It seems that implicitly linked libraries do not honour -L paths (even if -Z is passed), hence, a program which links in libSystem.dylib will fail to link. eg: The cross-development feature was introduced to allow developers to target older system releases with the latest toolset. If it doesn't work going the other direction it may be (note my speculation) because it was never tested that way. The suggestion to ask on a tools-related list is a good one. This may also warrant an enhancement request/bug report. smime.p7s

I think that Ditto uses BOM (and possibly CoreServices). There was just a thread about BOM (closed source). -- Finlay _______________________________________________ Do not post admin requests to the list. They will be ignored.

Use the Developer Tools appropriate for your OS. If you no longer have your install media, you can download it from connect.apple.com with a free ADC membership.

Substitute all mention of 10.4 with 10.3 and 10.3 with 10.2 if you like. Ok if not specific to 10.4 consider asking on the xcode[1] list since Apple folks that know how the SDKs work are more likely to be around (they may give an answer in terms of Xcode but from that you can workout what you have to replicate).

Let's say you have app which dynamically links to lib1 which links to lib2. lib1 and lib2 are in /that/directory although they have dylib names in /usr/lib. Setting DYLD_LIBRARY_PATH to include /that/directory will let the app link to lib1 without -L or -F, but it still won't find lib2. You can include both libraries in -l. While that's a pain to do because you have to anticipate the entire dependency graph, it might be easier than what you are doing now. DYLD_LIBRARY_PATH has nothing whatsoever to do with the linker. I would have thought that setting the NEXT_ROOT environment variable (which xcode does as far as I know) would fix this. This email sent to site_archiver(a)lists.apple.com
