PHP 5.6 seems broken when used in a flake

[buurro]

I made an example flake: buurro/nix-php-example

Steps required to reproduce the problem

1. nix build github:buurro/nix-php-example/2845332e938b1df94eb4e823b5b10a8399e2b55b#packages.x86_64-linux.php56

Expected Result

• successful build

Actual Result

error: builder for '/nix/store/9ydf6ry2pnigbwws01fqpiazs33cg0y5-php-5.6.40.drv' failed with exit code 2;
       last 10 log lines:

Running nix build github:loophp/nix-shell#php56 works, so I don't understand where is the issue.

That issue was fixed already, did you update to the latest flake version?

[buurro]

I did. The package doesn't build when used as a nixpkgs overlay.

[drupol]

Running nix build github:loophp/nix-shell#php56 -L works well, so I guess it's because of an outdated flake.lock ?

[buurro]

I just tried recreating the lock file, so I don't think that's it.

Basically using pkgs.php56 returns the error mentioned above, while <nix-shell input name>.packages.${system}.php56 does work, so I'll just start using it 👍

[drupol]

I don't get how such a thing could be possible, but I'm glad you found out a solution.

Should we close the issue?

[buurro]

I think it's because the nixpkgs I'm using are more recent than the ones locked in this repo.

Sure, you can close it.

Thanks
