What is w64devkit?

w64devkit is a portable collection of programming tools for writing C and C++ software on Windows. Unlike typical development setups that require installing multiple programs and configuring your system, this kit works by extracting a single archive and running one executable. Nothing is written to the Windows registry, no system paths are permanently changed, and deleting the folder removes everything cleanly. You can carry it on a USB drive or run it from a network share. The kit bundles everything a C or C++ programmer needs in one place: a compiler, a debugger, a build tool, a text editor, standard Unix shell utilities, and a few extras like a compiler cache to speed up repeated builds. The compiler is GCC through the Mingw-w64 project, which produces native Windows programs. The bundled shell and utilities come from BusyBox, giving you a Unix-like command-line experience even though you are running on Windows. Vim is included as the text editor. All the runtime components inside the kit are statically linked, meaning programs you compile do not need to drag along separate library files to run on other Windows machines. The kit supports building programs that target Windows 7 and later for 64-bit systems, and Windows XP and later for 32-bit systems. If you want to build the kit from source yourself rather than downloading a pre-built release, the repository includes a Dockerfile that compiles everything from scratch. This is meant for cases where you want to modify the included tools or verify what you are running. Docker is only needed to build the kit, not to use it. The README also lists a set of offline documentation resources, such as C and C++ reference guides, the GCC manual, and the GDB manual, which complement the offline-first design of the kit. A few small unique utilities are also included, including one for inspecting Windows executable export and import tables.
