Cross compile Cargo project to Windows msvc target with ease using xwin or windows-msvc-sysroot.

By using this software you are consented to accept the license at https://go.microsoft.com/fwlink/?LinkId=2086102

Prerequisite

1. Install clang (On macOS run brew install llvm and you're good to go).
2. For assembly dependencies, install llvm-tools component via rustup component add llvm-tools or install llvm.

A full LLVM installation is recommended to avoid possible issues.

Installation

cargo install --locked cargo-xwin

You can also install it using pip:

pip install cargo-xwin

We also provide a Docker image which has wine pre-installed in addition to cargo-xwin and Rust, for example to build for x86_64 Windows:

docker run --rm -it -v $(pwd):/io -w /io messense/cargo-xwin \
  cargo xwin build --release --target x86_64-pc-windows-msvc

Usage

1. Install Rust Windows msvc target via rustup, for example, rustup target add x86_64-pc-windows-msvc
2. Run cargo xwin build, for example, cargo xwin build --target x86_64-pc-windows-msvc

Run tests with wine

With wine installed, you can run tests with the cargo xwin test command, for example, cargo xwin test --target x86_64-pc-windows-msvc

Customization

The Microsoft CRT and Windows SDK can be customized using the following environment variables or CLI options.

Environment Variable	CLI option	Description
XWIN_CROSS_COMPILER	cross-compiler	The cross compiler to use, defaults to clang-cl, possible values: clang-cl, clang
XWIN_ARCH	--xwin-arch	The architectures to include, defaults to x86_64,aarch64, possible values: x86, x86_64, aarch, aarch64
XWIN_VARIANT	--xwin-variant	The variants to include, defaults to desktop, possible values: desktop, onecore, spectre
XWIN_VERSION	--xwin-version	The version to retrieve, defaults to 16, can either be a major version of 15 or 16, or a <major>.<minor> version
XWIN_CACHE_DIR	--xwin-cache-dir	xwin cache directory to put CRT and SDK files
XWIN_INCLUDE_DEBUG_LIBS	--xwin-include-debug-libs	Whether or not to include debug libs in installation (default false).
XWIN_INCLUDE_DEBUG_SYMBOLS	--xwin-include-debug-symbols	Whether or not to include debug symbols (PDBs) in installation (default false).

CMake Support

Some Rust crates use the cmake crate to build C/C++ dependencies, cargo-xwin will generate a CMake toolchain file automatically to make cross compilation work out of the box.

ninja is required to enable CMake support.
