The difference between the 'deployment target' and 'sdk' are widely misunderstood. Here's something from some post somewhere that I keep in my notes file: ---- The SDK (SDKROOT) you choose specifies the *maximum* version of the OS that you want to *use features from*. There is another build setting, the deployment target (MACOSX_DEPLOYMENT_TARGET) that specifies the *minimum* version of the OS that you want to *run on*. You don't need to use the 10.3.9 SDK to support 10.3.9, the SDK only describes the highest version of Mac OS X you support. You determine the lowest version of Mac OS X you support by setting the "Mac OS X Deployment Target" in the target's build options. Any function that is supported on your Deployment target or earlier are hard linked (and your software won't load on earlier versions of the OS). Any functions that were introduced after your deployment target are weak linked. Any functions introduced after your SDK version are unavailable. ---- So it sounds to me like Eric should use the 10.5 SDK and set the deployment target to 10.4. -- ____________________________________________________________ Sean McBride, B.
