Update flake dependencies #1

Open crims0nHD opened 2 months ago

crims0nHD commented 2 months ago

Hi,

I recently tried to build this project on a M3 Macbook Pro inside a NixOS virtual machine and it did not work. Afterwards I tried to update the flake and the project wouldn't build on a x86-64 machine now either. Since I am still very new at writing Nix and want to learn about the ecosystem a bit, I wanted to ask if you could bump the flake.nix to a more recent version and fix what has changed since, so I can work on getting the project built on Aarch64-linux.

I really enjoy what you have created here and thank you for all the work you put into this!

Kind regards.

Hi! Thanks for your interest!

I would be surprised if the problem was that the nixos version was too old, but I am really busy and this project is not something that I actively work on.

Here's the most likely culprit for it not building on your machine. I would anticipate that cross-compiling from aarch64-darwin will simply not work at all, and I wouldn't try that. But cross-compiling from aarch64-linux should work, I would anticipate. All my aarch64-linux computers are erm, terrible, so I am not going to test it personally, but I would assume it likely it would work if you change the line below.

Unfortunately because flakes are bad, there is no way to set this as an "option" to the flake, so the only options are either:

  1. Write a tiny bit of nix code that generates both attributesnixosConfigurations.fpga-build-on-x86_64-linux and nixosConfigurations.fpga-build-on-aarch64-linux or so
  2. Editing the file

I concur that the NixOS version is old though and porting it to a newer one might be worthwhile! Hopefully it should just build on your machine so you can validate on your machine with the known-working one before working on that project.
