Introduction

The QuarkslaB Dynamic Linker (QBDL) library aims at providing a modular and portable way to dynamically load and link binaries.

The goals of the library are:

• provide a simple-to-use abstraction to load dynamically linked binaries

• modular enough to be able to load binaries in foreign systems or lightweight sandboxes (e.g. Miasm’s sandbox, or Triton’s engine)

• support loading and dynamic linking of PE/ELF/MachO binaries

• cross-platform and portable library

Notable non goals of the library:

• provide full operating system (re)implementations, like Wine or Darling.

• get the best performance out of all dynamic linkers. Said differently, performance can be scarified for better modularity, in order to make the library usable in various reverse engineering scenarios.

• supports architectures where pointer values are bigger than 64 bits.
