Welcome to the world of dynamically linked libraries and all the fun involved in predicting - and then manipulating - which libraries your binaries see and use … all so you can get the results and performance you expect.

Dr Stephen Sachs from our performance engineering team lives in this world every day, and gave up a bunch of his time to help the Tech Shorts community understand how to use all these tools.

Part 1: readelf, nm, strings, ldd, objdump Part 2: static vs dynamic linking Part 3: RPATH and RUNPATH - manipulating which libraries your executable sees. Part 4: let’s hack a binary to show you how this all works in practice.
