Thank you for the “extremely talented”. Not sure about that one. :-)
That is the command I’m using to investigate a test suite failure in the
‘coreutils-final’ package reported by CI¹. It will bring in the coreutils
build inputs as well as GDB. If you want a minimal environment you can use
this smaller alternative:
$ guix environment -s powerpc64le-linux --ad-hoc coreutils
It assumes that you have binfmt configured to launch the QEMU user
emulator. This happens automagically on Ubuntu (and I assume on Debian as
well) if you install the ‘qemu-user-static’ package.
It also works for other systems such as armhf-linux and aarch64-linux.

Indeed! IBM provides free access to powerpc64le VMs for people doing open
source development:
https://openpower.ic.unicamp.br/minicloud/
I just noticed that there’s a Guix logo on that page, so I guess this isn’t
news for you. :-)

That was very informative. Thank you!

And thanks again for organizing the hang out! It’s a great idea.
