Hey! I have this configuration to login with ldap: https://tools.immae.eu/paste/qm3z/ when I deploy that and try to login, it fails (I get "Invalid user immae from 1.1.1.1 port 47386"). But if I restart nscd.service I can finally log-in. However this works only until I rerun a nixos-rebuild switch, then I have to restart nscd manually again. Did I miss something in the configuration?

I feel like I have to ask something. Why do we prepend the compiler outputs with system triples when we cross compiling?

I remember getting into trouble doing similar stuff for musl. had to make sure I was either using stuff from the stdenv, passing in the right stdenv, or idk, something

lordcirth: what, is is something like "21.09 is not a version?"

I'm quite new to Nixos, I've read the manual but I can't find a pattern to understand when I can use services.$something. I also looked at the package code on github to find clues and didn't find any.

How do I build something without the daemon, temporarily? Is my only choice to become root?
<azazel>
garbas: I've tried to do the same, but I've stumbled upon a strange problem with the compilation of the "persitent" package: when I do a "pypi2nix -r plone52-buildout-requirements.txt" it exits with an error ( https://termbin.com/evaka ) that i don't really understand. When packaged alone, the process works flawlessly... I'm almost certain it has something to do with the damn setuptools version
<evanjs>
jared-w: right yeah that's what I was wondering. And yes I was thinking something like that might work
<jared-w>
evanjs: I do think something like mkPins would do what you want. The first thing I see is you seem to be using it with a list when it takes an attrset?
<__red__>
but another part of me says that since I have to pull something else in (because there isn't a nixos package for it) to just let it slide
<evanjs>
And I'm wondering if something like the mkPins function might help solve that problem
<evanjs>
based on something from infinisil's config lol. the initial expressoin works fine in terms of building and etc, but if I collect garbage and then try to run nixos-option or etc, well, new-modules was never exactly a "dependency" (only used during build time)

i think lib.mkVMOverride is something the may help, but i can't figure out how to use it.

So I am packaging something which uses make and cmake. One of the makefile targets calls two cmake targets. Once does a whole bunch of detection and copies some python scripts into the /build directory - the second executes them. Problem I have is that when I sheBang them before the target, the cmake un'sheBangs' them.

Has anyone packaged `pgplot` by any chance? It's not in nixpkgs, but maybe someone has an overlay or something?

So I was experimenting with NIS on nixos, and I'd like to talk abuot nsswitch.nix right now that file needs to be changed for every single module that wants to change nsswitch. I was thinking we could do something like nsswitch.passwd.<module>.priority and then have nsswitch.conf build the files array in priority order, omitting anything with e.g. priority = 0. Then this file could remain
<simpson>
It should be something simple, right? Because surely somebody sometimes bumps some single line to change the default GCC on Linux.
<clever>
Taneb: i forget the exact option, but you need to use something like: qemu.networkingOptions = [ "-net" "user,hostfwd=tcp:127.0.0.2:2222-:22" "-net" "nic" ];

I'm running a VM with a NixOS config (something like $(nix-build -E "(nixos { configuration = ...; }).vm)/bin/run-nixos-vm

but I started with something simpler ...
<maralorn>
etalecohomology: Can you post your error message? Does something in your nix-shell fail or the generation of the nix-shell? If gi-cairo fails to build, that might be because that package you create is not affected by the buildInputs to your mkShell.

<__red__>
my head hurts - going to work on something else for a while
<infinisil>
You need to put something in /etc/nixos/nixos-channel/nixos that actually is a path to nixos
<unclechu>
something like `sudo nix-channel --add file:///etc/nixos/pkgs.nix nixos`?
<__red___>
is it considered poor form to open up an Issue against nixpkgs to track my own work on something in nixpkgs?
<cole-h>
If you need to download something, bind it in a let block and use `fetchurl` or something.
<NobbZ[m]>
And if not, it is possible to override with something that is within constraints/known to work.
<lordcirth>
infinisil, ok, so it built, but when I change to "environment.systemPackages = [ inputs.nixpkgs-unstable.ipfs-migrator ];" it says "attribute 'ipfs-migrator' missing". Do I need to do something to the repo to use it?

It’s something in the store
<Peter_Storm>
I read something about maybe having to do some patchelf stuff to make it available to my shell... but I’m in over my head 😅

zecnate: Roughly, a derivation is similar to a makefile in that it represents a way to build something for the nix store.
<clever>

<clever>
so when people come from debian, and expect root installing something to be global, it is
<zecnate>
So with my understanding of nix, the way you would "override" something given that sets are immutable is you create a new set with the default/fallback values plus some new override values.
<zecnate>
Hrm, sorry I don't understand overrides yet. I think the "standard" way to do things in `nixpkgs` is to define functions that take package derivations as arguments, maybe with defaults, then the caller can choose to swap out pacakges, or something like that.
<matthewcroughan>
if/elif scripts that look for a global variable, then set yet another global variable if something is true in the env..

In general, factor out common subexpressions; when you see something defined twice in a block, then you can factor it out and only define it once.

