julia.withPackages fails when installing Flux

[solna86]

Describe the bug

Instantiating julia with the package Flux fails when resolving dependencies.

Steps To Reproduce

Steps to reproduce the behavior:

1. nix-shell -p 'julia.withPackages ["Flux"]'

Expected behavior

Should instantiate julia with a Flux package precompiled.

Additional context

It seems that there is a problem with dependency resolution, but I'm attempting to install Flux just for CPU:

The issue seems present both in 24.05 and unstable. For many other Julia packages, julia.withPackages works absolutely fine. It is a great addition to NixPkgs.

I haven't had time to dig into this yet, but there was an outstanding issue related to CUDA/hardware specific libraries in general, discussed in the original PR here: #225513 (comment).

However, it looks a bit like a straightforward version incompatibility. One thing to try might be to bump the General registry.

Thanks, I didn't know about this issue, but I assumed CUDA wouldn't be working yet.

Yes, it looks like some straightforward incompatibility. Installing using Pkg inside julia-bin works well. But that of course defeats the purpose of using Nix.
