Как обсуждалось в этом вопросе , переопределение атрибутов дериваций, которые необходимы для самого Nix, сложнее, чем обычно.
Я пытался использовать код, приведенный в примере, и столкнулсябольше проблем. Вот мой ~/.config/nixpkgs/overlays/main.nix:
_: super:
let coreutils = super.coreutils.override { aclSupport = false; };
in
{
stdenv = super.stdenv // {
overrides = self2: super2:
super.stdenv.overrides self2 super2 // {
inherit coreutils;
};
};
}
Теперь, когда я пытаюсь установить свою версию coreutils с nix-env -iA nixpkgs.coreutils --show-trace, я получаю следующую ошибку:

Я не понимаю, чтопроисходит, это нулевое принуждение происходит где-то в postInstall. Хорошо, я тоже пытаюсь переопределить perl:
_: super:
let coreutils = super.coreutils.override { aclSupport = false; };
in
{
stdenv = super.stdenv // {
overrides = self2: super2:
super.stdenv.overrides self2 super2 // {
inherit coreutils;
perl = super.perl.overrideAttrs (_: { postInstall = ""; });
};
};
}
Теперь попытка установить coreutils вызывает перестроение perl (конечно), что завершается ошибкой из-за отсутствия компилятора C:
./UU/checkcc: line 10: cc: command not found
И вот я застрял. Итак, как переопределить coreutils?
