@eyjhb:eyjhb.dkeyJhbTried to work on getting the nixpkgs version up-to-date with 23.11, but that's a challenge.. Stuck on trynig to get clang things to work with lineageos.. Something something ncurses not being found. 23:08:24
@eyjhb:eyjhb.dkeyJhbBut doing the same trick as in grapheneos requres a bigger change than expected.23:08:43
@eyjhb:eyjhb.dkeyJhbAlso, not suer how ot avaid NIXPKGS_ALLOW_INSECURE, as some places "require" python2 for building. Mostly older Android versions.23:09:42

@atemu12:matrix.orgatemu12 eyJhb: If they become a bother, feel free to drop them 01:31:22
@atemu12:matrix.orgatemu12Though if you can, I'd prefer simply only including them optionally depending on the android version01:31:46
@eyjhb:eyjhb.dkeyJhbThe first thing I'm trying to do, is to get it to build by specifying the allow insecure envvar. Then I can check which ones I can bump to python208:17:49

@eyjhb:eyjhb.dkeyJhbThe current issue is the clang thing08:18:04
@eyjhb:eyjhb.dkeyJhb

But I bumped the entire flake.lock, I don't think that's ideal.

@Atemu is there a good reason for unstable and 21.11 pin? Couldn't it just be 21.11 or something?

08:44:04
@eyjhb:eyjhb.dkeyJhbOr just be unstable. Not sure which is better.08:44:12
@atemu12:matrix.orgatemu12Nono other than that I haven't been able to make them work10:40:55
@eyjhb:eyjhb.dkeyJhbFair :D10:55:55
@eyjhb:eyjhb.dkeyJhb

It seems like lineage needs the same treatment as grapheneos after bumping to 23.11, as shown here https://github.com/nix-community/robotnix/blob/c54c511b3aa3e827e7ae320d604646a0ecc7c96c/flavors/grapheneos/kernel.nix#L25-L36 , I've just initially tested it by adding

      "prebuilts/clang/host/linux-x86/clang-3289846".src = pkgs.stdenv.mkDerivation rec {
        name = "lol";
        src = config.source.dirs."prebuilts/clang/host/linux-x86".src + "/clang-3289846";
        buildInputs2 = with pkgs; [
          zlib ncurses5 libedit
          stdenv.cc.cc.lib # For libstdc++.so.6
          python39 # LLDB links against this particular version of python
        ];

        postPatch = ''
          ls -al 
          # rm -r python3
        '';

        buildInputs = with pkgs; buildInputs2 ++ [ autoPatchelfHook ];
        installPhase = ''
          runHook preInstall
          rm -f env-vars
          cp -r . $out
          runHook postInstall
        '';
        
        autoPatchelfIgnoreMissingDeps=true; # Ignore missing liblog.so
      };

To the source.repos in flavours/lineageos/default.nix. Most likely it needs to reside a different place. Maybe.

@eyjhb:eyjhb.dkeyJhb Feel broken, mostly because I'm not sure what I am even doing. Atemu is lineageos using a prebuilt kernel, and the vanilla and grapheneos is not? Ie. they are built using robotnix? 12:54:13

13:03:13
@eyjhb:eyjhb.dkeyJhbFun, now it just fails further about libncurses.so.5 complaints. Not sure what changed in nixpkgs, that warrants these errors all of the sudden13:03:36

I think so yes 		15:07:10
@atemu12:matrix.orgatemu12Ah no, nvm I remember: It has kernel sources that are built during the android build15:07:36
@atemu12:matrix.orgatemu12For Vanilla/GOS we use "prebuilt" kernels that we build in Nix15:07:59
@eyjhb:eyjhb.dkeyJhbI can't make any sense of the latest error I'm getting. I'm now just trying to bisect nixpkgs, to figure out why libncurses.so.5 suddenly can't be found.15:08:01
@atemu12:matrix.orgatemu12But I have never really touched Vanilla15:08:10

Makes sense :) 		15:08:28
@eyjhb:eyjhb.dkeyJhbI'm going slightly insane over why ncurses5 suddenly can't be found when bumping nixpkgs. It doesn't make much sense to me.15:08:54
@atemu12:matrix.orgatemu12I vaguely remember ncurses being a bit cursed (heh)15:09:42
@eyjhb:eyjhb.dkeyJhbIndeed.15:09:49
@atemu12:matrix.orgatemu12https://github.com/NixOS/nixpkgs/issues/8976915:10:03
@eyjhb:eyjhb.dkeyJhbGrapheneOS does SOMETHING funky with it, which I'm doing as well, then it passes the first part. But then fails with another libncurses.so.5 for the bcc_strip_attr15:10:28

This issue is from 2020, we're using a 2021 nixpkgs version . But might be the issue? 		15:11:18
