@grimmauld:grapevine.grimmauld.deGrimmauld (any/all) Quick heads-up:
I believe https://git.lix.systems/lix-project/lix/src/commit/e101400359558ec89f0a3afa29631ca1b6546fd3/lix/libutil/processes.cc#L20-L22 should be unconditional. On glibc gcc this header is included implicitly. On musl llvm, that include is needed or otherwise SYS_capset (https://git.lix.systems/lix-project/lix/src/commit/243836ed0a0b963eebd033d109e6cb817d67fde4/lix/libutil/processes.cc#L414) is undefined.

On my dev machine I'm getting:

+(tarball.sh:31) nix-build -o /tmp/nix-test/tarball/result -E 'import (fetchTarball { url = "file:///does-not-exist/must-remain-unused//tmp/nix-test/tarball/tarball.tar"; sha256 = "sha256-PRgXPIzueCAIFHesj5pSLlDYbJsrGmUD8B9gpbs9p9Q="; })'
++(tarball.sh:36) mktemp -d
+(tarball.sh:36) export HOME=/tmp/tmp.0S4oIlI3Xo
+(tarball.sh:36) HOME=/tmp/tmp.0S4oIlI3Xo
tarball.sh: line 37: TMPDIR: unbound variable

Seems like function tests need to provide a sensible default for TMPDIR if it's not set

@olivia:computer.surgeryolivia changed their profile picture.00:23:19
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Also any clue as to what's going on here? https://buildkite.com/lix-project/lix/builds/5888/steps/canvas?sid=019a8f19-65cf-4acd-9593-5d6bcd790abf#019a8f19-668b-4cbb-99c2-e68a72269606/18-32 The error message is coming from the host lix and not the one that's being built? Seems fucked00:25:14
@raitobezarius:matrix.orgraitobezariusI am going to take a look, I hope I didn't fuck up something with my recent infra work00:28:24
@raitobezarius:matrix.orgraitobezariusNormally I didn't touch this host neither its daemon setup00:28:35
@shalokshalom:kde.orgShalokShalom joined the room.07:52:34
@shalokshalom:kde.orgShalokShalomThe email confirmation for your git doesn't let me in, so I drop this here: https://nix-community.github.io/home-manager/index.xhtml#sec-usage-gpu-non-nixos This new mode for GPU support got merged last week. You might wanna update the README, that speaks about NixGL (only)07:53:37
