hasn't been tested on 10.2. It is not worth it
to support 10.1 or 10.0, even 10.2 is pushing it. I think 10.0 and
10.1 libraries also have binary incompatibilities.
