Guys, I'm having a problem installing NixOS on VMware. I have partitioned, launched the configuration.nix generation script, modified the /mnt/etc/nixos/configuration.nix, but when I launch nixos-install I get this "the fileSystems option doesn't specify your root filesystem. I have checked, and in fact, there is only swap. Maybe I missed a step or I did something wrong. Any idea?

And one of the occasions was when I tried cross-compiling nano to mingwW64

And configurePhase failed with something about not being able to use ncurses

pkgsCross.mingwW64.ncurses doesn't include the much dlls for some reason, so the ./configure thingy failed to compile a program with ncurses

after all it was cross compilation. ncurses apps to windows. That's basically smooth sailing

<dramforever>
which took forever but was completely automatic

I'm having trouble running a self-packaged program, urxvt is not finding a perl module.

I packaged up https://github.com/Merovius/shellex, without specifying any dependencies (I don't know how), and it can now be installed by nix-env and run. It runs but urxvt gives an error saying "Can't locate X11/Protocol.pm in @INC..." and lists a whole lot of nix store dirs where it is looking.
<porrifolius>
I installed perl5.28.0-X11-Protocol using nix-env. No joy. Added the X11-Protocol output dir in the store to URxvt.perl-lib in .Xresources. No joy. Put a symlink to that dir in my .urxvt/exts dir. No joy. How am I supposed to do this 'the right way'?

Hey! Is there anyone here who uses Nix to setup an environment for building embedded stuff? To target arm MCUs there was `gcc-arm-embedded` before, but now it’s gone and `pkgsCross.arm-embedded.buildPackages.gcc` is not an equivalent: the linker keeps complaning about `-lc_nano` missing.
<ejpcmac>
After some research, this is because `gcc-arm-embedded` embeds newlib-nano, where the new way to go uses newlib.

The only thing I am pondering is that it seems to have a lot of its own modules, rather than inherit from nixpkgs? Why is that? Shouldn't it be able to inherit nixpkgs and adapt them?

That's essentially a merger of the nixpkgs and home-manager repos, which you could certainly argue for, but I'm not sure what the motivations would be.

I.e. the xmonad.nix in home-manager essentially reflects the one in nixpkgs, except for adding a way to handle xmonad.hs.

home-manager only allows for one window-manager?

Don't know, I don't use that module but set it up myself via xsession.

I suppose since home-manager has few ways of doing this but by manipulating your homedir, it's not really possible to give you any options at login time.

Unfortunately no.

I'm still new to nixos and home manager, and I don't want 2 separate repos to set everything up.

Sort of hoped it'd copy the files into a nix/store thing.

Or did I misread?

ugggh, why does XFCE always think that my USB drives are read-only when they're clearly not mounted read-only?
<srhb>
Jomik: What do you mean? (Yes, the files are all in the store)

hodapp: To protect you :D
<jomik>
srhb: I mean, if I have a ~/dotfiles/xmonad.hs, which I point at from my home.nix. services.windowManagers.xmonad.config = "~/dotfiles.xmonad.hs";, is that file then copied to the nix store when I do home-manager rebuild?
<jomik>
Such that a rollback would also result in the changes I made to that file be rolled back?
<srhb>
Jomik: I don't think that's how that particular module works, but it could.
<srhb>
Jomik: I think it leaves xmonad to do its thing when compiling the config.
<hodapp>
annoying. there is seemingly no way to override it
<srhb>
Jomik: Mind, it's pretty easy to change. Just point at your own derivation for the file in the store.
<srhb>
Jomik: (you might have to fiddle with where xmonad puts its binary artifacts, and you lose live reloading, presumably)

I guess I could make a .nix that does the copying and then hand that off to the config attribute.

Jomik: While working on it just use a regular file. When you're done run home-manager switch. Only works with plain files ofc, if your file is generated from a nix expr you need to home-manager build at least.
<jomik>
dermetfan: Couldn't I do it through nix-shell somehow?
<jomik>
I wouldn't be able to use the plain file, because it'd be a symlink to the nix store?
<dermetfan>
Not sure what you want to accomplish with nix-shell, you could simply replace the symlink with a copy of its target

if xomnad.hs is a link to the nix store: cat xmonad.hs > tmp; mv tmp xmonad.hs

Lol... Good point.

I don't know if the xmonad module ia different, or home-manager's implementation, but the i3 module in nixpkgs supports both a path to a config file, and a string with the path, which means just pass the actual path to the i3 wrapper. This is how you get i3 to reload changed configs without changing generations

is there any built-in way in Nix or Nixpkgs to build a tarball containing the closure of something, plus the necessary information to load it into the store? (its references graph)
pkx3 has quit [Read error: Connection reset by peer]
<catern>
*but* still be able to extract that tarball without using Nix tools, so it's suitable for bootstrapping Nix itself? (i.e. not a NAR)
<dermetfan>
Jomik: AFAIK using home-manager it's not possible to choose between multiple DEs/WMs as the display manager would need to know which ones are available before the login. home-manager just generates ~/.xsession though. You should be able to enable plasma5 and xmonad in configuration.nix only and leave home-manager out of the WM/DM/DE
Dagger has joined #nixos
<dermetfan>
what i'm trying to say is that using home-manager you generate ~/.xsession, which starts one certain window manager.
<jomik>
dermetfan: Yeah, that's the plan. But home-manager allows handling configuration of xmonad, etc. BUT, in this case - I will just use home-manager and then specify the configuration file in it, instead of using their service.

