packages/tui/native/win32/README.md
Build both Windows architectures from the repository root:
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:
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.
