Linkers, Loaders and Shared Libraries in Windows, Linux, and C++ - Ofek Shilon - CppCon 2023
https://github.com/CppCon/CppCon2023

This talk would give a crash-intro to linkers, loaders and the layout of program binaries, and explore just enough internals to understand some observable differences in C++ builds between Linux and Windows.

We will discuss the GOT, the PLT, symbol visibility, interposition, lazy binding and more. There will be a lot of details, but also a lot of 'why's and opinions.

We will also touch/rant on what the C++ standard has to say on adjacent matters. There's a good chance you've heard before "shared libraries are outside the scope of the standard", but it doesn't mean what you think it does.
