I get errors as expected, till I end up at the line "linux_4_14_rt = callPackage path"

benley: If you run into some oddities then putting `XDG_DATA_DIRS DEFAULT=@{HOME}/.nix-profile/share:@{HOME}/.nix-profile/lib` in `~/.pam_environment` may resolve them.

there, if I change 14 to 15, I get an error as expected, but when I change callPackage to callPackage1, nixos-rebuild proceeds without complaining
<magnetophon>

I haven't but I probably ought to :-P
<benley>
but yeah, any zfs memory tweaks for nixos should apply equally well to any other linux distro

yup
<pcarrier>
infinisil: I'm guessing there are special considerations with nixos so it works out for initrd modules?
MP2E has joined #nixos
<infinisil>
zfs on linux is the same zfs as on any other distro, nixos has nothing to do with high memory consumptions (with like 99.9% probability)
<pcarrier>

errrr wait sorry

make that boot.extraModprobeConfig

e.g. boot.extraModprobeConfig = "options zfs zfs_arc_max=6442450944";
<pcarrier>
OK thanks. that's what I was hoping for :)
<benley>
and I *think* you can put a list of strings in that option and they'll magically get concatenated together into one multiline string.
<clever>
kernelParams = [
<clever>
"zfs.zio_taskq_batch_pct=50"
<clever>
"spl.spl_taskq_thread_bind=1"
<clever>
benley: this is how i was setting various zfs flags
<benley>
my guess is that accomplishes the same thing, but via the kernel commandline rather than modprobe options
<clever>
the kernel args also let you set options to things that where linked in at compile time
<clever>
so modprobe can never set those
<benley>
of course :-)
<benley>
but I don't think it's possible to link zfs and spl in at compile time, so ...

i'm using the normal pulseaudio setup and I've never noticed a too long deloy
<samueldr>
RT kernels are usually used for live audio stuff
<samueldr>
(or other realtime uses, like automation with hardware)
<samueldr>
magnetophon: how did you add the rt kernel to your configuration.nix?
<samueldr>
(I've loaded musnix, updated my test machine, and want to test)
<clever>
magnetophon: is something actually using the overriden kernel?
rosa has joined #nixos
<magnetophon>
infinisil: for the recording it's crucial that the audio gets full priority, so there are no dropouts, and for the FX software you want really low latencies (less than 10ms) so it feels like the output reaches you as soon as you give input. clear?
rosa has quit [(Client Quit)]

<magnetophon>
in musnix, that is.
<infinisil>
magnetophon: samueldr: I see, thanks!
<samueldr>
not 100% sure, but it looks like you might also need `musnix.kernel.packages` with the proper attribute
<magnetophon>
clever: yeah, I've been using (almost) the same config for as long as musnix exists. when I boot into the profile I have for it, and do uname -a, I see that I have in fact an rt kernel. does that answer your question?
<samueldr>
infinisil: realtime in OS design (afaik) means that when a program asks to run for X amount of time at Y moment in the future, it WILL, guaranteed
<clever>
magnetophon: boot.kernelPackages has to be set correctly to make it use that version
<samueldr>
and, did you change latest_rt to point to 4_14 (dumb question, but you never know!)
<clever>
magnetophon: line 99, it will decide between kernelpackages and linuxPackages_opt, depending on what kernel.realtime is set to

rosa has joined #nixos
<magnetophon>

<magnetophon>

once 4.13 is built and booted (as a sanity check), I'll check for 4.14

<clever>
magnetophon: so i dont think that override will have any effect
<magnetophon>
samueldr: many thanks for your help! I hope you have a use for a rt kernel! :)
<samueldr>
not at all, but I want to help and support here, and I've done my fair share of kernel compilation
<samueldr>
I really need to write-up documentation, but I have an overlay for a kernel fork with support for cheap cherry trail (z8350) tablet platform
<magnetophon>
clever: I have musnix.kernel.packages = pkgs.linuxPackages_latest_rt; and have changed linuxPackages_latest_rt to point to 4.14 inside musnix.
<magnetophon>
<clever>
magnetophon: ah, that may work then
<magnetophon>
clever: doesn't the testing I described above (and in #musnix) "prove" that I have all that set correctly? (genuine question, since *something* is obviously wrong somewhere!)
<samueldr>
magnetophon: assuming what you described is what you did, it looks right, from what I've seen
<magnetophon>
samueldr: well, I'm 100% sure I got the errors where I said I got them (tbc 100% expected errors), and also that I didn't get the errors where I said I didn't get them (that's the weird part)
<magnetophon>
samueldr: maybe do an upstream PR for your overlay? henrytill (author of musnix) will try to upstream these kernels soon as well.
<samueldr>
there's a big issue where the contributor often force pushes over their own branch, it's not intended for direct consumption

