nix.dev VS nix-alien

Nix (https://nix.dev/) can provide all of this, although in a smarter way than just through dumping everything in the VCS. Some projects use it already to provide a reproducible development environment and if done right a clean build is just a `nix-build` away.

Author doesn’t mention it but I wonder if tried or considered Nix/NixOS’s reproducible developer environments and ruled them out for any reason. I couldn’t tell from the article if there’s something unique to his requirements that disqualifies them.

https://nix.dev/

if you want something a more in-depth, zero to nix is a great resource for all things nix (they have a section dedicated to flakes here, but i would pay attention to the notice at the top about reading some other things first), along with nix.dev, and of course, the nixos wiki article on flakes

On nix.dev it say I would need to cross compile to make it work, is there some way in which i can build natively on my machine.

Hey

Cachix founder here. Here are a few links for getting started:

- https://nix.dev Nix tutorials

- https://devenv.sh Fast, Declarative, Reproducible, and Composable Developer Environments

Let me know if you have any questions. Domen

Nix pills and nix.dev are my favorites, alongside the official documentation.

https://nix.dev/ is the best in depth resource I know but it's a work in progress.

For folks looking to understand why this is so https://nix.dev and https://devenv.sh/

copy the extracted files over to the nix output dir, and patch-elf all the binaries to link to the nix-version of the dynamic lib.

This sounds more difficult than it is, the result will be a copied over binary file that has its “libc.so” and other dynamic libs replaced in the ELF-header with “/nix/store/hdjdewuieu737-libc/libc.so”. I recommend looking up a package in nixpkgs which has a similar install story, that’s the easiest way to write a new package.

In case you only want to run it locally https://github.com/thiagokokada/nix-alien and similar programs work fine with the binary.

You might be interested in tools like nix-alien which help, though to some extent it's always going to be an annoyance.

There's also nix-alien to run random binaries and nixos-fhs-compat to FHS your OS (might need some tweaking).
