Sometimes not all platforms are displayed

[mio-19]

Sometimes not all platforms are displayed on the search page.

Here is an example podman-desktop

I can see darwin in platforms when running this command in nixpkgs

$ nix eval .#podman-desktop.meta --json | jq

  "platforms": [
    "x86_64-darwin",
    "x86_64-linux",
    "armv7l-linux",
    "aarch64-linux",
    "aarch64-darwin"
  ],

Platforms seems to be inherited from electron: https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/by-name/po/podman-desktop/package.nix#L154 Which indeed currently seems to be specified as linux: https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/development/tools/electron/common.nix#L264

It explains the behaviour. There is a different concept that is platforms that I can build and run the package. I encountered some packages that I can build on darwin but darwin isn't in platforms. What terminology should I use for it?

Do you have NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1 or allowUnsupportedSystem = true set?

If you believe the package should be supported on darwin then perhaps PR an update to the platforms to mark it as supported?

yes

$ nix eval .#podman-desktop.meta --json | jq

  "platforms": [
    "x86_64-darwin",
    "x86_64-linux",
    "armv7l-linux",
    "aarch64-linux",
    "aarch64-darwin"
  ],

But in nixos search only linux platforms are listed

[mio-19]

The challenge is that we pick electron.source or electron-bin depending on the platform

The result of the command nix eval .#podman-desktop.meta --json | jq is different on mac and linux

aaaah that's a good observation.

not sure how or where this should be fixed, though...

[booxter]

We can fix it package by package (and we probably should!) but nixos-search could probably eval for both linux and darwin and combine the lists?

[raboof]

I think I'd be OK with that, yeah.

[emilazy]

Hydra only evaluates for Linux so this kind of problem can't be fixed solely in the search site. It can lead to packages not being built.
