We’re definitely on a best-effort basis. I think we should try and see if we can make the armhf-linux selection that’s in ‘etc/release-manifests.scm’ build (I think it doesn’t involve Mesa). If we realize it’s out of reach, then we mark armhf-linux as in the same state as mips64el-linux. > i586-gnu: Do we have a mini guide on how to setup a build environment? > Something like "add the childhurd service and the secrets service, with > these bits and you're all set to go"?

Set up a childhurd and offload to it: https://guix.gnu.org/manual/devel/en/html_node/Virtualization-Services.html#index-childhurd_002c-offloading The main issue at the moment is lack of substitutes, which is due to the fact that childhurds won’t start on the build machines behind ci.guix. I’m investigating this here: https://issues.guix.gnu.org/58320 Hopefully we’ll have a bug fix or a workaround soon. > aarch64-linux: I tried a while ago to fix a bunch of the failed builds > on ci.guix.gnu.org and I think I made it worse.

Right, currently there’s something wrong going on with aarch64-linux builds on ci.guix, which Maxim and I have been looking at. In particular, some of the build machines are unreachable right now and may need a kick.

For example, if you want to see why Vim is missing on aarch64-linux, you can run: guix build $(guix gc --derivers /gnu/store/89qy7yb6c0wszq0686xcq4n66h5gy7mb-vim-9.0.0594) (This is assuming you’re on an aarch64-linux machine or that you set up offloading or transparent emulation with binfmt_misc.) Sometimes things build but substitutes are missing, in which case it ends up being infrastructure work. Looking at these issues can be tedious, so let’s join forces and share our progress on IRC to begin with! Thanks, Ludo’.