hi! with buildEnv I can set up a specific development environment which is started by nix-shell. Sometimes in a dev environment it needs a bit more than having the right packages at hand.. for instance some project specific shell aliases.. is there a way to archive this in nix/nixos?

<magnetophon>

<Olgierd>
hello everyone, I'd like to setup a Nix environment (for use with nix-shell) for developing operating system kernels. I mostly need QEMU, gdb and GCC for target x86_64-elf. how can I make a custom build of GCC, is it better to adapt a package/derivation from nixpkgs or to start from scratch?
<samueldr>
that's with a SATA SSD
<samueldr>
still, hitting the FS, and the SATA bus for every little file kills perfs
* magnetophon
only jumped on the ssd bandwagon last year, and is still amazed by the speeeeeeeeeeeeed!
<infinisil>
Olgierd: Not sure, but I'd start with something from nixpkgs. Just wondering, why do you need a custom gcc build for kernel dev?
<Olgierd>
is compiling GCC with the usual ./configure --target=… && make && make install dance going to work? (I've done this once on a stateful distribution)
<Olgierd>
infinisil: because I need to generate pure ELF binaries without linux-specific stuff, I guess.
<infinisil>
Olgierd: gcc built with nix shouldn't output different binaries than normal gcc
<infinisil>
it only patches the gcc binary, not the binaries it creates
<Olgierd>
I'd have to test on a stock GCC—so far I've only tried to compile kernels with GCC for that specific target ($CPU-elf), and the default is $CPU-linux-gnu or something like that
<Olgierd>
I know Nix has nothing to do with the generated binaries — I just need to build GCC for a different target platform
<infinisil>
So cross compiling gcc?
<Dezgeg>
it really won't matter, consider that you can build the linux kernel just fine with the userspace C compiler
<Olgierd>
yup
<samueldr>
magnetophon: I won't be able to verify the 4.14 boots up entirely since 4.13.7-rt1 decided it didn't like my crypt setup and LVM, but it did start up
<infinisil>
Olgierd: And you can even still use nix to build it, just don't use stdenv
<Olgierd>
what do you mean by not using stdenv?
<samueldr>
(I really like "just" booting an older generation when you screw something up)
<infinisil>
Olgierd: That's what patches the binaries
<magnetophon>
samueldr: I guess that's ok. once it builds, I can test it further. (never had problems with any of the +/- 7 musnix kernels I used)
<infinisil>
Olgierd: Well actually, maybe just preventing the patching only will make it work already, stdenv.mkDerivation is quiet useful
<Olgierd>
btw apart from setting up the toolchain, I would also like to learn about Nix itself, since my greatest achievement so far is installing neovim 0.2 before the package was updated in nixos)
<magnetophon>

this bash overriding sounds rather ugly though, I'd personally never use this

I'll try with your hashes, but logically that shouldn't make a difference, since I should be getting just a "wrong hash" error...
<catern>
hmmm
<clever>
magnetophon: src = ./.; is one common way
<mightybyte>
clever: I tried that and it didn't work.

