I’m looking to override a package (https://github.com/NixOS/nixpkgs/blob/b6300babad7334f93f2e2e414dd575a5ba26418a/pkgs/applications/misc/houdini/runtime.nix) to 17.5.229, from 17.0.352, how do i do this (ideally inside configuration.nix)
Thank you
You might wanna use an overlay.
I haven’t tested this one, but usually is just a matter of overwriting the version and src .
self: super:
{
houdini = super.houdini.overrideAttrs ( old: rec {
name = "houdini-runtime-${version}";
version = "17.5.229";
src = requireFile rec {
name = "houdini-${version}-linux_x86_64_gcc6.3.tar.gz";
sha256 = new-sha-256;
(...)
};
});
}
Although I’m not sure how to update your src.

Thanks for the clear example.
Can you tell me where exactly you would put this overlay, and then how to invoke it? It’s a low level question but these kinds of things never click for me until I see a full, concrete example in action.
Hi,
Thanks for that, but ive run into a problem
nixpkgs.overlays = [
( import ./overlays/houdini.nix )
];
{ config, pkgs, requireFile, ... }:
self: super:
{
houdini = super.houdini.overrideAttrs ( old: rec {
name = "houdini-runtime-${version}";
version = "17.5.229";
src = requireFile rec {
name = "houdini-${version}-linux_x86_64_gcc6.3.tar.gz";
sha256 = "b20e0f35c51479fe3f89489ad64122b96f9d14eab26b54dbc062fdbb1681f5e0";
};
});

No idea, might be due to the double recursion at the level and after the requireFile. Usually the src attribute is actually a git repo and not a file.
You need to explicitly pass in the params to the overlay. I think this should work in houdini.nix:
self: super:
{
houdini = super.houdini.overrideAttrs (old: rec {
name = "houdini-runtime-${version}";
version = "17.5.229";
src = super.requireFile {
name = "houdini-${version}-linux_x86_64_gcc6.3.tar.gz";
sha256 = "b20e0f35c51479fe3f89489ad64122b96f9d14eab26b54dbc062fdbb1681f5e0";
};
});
}
Hmm, not sure what im doing wrong. I have that inside my houdini.nix and i get an
error: assertion failed at /nix/var/nix/profiles/per-user/root/channels/nixos/pkgs/build-support/trivial-builders.nix:295
doing show trace i it failed while evaluating ‘requireFile’
but adding { requireFile, ... }: to the top of the overlay doesnt work, complaining about infinite recursion
Ah yeah you need more options set in requireFile. I think this works:
self: super:
{
houdini = super.houdini.overrideAttrs (old: rec {
name = "houdini-runtime-${version}";
version = "17.5.229";
src = super.requireFile {
name = "houdini-${version}-linux_x86_64_gcc6.3.tar.gz";
sha256 = "b20e0f35c51479fe3f89489ad64122b96f9d14eab26b54dbc062fdbb1681f5e0";
};

The error you quoted includes the instructions you want:

So I guess you should go to https://sidefx.com, create an account, locate the file houdini-17.0.352-linux_x86_64_gcc6.3.tar.gz, agree to the terms, and then pass the download URL to nix-prefetch-url.
I’m trying to override the version to 17.5.258, and i have added that file to the store, but my overlay isnt overriding the verison, although there is mention of the new verison in the error
cannot build derivation '/nix/store/859yqhy0nvajp378hhnw8vdfm6ns7h86-houdini-runtime-17.5.258.drv': 1 dependencies couldn't be built
thanks
I just took a look at the source of the houdini package and it looks like
{ callPackage, buildFHSUserEnv, undaemonize }:
let
houdini-runtime = callPackage ./runtime.nix { };
in buildFHSUserEnv rec {
name = "houdini-${houdini-runtime.version}";
extraBuildCommands = ''
mkdir -p $out/usr/lib/sesi
'';
runScript = "${undaemonize}/bin/undaemonize ${houdini-runtime}/bin/houdini";
}
I’m not familiar with the details of buildFHSUserEnv but it looks to me as though the houdini package is itself just a thin wrapper around houdini-runtime and so what you’ve done with your override is produced a hybrid package that tries to install houdini-runtime-17.5.258 but also depends on houdini-runtime-17.0.352.
Without any testing on my part, I’d wager that you need to instead duplicate the default.nix while overriding the runtime portion. This might look like the following (completely untested):
self: super:
let
orig-houdini-runtime = super.callPackage <nixpkgs/pkgs/applications/misc/houdini/runtime.nix> { };
houdini-runtime = orig-houdini-runtime.overrideAttrs (old: rec {
name = "houdini-runtime-${version}";
version = "17.5.258";
src = super.requireFile rec {
name = "houdini-${version}-linux_x86_64_gcc6.3.tar.gz";
sha256 = "1pibc0gmjyw0s9vj0f77idfh41kgjk7l0qfjg4ahlxh84pwhsvzx";
