## Compiler runtime in a source build

A build with the MSYS2 UCRT64 toolchain of `docs/building.md` links these into `totk.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 `totk.exe` |
| winpthreads (mingw-w64) | 14.0.0 | MIT / BSD | linked into `totk.exe` |
| libiconv | 1.19 | LGPL-2.1+ | `libiconv-2.dll`, unmodified, next to `totk.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.

| Tool | Source | License | Purpose |
|---|---|---|---|
| hactool (the installer release ships it, see below) | https://github.com/SciresM/hactool @ `1d64a83450e025622f3468c28fc4164dad2c5ef6`, with patches from MacNativeGames | ISC | NCA and update container extraction |
| Capstone | https://www.capstone-engine.org | BSD-3-Clause | ARM64 disassembly for analysis |
| Unicorn | https://www.unicorn-engine.org | GPL-2.0 (Python bindings BSD) | Differential testing of the lifter; never linked into the game |

## Distributed in the installer release

`tools/make_release.py` assembles these into the release folder of `docs/installer.md`. Versions and sha256 of every download are pinned in that script; licence texts are in the folder's `licenses/` and in each component's own folder.

## Distributed in the Linux release (AppImage)

`tools/make_release_linux.py` assembles these into the folder of `docs/installer.md` ("Linux release") and packs it as
`TotK-Setup-x86_64.AppImage`. Versions and sha256 of every download are pinned in that script; licence texts are in the
folder's `licenses/` and in each component's own folder.
