Using Rust on Windows - mitaa/rust GitHub Wiki

As of release 0.12, Rust distribution for Windows is completely self-contained and includes all dependencies from MinGW toolchain required for building Windows binaries.

Notes:

1. Rust compiler uses gcc as a linker driver, and will search for it in the system PATH before searching in the private directory. This means that any other versions found on PATH will override the one bundled with Rust, and may cause linking errors if they aren't compatible. The solution is to strip down the PATH in the console session used to launch rustc.
2. The 32-bit binaries produced by rustc will depend on the shared GCC runtime library, libgcc_s_dw2-1.dll, which you will need to distribute along with your program. You'll find it in the /bin directory.
   The 64-bit binaries are dependency-free.
