Branch: mingw-host

Supported Targets: x86_64-pc-cygwin (cross), x86_64-pc-windows-gnu (host, only used for building rustc and running build-time build.rs scripts)

It is also possible to make this toolchain link against msys-2.0.dll instead of cygwin1.dll, for how to do this please see this gist

Requires Windows (also support Linux hosts but you need to build from source), MSYS2 and mingw-w64-x86_64-cygwin-gcc package from msys2-cygwin (unofficial)

Host Runtime Dependencies:

Build Dependencies:

NOTE: when using, please add bin/ to PATH

Clone / Configure / Build Commands:

git clone https://github.com/ookiineko-cygport/rust -b mingw-host && cd rust
git submodule update --init --depth=1 --recursive

# IMPORTANT: msys git quirk
export GIT_DIR=/dev/null

DESTDIR=result python x.py install -i --stage 2

you may want export PKG_CONFIG_x86_64_pc_cygwin=x86_64-pc-cygwin-pkg-config.bat CMAKE_TOOLCHAIN_FILE_x86_64_pc_cygwin=${MINGW_PREFIX}/share/cygwin/toolchain-x86_64-pc-cygwin.cmake to allow rust to pick up cygwin packages provided by msys2-cygwin

make sure to unset certain variables which might break cross-compiling by default: unset PKG_CONFIG_PATH PKG_CONFIG_SYSTEM_INCLUDE_PATH PKG_CONFIG_SYSTEM_LIBRARY_PATH

also put these in your ~/.cargo/config to use some 3rd party crates (required if you want to build Rust STD or the toolchain)