what does it mean to have not worked?
<magnetophon>
clever: I don't understand
<mightybyte>
gchristensen: I did a "nix-build -K" and the files did not show up in the directory.
<moa>
infinisil: man, that's it!
<clever>
mightybyte: did the build pass or fail?
<catern>
hmmm
<catern>
should I use recursive make or non-recursive make?
<mightybyte>
clever: The build failed, but I suspect that it failed because the files weren't there.
<magnetophon>
samueldr: nope, same result... :( well, we sure tried!
exfalso has joined #nixos
<infinisil>
moa: that indeed seems like it would actually work very well if your aliases and customizations are simple
<samueldr>
it's then possibly a configuration(.nix) issue
<magnetophon>
clever: ah, you where talking to mightybyte, not me. I was confused since I was discussing hashes...
<millettjon>
i had to set useHostResolvConf = mkForce false; and then update, stop, and start the container for it to work
<magnetophon>
samueldr: how do you figure that? I mean, there's not much else it could be, but at the same time we already eliminated that option, didn't we?
<samueldr>
not really, the configuration issues could be from not importing the right musnix path, to having some other option elsewhere that replaces the configured kernel
<infinisil>
moa: Indeed, that's what i was thinking of :)
<magnetophon>
samueldr: what's your nixos-version ?
<samueldr>
working off of 17.09
<magnetophon>
that might be a factor. I'm on unstable
<moa>
infinisil: it's just a bit noisy.. all it needs is a `writeBash` function...
<infinisil>
moa: Another advantage is that you don't need to restart the shell to apply updates (as you would with aliases), since it just searches for the binaries in $PATH, which includes where the stuff gets installed to
<samueldr>
btw, once it starts building, if you cancel and import my closure, than rebuild, it *should* be proof that you can compile at will, and you can test it more quickly

it was built in 17.09, disregard all that
<magnetophon>
I don't understand what you mean, sorry
<magnetophon>
samueldr: ^^^
<samueldr>
I was building the kernel with NixOS 17.09, the compler and environment being different on unstable would mean that you anyway would have had to rebuild
<ivanivan>
I really like the colors and shell config used in the minimal installation CD, but have no idea where they're defined. Can anyone point me in the right direction?

you could have used the closure I linked earlier, to import a pre-built kernel to skip the long build
<magnetophon>
screamin_jimmy: yes, it's supposed to be read-only, though if you insist, you can turn that off in your config. What garbage are you seeing? could it be from previous generations? If you don't mind losing the ability to rollback, you can garbage-collect (some of) those too.

<screamin_jimmy>
magnetophon: me and nixos probaly have a few different ideas :) But I can see getting it to where I want it, then changing back. Honestly, I am not a fan of Loonix. In fact I pretty much hate it but trying this vps thing and what they got is what I get
<magnetophon>

Isorkin has quit [(Ping timeout: 268 seconds)]
<screamin_jimmy>
magnetophon: anynode.net. They seem okay. It's not preinstalled, you have to do it yourself which was kind of an adventure but that's okay. NixOS is about the first thign I've seen in ten years that has any new ideas so of course I had to try it.
<magnetophon>
in general: nixos is a very opinionated system, and if you don't like what it does, there are a *lot* of downsides to it. if you *do* like what it offers, then those downsides are totally worth it, imho.
<screamin_jimmy>
magnetophon: why hate loonix, that subject is too long for the bytes in the Universe. Mostly because nothign works right, tho. Solaris works. Always. Irix works mostly and it's nice to use. loonix just drives me crazy. The little kids writing it don't even know how to sue the alphabet (see their --help files some day :( )
<samueldr>
though, some of the opinions can be bent
<catern>
pie_: surely gcc has a NEWS or a ChangeLog? those are mandatory for GNU projects
<samueldr>
and it stays coherent when bending those opinions (if this all makes sense)
<screamin_jimmy>

<magnetophon>
screamin_jimmy: why would you want to sue the alphabet? ;)

<magnetophon>
bad reason to hate, imho

Hey I am trying to use the coreclr nixpkg for a project using nix-shell. For some reason it's not listed in the official nixpkg search, but it *is* in the nixpkg github repository. Is something wrong with search, or are not all pkgs in the repository included in search?

<Lisanna_>
the web search excludes non-free software

squid. The 3.5 one. The 4+ one MAY have the same situation but I didn't try it yet. Installed with nix-env -i just to try it
<screamin_jimmy>
it also tries to write the rest of its files in a read-only location but starting the program "squid -f /path-to-config" fixed that problem
<ixxie>
disasm: FRidh[m] had a differing opinion than you so it would be nice to decide what to do

that will configure it properly for you

LnL: doing network stuff out of China takes a little extra experimentation. Besides the lying dns anything overseas is SLOW and has a tendency to time out. Local stuff is fine but that doesn't solve my problem.
<toogley>
i want to use that path in some kind of script (neovim clang_complete config). but i don't want to have to change that when the hash (but not the version) changes
<toogley>
what would be the best way to achieve that?
<LnL>
generate the config with nix :)
<screamin_jimmy>
LnL: however, I do think that packages installed according to the directions should not have these hiccups. Putting config files on a read-only file system is not very pretty :(
<LnL>
agreed, but most of that kind of stuff is usually solved in the service module
<LnL>
some packages have defaults that work and some don't
<toogley>
LnL: hm, i manage those files in a separate dotfiles repo, to be also useful with other OS - and i don't want to change that at this point^^

