Ruby is a dynamic, open source programming language with a focus on simplicity and productivity.

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


Ruby installer is only available for windows-x64. Emulated version currently fails on Windows 11 arm64 due to this bug: . 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 ( ). This allows to build a native version.

MSYS2 clangarm64 package is now available.

Having a RubyInstaller ready after that will be the next step.


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
