Accessing import and export symbols ?


Hi everyone ,

I wanted to know the little bit working of a dynamic linker in case of a shared object. When the shared objects are loaded at the time of binding ,an executable will look for an import symbol which is to be exported by a shared library then library which is loaded also contains both its import and export symbols . Since the shared objects have no fixed load address its symbols are accessed from anywhere. Also in elf format there is no separation of import and export tables . The symbol table is maintained through GOT and PLT.

How does a linker know which of the symbols is to be accessed (export or import) without knowing the separate tables ?

Hi,

can i ask what made you choose the "Website Suggestions & Feedback" for posting this question? This forum is clearly designated as being for issues concerning the linuxquestions.org website itself, not other linux questions. was it simply because it was the first in the list?

//moved (although I'd also be interested in the answer to the question Chris posed, so we can help new members avoid the same mistake in the future).
