It seems like nix-alien fails to build with nixpkgs/master:

The flake's overlay should use prev instead of inputs.nixpkgs... ?

Maybe I'm mistaken about what is expected from overlays, but I thought overlays should work this way and not pull pkgs from the outside.

Anyway, it makes integration with my system a bit harder, the only solution I found so far is to directly use pkgs.callPackage on nix-alien.nix to force the use of my system's pkgs.

Maybe my needs are weirds also, I can explain more if needed :)

Since the flake generated by the test test_create_fhs_env_drv_flake gives an output with system = "x86_64-linux, which of course fails on an aarch64 machine. Using aarch64-linux in the test works results in nix-alien's tests passing and nix-alien works perfectly fine.

This fixes issues with current nixpkgs master where all members of the Python package set are now required to be Python modules

Let me know if this is a reasonable approach or not! I just wanted to get something that worked to demonstrate the root problem

Related: #45

I don't know very well how python works and how it's dependencies are integrated with nix but it looks like mypy is not really needed for the end user.

But nix-alien always wants mypy at version 0.942 which isn't in the cache, which makes every updates quite heavy. On my machines, it monopolize my CPU for about 10 to 20 minutes.

If that's not really needed, would it be possible to avoid this?

Trying to run nix-alien on talon voice fails because no good options can be found for libSkiaSharp.so.

Here are the options presented:

  jellyfin.out                                                                    mission-planner.out                                                             alttpr-opentracker.out                                                        > wasabiwallet.out   
'libSkiaSharp.so'> 

And here is the attempt to run:

/home/nixos/Downloads/talon/talon: error while loading shared libraries: libSkiaSharp.so: cannot open shared object file: No such file or directory

NOTE: I tried each available option presented for libSkiaSharp.so, not just the one above.

I'm unsure of how to proceed here. Given this library is aimed at newer users just trying to get binaries to run, I figured this issue might be appropriate.

One potential resolution being a section added to the readme of what to do in this situation.

Thanks!

It turns out that overlays in flakes use main nixpkgs input, but not the nix-alien's nixpkgs

So this example

          nixpkgs.overlays = [
            self.inputs.nix-alien.overlays.default
          ];

Is incorrect and leads to #34 even if without inputs.nixpkgs.follows = "nixpkgs";

This is just an idea to remove the dependency on nixpkgs and maybe solve the issues with glibc mentioned in #20 .

I didn't encounter any issues so far, but I don't have a lot of experience with this so maybe there are other issues.

Hi, I'm currently using nix-alien in my system derivation and I've recently updated nixpkgs to 7e52b35fe98481a279d89f9c145f8076d049d2b9, this broke my derivation build with the error:

error: 'nixFlakes' has been renamed to/replaced by 'nixVersions.stable'

I've traced it back to nix-alien which uses the now deprecated nixFlakes and removing nix-alien from the derivation does fix the build.

At line 201 in the nixos-installation-with-flakes section, the nix-ld module is put in nixpkgs.overlays. This didn't work on my machine, it should probably be an import.

steam-run is a Nixpkgs tool for running Steam games unpatched, but can be used to run all other Linux programs unpatched. How does nix-alien compare to that?

This is a question, but the answer would be great to add to documentation.

my flack is build success but can't install nix-alien and nix-alien-xx etc... with cmd : fd "nix-alien" only get :

First, thanks for this great program.

When running a program using openGl (e.g. blender) you get an error:

$ nix run github:thiagokokada/nix-alien -- blender
/tmp/blender-3.2.2-linux-x64/blender: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

As far as I see the best solution is to use nixGl:

$ nix run --impure github:guibou/nixGL --override-input nixpkgs nixpkgs/nixos-21.11 -- nix run github:thiagokokada/nix-alien -- blender

This does work but it is definitely not super easy to run... It would be great if nix-alien could directly handle openGl correctly.