you'll want to specify a package like nixpkgs.hello
<LnL>
that command will try to install _everything_ in nixpkgs
<sphalerite>
pie_: usually installing the package (via nix-env or system config) or entering a nix-shell with the package) should get you the manpages. If not, it's a bug in the package
<sphalerite>
ah right, that's an exception
<toogley>

actually now that you mention it...wow talk about the brain being weird, i never realized a lot of man pages work, its only man 3 thats not present, i could have sworn man pages didnt work for me xD

i meant that

My first guess at this point would be that you're trying to compile C++ as C

aaah well that's a different issue ;)

Hi, I have installed the MySQL package on macOS - with `nix-env -i -A nixpkgs.mysql57`. Anyone know what I need to do to actually get MySQL running? The he Nix mysql57 package doesn't install any launchd files (like Homebrew would).
<b73_>
If I run the `mysql` cmd I get the following error: `ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)`

b73_: nix-darwin brings something like NixOS to macOS AFAIK. Not sure it includes mysql, but I think that would be where it is if anywhere
<sphalerite>
pcarrier: I suspect it might be the nixUnstable bit
<LnL>
sphalerite: b73_: it only has postgres at the moment
<pcarrier>
sphalerite: oh too bad.
<pcarrier>
will try without thanks
<sphalerite>
maybe nixos-install doesn't work with 1.12. Try without it, and see if it works again. I'd consider this a bug in nixos-install though, so stick it on github if it isn't already
<b73_>
@sphalerite oh ok your suggesting that the `mysql` package in the default nix channel is for Linux only (the `platform` metadata for the package seems to support this)
<b73_>
Had not see `nix-darwin` before, but a quick look through the repo suggests there is not a MySQL pacakge
<sphalerite>
b73_: no, it's just that building a piece of software and configuring it are different things, and the package only does the building bit.
<sphalerite>
Configuration is then up to a separate component, like NixOS's module system or nix-darwin
<sphalerite>
It's perfectly possible to run the mysql daemon from the nix package on macOS, there just isn't any ready-made config for it

@sphalerite: nix-darwin sounds like something I should look into... Any idea of the steps to run the mysql daemon without a ready-made config?

my first attempt would be to just run mysqld
<sphalerite>
but what to do when that (probably) fails, I don't really know, I don't know much about mysql
<sphalerite>
Looking at the nixos module would also probably be helpful

yeah when I run `mysqld` from within my nix-profile I get: `mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 2 - No such file or directory)`

you'll need to at least set the datadir

boot live iso, re-create it, boot nixos
<myrl>
hyper_ch: I don't think I have the luxury of recreating.
<myrl>
Err
<hyper_ch>
sure you have
<myrl>
The luxury of time
<gchristensen>
LnL: hm?
<myrl>
It's 2:40 here, I want to sleep. I have classes at 8, travel time's around 30 mins.
<LnL>
gchristensen: ?
<myrl>
And my packages are around ~3G, which takes 2 hours.
<gchristensen>
LnL: you said ":o" a bit ago

<myrl>
hyper_ch: What can I do aside from recreating?
<colabeer>
I want to use powerline in tmux, so I have to put source "/usr/lib/python3.6/site-packages/powerline/bindings/tmux/powerline.conf" into my ~/.tmux.conf how do I do that in nixos? Can I just tell my /etc/nixos/configuration.nix to create this file and put sth like ${pkgs.powerline}/binding/tmux/powerline.conf into .tmux.conf?
<myrl>
hyper_ch: I should be able to mount it on my desktop and dd.
<hyper_ch>
meanwhile you could already h ave downloaded the iso and copied it to a usb stick
<LnL>
gchristensen: the !which channels thing :)
<gchristensen>
oh :)
<myrl>
hyper_ch: I have a full install on my drive.

