Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… How do I load a .dylib file so that it resolves symbols in the executable loading it. I have built my lib with "-undefined dynamic_lookup", but I get errors like: dlopen(/Users/holm/Projects/ orbit/oo/build/x86-darwin/src/Open Orbit Debug.app/Contents/ Resources/plugins/libexamplePlugin.dylib, 6): Symbol not found: _omNewClass Are there any special flags to pass when building the executable or the library so it finds the symbols from the executable file? Code loaded at runtime should be a Bundle, not a Dynamic Library. You should build it using the gcc's -bundle_loader option. This email sent to site_archiver(a)lists.apple.com

Unfortunately, there doesn't appear to be -rdynamic for the Mac version of gcc... :-/ This email sent to site_archiver(a)lists.apple.com
