WoW:3.3.5a

Reverse engineering

Many attempts have been made throughout history to study the internals of this client.

To consolidate and refine our collective understanding, a single reverse engineering repository called binana was invented.

Compiler

For Windows, the client was known to be compiled using the Microsoft Visual C++ Compiler (VS2005, build 50727).

For the Mac OS X port, the XCode version of GCC was used.

Libraries

The WoW client was known to have the following libraries:

• fmod - For in-game audio playback

• lua - Used extensively for Glue and FrameScript. Much of the client runs through this Lua interface.

• libexpat - Used to parse XML, commonly used in GlueXML and FrameXML
