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. > This talented and mysterious developer also mentioned that IBM does > provide power9 VMs that you can request access to, which would make the > debbugging process a little smoothier. 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. :-) > I talked about my current email server and other things.

It’s a great idea. -- Thanks, Thiago ¹ https://ci.guix.gnu.org/build/692547/details
