 man ld

 --export-dynamic
   When creating a dynamically linked executable, add all symbols to  the  dynamic
   symbol table.  The dynamic symbol table is the set of symbols which are visible
   from dynamic objects at run time.

   If you do not use this option, the dynamic symbol table will  normally  contain
   only those symbols which are referenced by some dynamic object mentioned in the
   link.

   If you use "dlopen" to load a dynamic object which needs to refer back  to  the
   symbols defined by the program, rather than some other dynamic object, then you
   will probably need to use this option when linking the program itself.
