While it doesn't build from source, I've come across this derivation of which packages the appropriate binary release:
thanks for that link! That should get me going for now until a native package can be to nixpkgs.
Did anyone get this working? I'm quite new to Nix and haven't got a clue where to start with installing a custom package.
Hi Yes, I've got it working , and presumably has as well (whose dotfiles repo I linked to). Typically to include a custom nix package in your config, you merge it into the upstream nixpkgs that your config is already pulling from by using . I do this in my config - my file is just a big function with arguments (aka an overlay). I then (so is now an overlay) and then pass that in the list when instantiating nixpkgs. ( is ). does things a bit differently. They have which is a function with arguments , which returns a derivation (created via ). This then has before that overlay is finally . So in short, you have a package derivation (either the output of or (or other functions)). You need to get it into an overlay function, then pass that overlay function when creating your instance of nixpkgs. I appreciate this is not simple :) Ideally someone can PR this to nixpkgs to make this easier for everyone (though we should really get building it from source working first). I learned myself by piecing together bits of other user's configs. If you want more fine-grained help, check out .
If no one else picks this up in the next few days I might give it a shot if I have time, but as I said in my comment this would need to be packaged as well. Thanks for the amazing explanation above!
is already packaged. One problem that I ran into is that cargo-pgrx is built with rust-stable while seems to need to be built with rust-nightly.

you can see how I got working in my .
Hey! I've just managed to package version (and it took me way too long)! Unfortunately, I was getting a weird linker error on , so I went straight for the beta instead. I'll be keeping an eye for when it releases as a stable version (i.e., ). I have to say that I have not tested it in Immich yet, but it builds and enables correctly on PostgreSQL. With that said, I'll be submitting a draft PR shortly, so that I can start getting reviews. Thank you for telling me about , that helped a lot. I got around the rust nightly limitation by using the env variable and a few patches.
Do you have a link to your repo? I had tried with using the previous methods and it broke my immich. I had to revert to an older database backup to recover and installing (the one that is used by the docker-compose file) and then it worked.
That's not good news :sob: I do have my repo at , but I have not pushed yet. This issue seems to indicate that this will be temporary and they plan to upgrade to a newer version when it's more stable:
Hey! I've (almost) finished the PR to add 0.2.0 (which will be the targeted version in the next version of Immich, see ). I have left some comments about stuff I'm not certain about, so if you have the knowledge to do so, I'd appreciate if you could go there and leave a review! Thank you!
