What Does the Linker Actually Do for Us?

Explore the inner workings of linkers in this comprehensive conference talk from ACCU 2021. Delve into the process of how linkers combine C++ code and libraries to create executable programs. Gain insights into object file contents, the components needed for a complete executable, and key concepts such as sections, symbols, and relocations. Examine how code and data are managed in programs and understand the influence of operating systems on linker operations. Investigate C++-specific aspects like template instantiations and inline function management. Learn about tools for examining object files and executables, demystifying the linking process. Suitable for developers with experience in compiled languages like C or C++ who want to deepen their understanding of the final step in the toolchain.
