Re: Compiling in Leopard for PPC



OK, now check that you're building using the 10.4 Universal SDK. Open your project settings on XCode and under the General tab there is a setting Cross-Develop Using Target SDK. If it's set to Current Mac OS, that is your problem. That means since you're developing on Leopard, it is making a Leopard only application, Change it to Mac OS X 10.4 Universal and re-build.

I right-clicked in the "Architectures" field and typed in:

ppc i386

They both turned bold face.

Cleaned all targets and built.  Build succeeded.

Copied the app from the "Deployment" folder to the old 10.4 machine.

Still, it crosses out the app's icon and alerts:

"You cannot open the application because it is not supported on this system."

Any ideas why it won't run on Tiger?

Thanks,

John

You need to add ppc to the Architectures list. Valid Architectures only notifies you which ones you CAN use if you want to.

Make it look like this:

Architectures    ppc i386

I recompiled my app in Xcode 3.0 (Leopard) that I had originally built in Xcode 2.4.1 (Tiger) PPC. I *think* it was recompiled as a Universal Binary. In the "Build" tab:

Architectures		i386
Valid Architectures	ppc64 ppc7400 ppc970 i386 x86_64 ppc

However, when I copy the app back to the Tiger machine, it crosses out the app's icon and alerts:

"You cannot open the application because it is not supported on this system."

Aren't Universal Binaries built in Leopard supposed to be backwards compatible with Tiger, Panther, etc.?

Thanks,
