But hidden symbols shouldn't be in the dynamic symbol table and only symbols in the dynamic symbol table have version symbol information associated.
Right! Sorry, I didn't see the hidden symbols were under .symtab, really sorry!
- `Version symbol' entries are greater than 1 if and only if the
concerned library(or DSO) uses symbol versioning.
Yes. But there is no version definition section at all if symbol versioning is not used.
Yes true.
A symbol that is referenced and uses a PLT slot will use the well-defined symbol lookup path. That's the whole point of ELF symbol lookup. Read
http://people.redhat.com/drepper/dsohowto.pdf section 1.5.4.
Sure, I'll do that.
Thanks so much. -- Regards - Prasad
