## Compiler runtime in a source build

A build with the MSYS2 UCRT64 toolchain of `docs/building.md` links these into `nx2navi.exe`. The installer release builds with llvm-mingw instead (its row below).

| Component | Version | License | How it is used |
|---|---|---|---|
| GCC runtime (`libstdc++`) | 16.2.0 | GPL-3.0 with the GCC Runtime Library Exception | linked into `nx2navi.exe` |
| winpthreads (mingw-w64) | 14.0.0 | MIT / BSD | linked into `nx2navi.exe` |
| libiconv | 1.19 | LGPL-2.1+ | `libiconv-2.dll`, unmodified, next to `nx2navi.exe`: MSYS2's `SDL3.dll` imports it |

## Build-time tools (not distributed)

These tools run on the developer's or player's machine during the build. They are not part of this repository or of any release.