Nix is not a general-purpose programming language, so it's harmful to compare it to something like Python or Rust or C.

zeorin: In general, the binary cache only contains common packages according to fixed configurations. If you've changed something which configures Chromium in some way, then that could be the cause. (And you've got an unfortunate situation, since Chromium takes hours to build.)

then what is a suggested way to package something which just contains assets?
<__red___>
any ideas how to stop that - I'm sure I'm doing something stupid

Maybe the right approach for something like this is to have an overlay repo somewhere which has an always up to date version of `dolphin-emu/master.nix`? Someone would have to set up a cron job somewhere to update it, though.
<clever>
matthewcroughan: having something like ccache involved would poison it all
<simpson>
I bet something else was changed. Maybe channels got updated.
<clever>
matthewcroughan: did you change something involving that?
<simpson>
Although I can agree with something like `dolphinEmuGit = dolphinEmuMaster; # better name`
<clever>
it takes a set containing the old attrs, and returns something else
<matthewcroughan>
so unlike the AUR which has `something-git` packages, nix cannot do this?

<adam_>
I still feel like it's not using -stdlib=libc++ or something
<adam_>
so does clangd use something other then the standard environment
<zeorin>
Suckless's patches tend to do that. They assume you'll just be applying them using `git apply -3` or something, and then it's not such an issue, but when setting it up in Nix it means I have to do it their way first, just to get a unified patch that I must then include in my Nix config.

Is it possible to fetch nixpkgs over ssh? i.e. something like `nix-build -I nixpkgs=ssh://user@1.2.3.4:path/to/nixpkgs`?
<zecnate>

<buckley310>
clever: so in order to use something like "-I sconfig=/path/to..." to override the whole channel, the channel needs to be designed to handle that?

It's less useful on laptops/desktops because (IIRC) it doesn't include any GUI/DE stuff, so the -small channel might advance to a version that's fine for headless use but breaks KDE or something.

I tried a simple overlay to bump a package version, but the build is running rediculously long so I must be doing something wrong:
<Ke>
if I was setting up something now, I might set up 20.09 directly

if the package doesn't exist in stable either, sometimes you can do `services.something.package = (import <unstable> {}).something;` or you might have to set it in your overlay

Was there something done to the purity of builds (or fetchgit specifically) between 20.03 and 20.09?

infinisil: I know... I'm wondering if there's something that does it with a container... "is there a script to do that as a container?"

judson, you can have some place in your configuration that you do `let unstable =... in` and use fetchgit or something else to get it, but if you want to use channels thats how you do it

https://rpi4-uefi.dev things would be much better if there was something like this for every arm board
<samueldr>
misuzu: yeah, good, I was curious if there was something new that made it *completely* unusable
<CyberManifest>
bbigras: glad you found something for you :)
<notgne2>
and she also has both a laptop and a desktop, which both use the same configuration, which is something NixOS lets you do which is very convenient
<CyberManifest>
Yaniel: something an average user wouldn't want to do
<notgne2>
and there's no difference between the bin or built packages, just if you try compiling something the binary cache, it will download it instead
<simpson>
CyberManifest: No, as samueldr was explaining, there's no good options for adding Raspberry Pis to the build farm; at scale, they'd rather have something rackable and etc.
<bbigras>
CyberManifest: ah possibly. but unless I'm doing something crazy with Nix, I don't really code. It's more like a structured config file. When I write a nix module it's something else. I often need help.
<rschulman>
I'm trying to compile something from within a nix-shell that needs the GPU to run. Which of the nvidia packages should I include in the shell.nix derivation?
<apache8080>
is there something additional I need to do to use boost
<ixxie>
Anybody know of a good example of a NixOS module doing something similar?
<Mic92>
Raito_Bezarius: networkd can do something on those lines if I can remember correctly
<arianvp>
I saw https://github.com/kolloch/crate2nix but it only works when my source directory is local afaics; I want to do something similar to cabal2nix where I can do cabal2nix cabal://my-package-2.0 and it fetches it from hackage
<evanjs>
__monty__: infinisil weren't you working on something to replace loaOf?
<alexbakker>
though I'm not sure if that could potentially break something else
<makefu>
hyper_ch: i have something like this at work, i am using a function and map essentially. not sure if it 100% matches your use case though :)
<makefu>
drag0nius: maybe you can start with creating a shared repository of all your hosts' configuration. copy over the config and run nixos-rebuild and you have something which is already very close to what you are looking for
<dramforever>
I think they are going to switch it to the same thing Rust uses, but I hope they keep a version like this (PDF version or something) somewhere
<dramforever>
Like Nixonomicon or something
<dramforever>
or something
<growpotkin>
whats that magic lib command to treat a string as a file? lib.asFile "foo.txt" "Hello, World!" or something?
<growpotkin>
Hey I've got some wonkiness going on with a oneshot service I wrote. I've done a ton but I probably just did something stupid. It's an sh script with the ol '#! /usr/bin/env sh' shebang line at the top. It's kicking back "/usr/bin/env: 'sh': No such file or directory", I can swap it for "/bin/sh" and it'll run but it has no path which is pretty worthless.

