Question

I have a shared object (dll). How do I find out what all symbols are exported from that?

Answer 1

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 --dyn-syms /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.
