Overriding nixpkgs.config with IHP flake-parts Module System #2116
Description
Trying to build ihp is failing on MacOs Monterey However this causes an error:
error: Package ‘postgresql-test-hook’ in /nix/store/8han14lkbind4nx63hqq3i2sv6fbqiy5-source/pkgs/build-support/trivial-builders/default.nix:80 is marked as broken, refusing to evaluate.
Per flake-parts I'm trying to update the top level nixpkgs config to 'allowBroken':
outputs = inputs@{ self, nixpkgs, ihp, flake-parts, systems, ... }:
let
sshAlias = "app-prod";
appName = "app";
in
flake-parts.lib.mkFlake { inherit inputs; } {
debug = true;
systems = import systems;
# Here is the module system.
imports = [
ihp.flakeModules.default
];
# Custom configuration to add CFLAGS
perSystem = { pkgs, config, system, ... }: {
#ALLOW BROKEN across all per system definitions of pkgs.
_module.args.pkgs = import inputs.nixpkgs {
inherit system;
config = {
allowBroken = true;
};
};
However this is causing issue
error: The option `perSystem.x86_64-darwin._module.args.pkgs' is defined multiple times while it's expected to be unique.
I can see it is defined here upstream flake-module.nix:
_module.args.pkgs = import inputs.nixpkgs { inherit system; overlays = config.devenv.shells.default.overlays; config = { }; };
Is there a way of passing in app level flake config to this top level function or do we need to add a perSystemOption to the ihp.flakeModules.default?
