At link time, I would open the .tbd file that you find in the lib/ directory of the SDK. For example, /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/libc.tbd It contains, in particular, the sections 'exports: symbols:' (which gives you the list of symbols) and 'install-name:' (which gives you the dlopen'able file name that you can stuff into the executable).
