[sikmir]

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux (cross)
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking

I build nix build -L .#pkgsCross.armv7l-hf-multiplatform.guile-hall on macos and that's OK. What platform you are trying to cross compile for?

I've tried pkgsCross.aarch64-multiplatform.guile-hall and pkgsCross.riscv64.guile-hall on x86_64-linux, both fail the same way

Yes, I've managed to reproduce it on x86_64-linux.

For guile (3.0) cross-compiling I have locally:

preBuild = ''
  touch -d "1 days ago" libguile/scmconfig.h
'';

I don't remember whether it really worked. And it is a bit of a hack anyway.

I have no idea how to fix guile cross compilation on linux (it's ok on darwin). So, maybe it's for separate PR.
