Title: Universal binaries and weak linking for 10.3
Hi,
I have an universal binary application which supports 10.3 and now uses some functions in the ImageIO framework which are 10.4 only. I have set the deployment target to 10.3 and the SDKROOT to 10.4u.sdk. When I compile the deployment target is changing to 10.4 so the functions in ImageIO are not marked as weak linked which then causes the application to crash on 10.3.
I am using Xcode 2.2 and the only SDKs I have are 10.2.8, 10.3.9 and 10.4u. Is there a way to prevent the deployment target from being switched?
Thanks,
Dave
