Not possible to override crane-utils or its dependencies

[fracek]

Hello, I need to compile my project using an older nixpkgs (23.05). The issue I'm facing is that it tries to compile crane-utils using nix rustPlatform which uses Cargo 1.69 but the minimum required version to compile crane-utils is 1.70.

I haven't figured out how to override the rustPlatform used to build crane-utils. If I override crane-utils in an overlay it's not used by crane anyway.

I made a minimal repository to reproduce the issue here

Hi @fracek thanks for the report! At this time we don't have a good way to override/overlay crane-utils:

crane/lib/downloadCargoPackageFromGit.nix

Line 12 in f1dabc4

craneUtils = pkgsBuildBuild.callPackage ../pkgs/crane-utils { };

In the mean time you can get unblocked by either using crane-0.15.1 or using the 23.11 release branch. 23.05 is EOL and we dropped support for it in crane-0.16.0

Thank you, unfortunately I have to target 23.05 to link against a version of GLIBC older than the one included in Ubuntu 22.04 LTS. But I also understand it's a niche use case so feel free to close the issue if it's not worth supporting!
