Okay. Danke mk-soft für den Hinweis. Damit hab ich die Lösung jetzt gefunden:
In meinem Fall mussten die folgenden ImportC-Anweisungen korrigiert werden:
Code: Alles auswählen
-ImportC "/System/Library/Frameworks/AddressBook.framework/AddressBook"
+ImportC "-framework AddressBook"
-ImportC "/usr/lib/libiconv.2.dylib"
+ImportC "-l iconv"
-ImportC "/System/Library/Frameworks/IOKit.framework/IOKit"
+ImportC "-framework IOKit"
Das Problem ist, dass BigSur die Libs und Frameworks vor den Entwicklern und Anwendungen versteckt. Mehr Details hier:

(Kernel -> Known Issues -> New in macOS Big Sur 11.0.1, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286))
