Do you have a "shared object" (usually a shared library on AIX), a UNIX shared library, or a Windows DLL? These are all different things, and your question conflates them all :-(

  • For an AIX shared object, use dump -Tv /path/to/foo.o.
  • For an ELF shared library, use readelf -Ws /path/to/libfoo.so, or (if you have GNU nm) nm -D /path/to/libfoo.so.
  • For a non-ELF UNIX shared library, please state which UNIX you are interested in.
  • For a Windows DLL, use dumpbin /EXPORTS foo.dll.