They'll refer to the "wrong" package I guess? So I'd risk having 2 xmonad packages - since the one by home-manager would have extras and the one by nixos would not..

But that will cause ,IFD and everyone will glare at you
<tilpner>
,IFD
<{^_^}>
import-from-derivation (IFD) is when you evaluate nix from a derivation result, for example `import (pkgs.writeText "n" "1 + 1")` will evaluate to 2. This is a problem because it requires evaluating some, building some, and then evaluating the build result.
<clever>
mkaito: the ip-magic above doesnt use IFD, but relies on a custom cpp program to generate the file in question
pkx3 has joined #nixos
<mkaito>
why is using a cpp program different in this regard?
<clever>
your not importing the result back to nix, so its not expensive like IFD
<clever>
its just a normal build of a file
<tilpner>
But then the result isn't in "a Nix variable" like how mkaito wanted
<mkaito>
yeah, I see how this works because you generate a file and then operate on that file instead of the value
<tilpner>
import and readFile are equally bad here
<clever>
yeah, you would have to restructure it, to not need the answer in a nix var
<clever>
but to create the file that nix var was going to go into
<mkaito>
right

<elvishjerricco>
Might have those switched up...
<Mic92>
fresheyeball: you can have a chat with vcuncat our DNS guy.
<jomik>
OH, so because it isn't being set by my configuration you mean?
<jomik>
Wait, do I need to declare a default value for submodule types?
<elvishjerricco>
jomik: Yea. If any other part of the config actually tries to evaluate the option, it MUST be defined
<elvishjerricco>
jomik: I'd have to see some more code to tell you what you should do in this case
<jomik>
I have a bunch of nested sub modules. All the final attributes have defaults, but I didn't declare a default for each submodule.

fresheyeball: GPT is a partitioning format

Basically it's the table on the hard drive that defines where each partition lives and how big it is, plus a bit of metadata

fresheyeball: it is the format of the first few bytes on your harddrive.

well if the configuration is too complex toJson might be a reasonable choice

because one also has to maintain the option, which can be error-prone too.

Yes
<clever>
elvishjerricco: thats the difference between menuconfig and i think oldconfig

Well, no. Some fields are special :P
<elvishjerricco>
If so, the easiest thing is probably doing the same thing as `systemd.services.serviceConfig`
<clever>
elvishjerricco: menuconfig just lets you browse things, and choose what you want
<clever>
and options can dynamically hide themselves, based on others
<clever>
no point in having ESP options when uefi isnt selected
<elvishjerricco>
jomik: Sorry, `services.<name>.serviceConfig`. The `systemd.services.<name>` option has some special options under the `<name>` option, and then `serviceConfig` is translated blindly and exactly to the unit file's syntax
<elvishjerricco>
Meaning any unit options that need to be ints that you put in `serviceConfig`, you have to toString yourself

jomik: I mean you can `lib.mapAttrs` the attribute set. But I'm just saying that you need to decide what things you're going to manipulate in Nix, and what things are going to be converted verbatim into JSON
<jomik>
But that doesn't let me change the type I guess?
<elvishjerricco>
clever: So this could be the mythical graphical installer for NixOS? Neat
<elvishjerricco>
We could just auto generate kconfig for all the options in the module system, then provide some special options that automate the essentials like formatting the hard drive
<jomik>
elvishjerricco: I think I was looking for the apply attribute that you can give an option? :P

has anyone set up kerberized nfs4 on nixos?

i've got kerberos (seeming) happy

hey have any of y'all had experience with hnix?
<Growpotkin>
I'm trying to write a program to pull the full list of options from my config, and I was thinking hnix might be useful. But there is a ton of code to sift through without much guidance. I thought I'd see if anybody could immediately steer me away if it's a dead end.
<gchristensen>
what do you mean, full list of options?
<gchristensen>
nixos-option is a program which exists

yeah I had been using that to crudely read one layer at a time
<Growpotkin>
but I haven't seen a nixos-option command to "list all options"
<LnL>
man configuration.nix
<LnL>
or do you need live values?
<Growpotkin>
unfortunately "man configuration.nix" does not include options from modules I have added

I have used "nixos-option" to make a (really inneficient) crawler that accomplishes this task. But it is SLOW AS SIN
<Growpotkin>
mostly because nixos-option dumps way more data than I need, which needs to be parsed at every step
