.SYNOPSIS
|
|
Build boringtun (Cloudflare WireGuard FFI library) for Windows.
|
|
|
|
.DESCRIPTION
|
|
Clones or updates the boringtun repository, builds it with Cargo in
|
|
release mode, and copies the resulting static library + C header to
|
|
deps/boringtun/.
|
|
|
|
Output:
|
|
deps/boringtun/boringtun.lib — static library (MSVC target)
|
|
deps/boringtun/wireguard_ffi.h — C ABI header
|
|
deps/boringtun/wireguard.dll — thin DLL shim (optional, not used)
|
|
|
|
.PARAMETER Target
|
|
Rust target triple. Defaults to x86_64-pc-windows-msvc.
|
|
Use aarch64-pc-windows-msvc for ARM64.
|
|
|
|
.EXAMPLE
|
|
pwsh scripts/build-boringtun-win.ps1
|
|
pwsh scripts/build-boringtun-win.ps1 -Target aarch64-pc-windows-msvc
|
|
|
|
.NOTES
|
|
Prerequisites:
|
|
• Rust toolchain (https://rustup.rs) with the target installed:
|
|
rustup target add x86_64-pc-windows-msvc
|
|
• Visual Studio Build Tools 2019+ (for link.exe / lib.exe)
|
|
• Git (for cloning boringtun)
