just compile the application, search for the executable file and apply the ’nm’ 
(names) command.

This will list the “undefined” references that are to be satisfied by the 
shared libraries.

Of course it is a mix of system libraries and GNUstep libraries, but you will 
see the format of Obj-C methods.
