Not to damper your enthusiasm, but you need to be aware the that public API available in 10.4 is COMPLETELY different than the private API from 10.3. It is possible to build code that will work on 10.3 & 10.4, but you'd need to write your code against the 10.3 API. The older API is much more difficult to work with and a lot more arcane. Depending on what your trying to do you may be able to make it work, but if your trying to do something complex it's going to be a hard job. Unless you MUST have 10.3 support, I suggest you target 10.4 where the API is both public, and much more obvious. Which leads to the obvious question- what are you trying to do? Hi Kevin, Maybe I was misled by http://lists.apple.com/archives/Ata-scsi-dev/2005/Sep/msg00014.html - "Disk Arbitration is private on 10.3. It is public on 10.4. Disk Arbitration is otherwise the same on 10.3 and 10.4." I'm aware that the 10.2 DiskArb is completely different, so I'm not planning to support that. Cheers, Andy If you are using Xcode 2.5, you can use the old way to do it: SDKROOT_i386 = /Developer/SDKs/MacOSX10.4u.sdk SDKROOT_ppc = /Developer/SDKs/MacOSX10.3.9.sdk _______________________________________________ Do not post admin requests to the list.

All I want to do is eject and unmount a disk from within a program, so I'm calling DADiskEject and DADiskUnmount (with a couple more calls to get the right objects - see http://lists.apple.com/archives/Darwin-dev/2008/May/msg00016.html). By doing my own link wrapper with dlopen/dlsym etc. it compiles and runs on 10.3, and I'll be testing that it actually works in the next couple of days. You have to use per architecture build settings. In Xcode 3.0, Open you target build settings, select the build settings you want to set (base SDK, deployment version, ...) and then click on the little gear at the bottom of the settings window, and choose "add per architecture settings" (I don't have access to the exact label, but you get the main idea). smime.p7s
