GCC/ELF - from where comes my symbol?

Question

There is an executable that is dynamically linked to number of shared objects. How can I determine, to which of them some symbol (imported into executable) belongs ?

If there are more than one possibility, could I silmulate ld and see from where it is being taken ?

Answer 1

Have a look at nm(1), objdump(1) and elfdump(1).

Answer 2

As well as the ones Charlie mentioned, "ldd" might do some of what you're looking for.
