Heya!
I’m trying to setup a flake with argon2. I have the following nix flake
{
inputs = {
opam-nix.url = "github:tweag/opam-nix";
flake-utils.url = "github:numtide/flake-utils";
nixpkgs.follows = "opam-nix/nixpkgs";
};
outputs = { self, flake-utils, opam-nix, nixpkgs }@inputs:
let package = "my_system";
in flake-utils.lib.eachDefaultSystem (system:
let
pkgs = nixpkgs.legacyPackages.${system};
on = opam-nix.lib.${system};
devPackagesQuery = {
# You can add "development" packages here. They will get added to the devShell automatically.
ocaml-lsp-server = "*";
ocamlformat = "*";
ocamlfind = "1.9.5";
utop = "*";
};
query = devPackagesQuery // {
## You can force versions of certain packages here, e.g:
## - force the ocaml compiler to be taken from opam-repository:
ocaml-base-compiler = "*";
## - or force the compiler to be taken from nixpkgs and be a certain version:
# ocaml-system = "4.14.0";
## - or force ocamlfind to be a certain version:
};
scope = on.buildOpamProject' { } ./. query;
overlay = final: prev: {
# You can add overrides here
${package} = prev.${package}.overrideAttrs (_: {
# Prevent the ocaml dependencies from leaking into dependent environments
doNixSupport = false;
});
};
scope' = scope.overrideScope' overlay;
# The main package containing the executable
main = scope'.${package};
# Packages from devPackagesQuery
devPackages = builtins.attrValues
(pkgs.lib.getAttrs (builtins.attrNames devPackagesQuery) scope');
in {
legacyPackages = scope';
packages.default = main;
devShells.default = pkgs.mkShell {
inputsFrom = [ main ];
buildInputs = devPackages ++ [
# You can add packages from nixpkgs here
pkgs."gmp"
pkgs."libev"
pkgs."openssl"
pkgs."libargon2"
];
};
});
}
It seems that libargon2 is installed. Running it in the CLI argon2, I get the response I would expect. However, when running it in my program using ocaml’s argon2 package GitHub - Khady/ocaml-argon2: Ocaml bindings to Argon2, I get the error
libargon2.so.1: cannot open shared object file: No such file or directory
Makes me think it hasn’t properly been installed? Is there a different nix package I should use?
