link table

link table

[Mihai Dontu]

Hi,

Does anyone know a tool which I can use to dump the link table?

Basically I want to know how symbols were resolved. Such a tool should 
display:
  - the name of the symbol
  - the type of the symbol (T,U - see man nm)
  - the address of the symbol (as set by the dynamic linker)
  - the module in which this the symbol's address is located

Eg:

myprocess
   U strcmp 0x0040500f (/lib/libc.so)

Why do I want such a tool?
  - I have this program that loads several shared objects (plugins) and 
sometimes the linker resolves the syms in a wrong way making the program 
misbehave (i.e. some plugins have syms with the same name, but they do 
different things - I can not change this because the plugins are third 
party (and closed source)).

Thanks in advance.

M.D.

You can find this on objdump(1) source codes.