<Raito_Bezarius>
is there something to generate nixos module "template" quickly?
<Raito_Bezarius>
something in ~/.config/nixpkgs/... ?
<infinisil>
I suspect something regarding the python packaging changed between 20.03 and unstable
<ornxka>
i can see something failing to build but its unclear what exactly it is
<mjrosenb>
is /nix/var/nix/profiles something that is normally used when running on macos? or is this something special that I got because I tried to install nix-darwin?
<mjrosenb>
I remember I did something silly a while back because as soon as a RC of python-3.9 was available, nix wanted to upgrade to that. I wonder if I installed nix by accideent durning that hubub.
<Ke>
isn't quota just something you configure and nixos does not need to support?
<pingiun>
oh nvm it seems like I was just doing something else wrong
<Graypup_>
curious mostly: is there any particular reason why nix builds don't use something like the systemd dynamic users?
<zecnate>
Does anyone have a feel for what the most popular installation of Nix itself is? Is it mostly nixos users or is it actually Nix-on-debian or something like that?
<dramforever>
as in, not manually but okay if something came with nix, or just no nix at all
<immae>
you can check the logs of libvirtd.service too to check if it says something
<zecnate>
New to nixos. What is the command to fetch and install a specific revision of nixpkgs? I see `nix-channel --add URL` and `nix-channel --update` but I want something like `nix-channel --fetch URL HASH`.
<euank>
chasing down the #! in `/nix/store/.../bin/.ansible-wrapped` and the python wrapped by `$(which python)` in that shell do both give me the same thing. There are something like 3 layers of wrapper scripts here you can poke through to see what PYTHONPATH is being set for various things.
<euank>
bradparker: what's the nix-shell invocation you're using? something like nix-shell -p python3Packages.ansible python3Packages.linode ?
<abathur>
imo, it's not good to try to figure out something new in Nix when you're up against a wall/deadline
<euank>
I've definitely done something like that before to replace a nixos module with a patched one. I'd be a little wary of doing it if the nixpkgs versions differ enough though.
<euank>
I think you could do something like `let experimentalPRNixpkgs = (import builtins.fetchTarball "https://github.com/..../archive/$commit.tar.gz" {});`, and then ....
<euank>
It will be cleaner to bind that import to something with a let though, and it'll let it be evaluated less often I think.

<zeta_0>
i think colemickens might be taking a break or something.
<pittma>
oo I do get something in dmesg now, though. I think this is new…
<colemickens>
nij: give me a second, I need to test something to see how channels work with nix-build.
<colemickens>
unless you're packaging something you'll never actually touch a compiler/make tools/etc.
<Thra11>
colemickens: zeta_0 Assuming you have a nixpkgs checkout with all the history, isn't fetching it with something like `git fetch origin pull/38305/head:packet-tracer` *slightly* better, in that the context might help git to rebase/cherry-pick it more cleanly.
<bobvanderlinden>
yes, i just used `nix-env -iA nixpkgs.nixUnstable` and now `nix develop` is doing something :D
<ldlework>
I just use Win-Shift-(one of the letters above) to move something around to another workspace if it needs to move.
<tomberek>
and you want this to be something that can be `nix-build`-able?
<GolDDranks>
And if touch or echo segfaults, something seems to be wrong. (My gut says that linking is borked? but could be anything)
<zeta_0>
the main problem that i have with nixos is it's lack of documentation, with ubuntu i can quickly find step-by-step instructions on how to do something.

I.e. it's a dependency, it ended up in the path, but something wants to use that without using an absolute path to refer to it
<fzakaria>
(I could give it the VM module but seeing if there's something minimal; it doesn't need to be bootable)
<fzakaria>
(or something with _callPackage_)
<ldlework>
How do I include something like ${SCREEN_SIZE:-800x600} in a nix string being used as script source?
<nicolas[m]1>
I simply expect the formatter to do something like "builtins.replaceStrings ["\\\\"] ["\\"] (builtins.toJSON "\\xDEADBEEF")"
<davidak[m]>
like root was removed or something
<Raito_Bezarius>
or I misunderstood something
<Raito_Bezarius>
is there something to do IPv4 to IPv6 proxy for TLS using SNI preferably in NixOS?
<fzakaria>
Something i've always wanted was also a "continue" debugger like functionality or "next"
<jakobrs>
If I need to package a dependency of a package while packaging something, should I open multiple PRs?
<MichaelRaskin>
Yes, something like that should hopefully work
<cole-h>
Definitely not something I plan on donig :P
<bqv>
something new has definitely happened with systemd, cause it's also broken something else i have
<zeta_0>
i used the nixpkgs manual as a reference, but i'm guessing either my syntax is off or i'm missing something !
<tomberek>
okay, i didn't know that. Old nixpkgs works fine. I see you're using btrfs. perhaps something changed there? (btw: the more recent links you posted are not accessible)
<tomberek>
bqv: you updated all of the filesystem options and ran a nixos-rebuild? (from a liveUSB or something?)
