I've been poking a bit at the MSYS2 builds that @Sebastian Spritzgebaeck Rakel started a few weeks ago, and I've gotten to the point where building

puppet-runtime

runs all the way through, although there's likely some missing libraries and other issues: https://github.com/Sharpie/puppet-runtime/actions/runs/26782841316/job/78951396849 The two main patch sets are for `shared-actions`: https://github.com/Sharpie/shared-actions/compare/27eb341...1f0d7eb And `puppet-runtime`: https://github.com/Sharpie/puppet-runtime/compare/b1956b1...003a5fa Key things I've figured out: • Vanagon needs to run under the

ruby

package, not

mingw-w64-ucrt-x86_64-ruby

. The UCRT package is Windows-native, which means it tries to do stuff like shell out using

cmd.exe

instead of

bash.exe

. The

ruby

package is built to run in the POSIX environment that the MSYS2 shell provides, so it behaves similar to the Cygwin

ruby

that the existing

windows-all-x64

build uses. • When using the

msys2/setup-msys

GitHub action, you end up with TWO copies of MSYS2 installed. The Windows runner image comes with one at

C:\msys64

, and the action creates a separate one at

D:\a\_temp\msys64

. This can cause a lot of confusion. For example, packages installed using

C:\msys64\usr\bin\pacman

won't show up when

vanagon

is running inside of the

msys2

shell spawned from

D:\a\_temp\msys2

. Solution is to always use UNIX paths from inside a MSYS2 shell. Some steps to get the build going on a Windows workstation: • Install MSYS2:

winget install MSYS2.MSYS2

• Launch MSYS2 with UCRT64 mode set:

C:\msys64\msys2_shell.cmd -ucrt64

• Install MSYS packages required to run `vanagon`:

pacman -S ruby make gcc git libyaml-devel

• Disable Bundler parallelism as it seems to deadlock when running under MSYS:

bundle config set --global jobs 1

• Clone my fork of the

puppet-runtime

repo, and run a build from the

msys2

branch:

git clone <https://github.com/Sharpie/puppet-runtime>
cd puppet-runtime
git checkout msys2
bundle install
bundle exec rake vox:build[agent-runtime-main,windows-msys2-x64]
