# Windows native prebuilds Build both Windows architectures from the repository root: ```sh npm --prefix packages/tui run build:native:win32 ``` On Windows, the build uses the Microsoft C++ Build Tools from Visual Studio. `build.mjs` locates `VsDevCmd.bat`, initializes a developer environment for `amd64` and `arm64`, and builds the addon with `cl.exe`/`link.exe`. Install the "Desktop development with C++" workload, or at minimum the MSVC toolset and Windows SDK components. No Node headers are required; the addon resolves N-API symbols from the host process. For non-Windows cross-builds, or for custom Windows toolchains, set `PI_TUI_WIN32_TOOLCHAIN=mingw` and provide MinGW-compatible compilers: ```sh PI_TUI_WIN32_TOOLCHAIN=mingw \ CC_X64=/path/to/x86_64-w64-mingw32-gcc \ CC_ARM64=/path/to/aarch64-w64-mingw32-gcc \ npm --prefix packages/tui run build:native:win32 ``` The addon intentionally avoids the C runtime and links only against `kernel32`.
