 qu4pk4 | Hi guys, I am trying to create a Flake that builds older version of OpenSSL. However, I am getting infinite recursion - I suspect it is because I use fetchurl which depends on OpenSSL (I infer this from this comment: https://github.com/NixOS/nixpkgs/blob/nixos-24.05/pkgs/development/libraries/openssl/default.nix#L15). I can send the bare flake.nix if that would help. | 12:23:07 |
| qu4pk4 | I am still quite new to flakes and also to overlays in particular. | 12:23:29 |
| qu4pk4 | {
description = "OpenSSL version";
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
flake-utils.url = "github:numtide/flake-utils";
};
outputs = { self, nixpkgs, flake-utils, ... }:
flake-utils.lib.eachDefaultSystem (system:
let
overlays = [ (final: prev: {
openssl = prev.openssl.overrideAttrs (old: rec{
version = "0.1";
src = prev.pkgs.fetchurl {
url = "https://www.openssl.org/source/openssl-${version}.tar.gz";
hash = "";
};
});
}) ];
pkgs = import nixpkgs {
inherit system overlays;
};
in
with pkgs;
{
devShells.default = mkShell { buildInputs = [ openssl ]; };
}
);
}

 nim65s | do you really need an overlay ? ie. do you want a whole nixpkgs where each and every instance of openssl is "updated" ?t | 12:35:35 |
| nim65s | otherwise, I would just go for:
packages.default = pkgs.openssl.overrideAttrs (_old: rec {
version = "0.1";
src = pkgs.fetchurl { url = "https://www.openssl.org/source/openssl-${version}.tar.gz"; };
});
| 12:36:28 |
| nim65s | or packages.old-openssl if you prefer | 12:36:44 |
| qu4pk4 | Hmm, good point. | 12:40:56 |

| qu4pk4 | Thanks, this worked out for me in the end! | 14:44:13 |
| qu4pk4 | I have read various threads on command line arguments for Flake builds, runs - is it still the case, that one cannot do like:
$ nix run -dOpenSSLVerion=3.1.5
$ nix run -dOpenSSLVerion=3.2.2
And dynamically different package/app would be built?
| 14:45:56 |
| qu4pk4 | It might not work also because the version is then put into fetchUrl, which also needs the hash, but maybe that could be worked around as well somehow. | 14:46:30 |

| Ram | Would anyone mind helping me with a flake I am trying to make? | 02:07:56 |
 tomberek | Sure... what's up? | 02:18:28 |
| Ram | I am trying to make a flake for a simple python flask app | 02:19:17 |

| Ram | I keep getting the following error: error: flake 'path:/home/ram/Flakes/Flask' does not provide attribute 'apps.x86_64-linux.default', 'defaultApp.x86_64-linux', 'packages.x86_64-linux.default' or 'defaultPackage.x86_64-linux'
| 02:20:31 |
| tomberek | Your flake defined a devShell for various systems, but no package. | 02:43:42 |
| tomberek | So if you tried to "nix build" it would fail. A "nix develop" would work, because that command will default to trying the devShell.SYSTEM.default | 02:44:37 |
| Ram | thats the thing it gives me the same error no matter what I run | 02:46:40 |
| Ram | error: flake 'path:/home/ram/Flakes/Flask' does not provide attribute 'devShells.x86_64-linux.default', 'devShell.x86_64-linux', 'packages.x86_64-linux.default' or 'defaultPackage.x86_64-linux'
Did you mean devShells?
| 02:47:25 |
| tomberek | devShell vs devShells | 03:42:10 |
| tomberek | Also, with flake-utils you don't need to have the system in there.... in fact, you don't really need flake-utils there. | 03:44:17 |
