Question

I am trying to understand the process of dynamic linking, in detail. For the purpose, I tried digging into .got section of ELF.

q.1 : I read in ELF Standard 1.2(Appendix) that Global offset table's format and interpretation are processor specific. Can some body please help me, why we dont have standard for this as well and why it has to be processor specific?

q.2 : Can someome point to a tutorial or some thing, where I can get some understanding of operations of a dynamic linker on a live process, examining the contents of .got, .got.plt sections in each step ?

Was it helpful?

Solution

This one covers quite a lot about shared libraries on linux
