OSNews is Exploring the Future of Computing

Linked by Adam S on Tue 26th Aug 2008 21:12 UTC

Dynamically linked shared libraries are an important aspect of GNU/Linux. They allow executables to dynamically access external functionality at run time and thereby reduce their overall memory footprint. This article investigates the process of creating and using dynamic libraries, provides details on the various tools for exploring them, and explores how these libraries work under the hood.

RE: Not a good ELF

PE doesn't generate position-independent code, so it's slightly faster than ELF since eg. the EBX register is available to x86 applications to use.

Yes. The difference is typically about 5% for processor-bound tasks on x86_32. I doubt the effect is measurable at all on architectures like x86_64 which are not so ridiculously register-starved.

gcc will produce non position independent code if you tell it to.
