https://www.ruby-lang.org/en/ is a dynamic, open source programming language with a focus on simplicity and productivity.

On Windows, RubyInstaller for Windows is the most used distribution. It’s based on MSYS2 and contains the Ruby Interpreter, precompiled gems (i.e. packages) and a toolchain to compile other gems.

Status

Ruby installer is only available for windows-x64. Emulated version currently fails on Windows 11 arm64 due to this bug: https://github.com/oneclick/rubyinstaller2/issues/308. It’s supposed to be fixed on Windows 11 arm64 insider, but we could not test it at this time.

We implemented the same mechanism (__pioinfo pointer) on windows-arm64 (https://github.com/ruby/ruby/pull/8995 ). This allows to build a native version.

MSYS2 clangarm64 package is now available.

A Ruby installer is now made available.

Build

You need to install MSYS2 and open a clangarm64 shell. Ruby can be compiled and tested using:

# dependencies
pacman -S --noconfirm ${MINGW_PACKAGE_PREFIX}-ruby
pacman -S --noconfirm ${MINGW_PACKAGE_PREFIX}-libyaml
pacman -S --noconfirm ${MINGW_PACKAGE_PREFIX}-openssl

autoreconf -fi
./configure --with-baseruby=$(which ruby)
make
make test