meanwhile you'd alreday have booted the iso, mounted your nixos and recreated it
<Harpalus>
colabeer: use /run/current-system/sw/lib/… which links to your current configuration

wonders if !which would better serve as a wrapper for nix-locate to find a package serving a binary
<colabeer>
some while back I had a similar problem and then i wrote a python wrapper which could run that script, but I dont remeber how I did that..
<Harpalus>
LnL: okay, misunderstood you, then. It was a wild guess from my side since I figured everything in environment.systemPackages is linked in /run/current-system/…

works fine for me with smplayer
<neonfuz>
is that using mplayer, mplayer2 or mpv
<LnL>
Harpalus: your packages can contain conflicting libraries, so whatever gets linked there is unreliable
<rycee>
gleber_: Yeah, I think the readme no longer is true. The HM services that depend on X may very well work even when HM does not manage the x session.
<Harpalus>
ouch
<gleber_>
rycee: That is my impression
<rycee>
gleber_: If you are able to test this with some module then I'd very much appreciate if you could create an issue on github to say that this. I'll make sure to remove the text.
Harpalus has quit [(Quit: Leaving)]
<rycee>
gleber_: It used to be true that they wouldn't work without HM manager managing the X session, that's why it is mentioned in the readme.
<gleber_>
rycee: It works for me for `compton` and `gpg-agent`, at least. Although I did have to run `systemctl --user start foobar` manually after `home-manager switch`.
<colabeer>
LnL: so how can I link to an external file within a config file? I mean, how do you link from i3config to i3blocks or i3pystatus?
<rycee>
gleber_: The gpg-agent service doesn't require X at all. But yeah, I think compton does.
<neonfuz>
or do I manually need to add "config.pulseaudio = true" somewhere
<colabeer>
LnL: ah sounds good, I'll check it out
<neonfuz>
hmm, I manually set "pulseaudio = true;" in ~/.config/nixpkgs/config.nix and it's reinstalling mplayer now
<rycee>
gleber_: Had a quick look. Seems to me it would be a good candidate for a service!
<neonfuz>
I wasn't aware I needed to set that
<rycee>
gleber_: To start the module you generally can just copy another graphical module. Like the compton or redshift ones.

any way to rebuild all derivations of installed packages and reinstall them?

Is there a trick to getting the Idris contrib package loaded? I'm currently doing `with idrisPackages; with-packages [ contrib ]` and it's not working.
<neonfuz>
the derivation would be different for all the packages that reference "config.pulseaudio"
<jeaye>
neonfuz: Do you have `ao=pulse` in your ~/.mplayer/config?
<neonfuz>
no but I fixed it
<neonfuz>
I needed to set "config.pulseaudio"
<neonfuz>
now it's set, and it works
<jeaye>
Then what's the problem?
<neonfuz>
I just want to reinstall all packages that refence "config.pulseaudio" to fix those packages
<neonfuz>
because I have a lot of software installed
<jeaye>
Nix should handle that all for you.
<neonfuz>
when I run what?
<LnL>
just nix-build / nixos-rebuild
<neonfuz>
what about my nix-env packages
<LnL>
no need to figure out what changed yourself :)
<neonfuz>
nixos-rebuild doesn't do anything to my nix-env does it?
<neonfuz>
oh lame
<neonfuz>
there's no way to re-derive all installed packages?

nix-env -u --leq should should replace everything

thanks
<neonfuz>
that's what I was looking r
<jeaye>
This is the issue with non-declaratively handling those packages.
<neonfuz>
no issue imo
<neonfuz>
just needed to know what to run
<neonfuz>
I'm fine with re-generating all my derivations
<jeaye>
Nothing like that should be needed. Serious issue, in my opinion.

how expensive is it really?

not that bad it sems

the real problem is that nix can leave your system in an inconsistent state where some packages are using an old config

--leq isn't that expensive and fixes that

<simpson>
neonfuz: That's one way of looking at it. Another way of looking at it is that nix-env is inherently flawed because of how it works, and we should all be using nix-shell to set up local environments.
<neonfuz>
true

yeah I think nix-env is flawed especialy tho --leq

sigmundv__ has joined #nixos
<gchristensen>
yeah I think most people don't use nix-enev on nixos
<jeaye>
I would if I could have it declarative, bound to `nixos-rebuild`, and scoped within the user's session. I haven't seen something which allows for all three though, perhaps for lack of looking, so I settle for configuration.nix.
<simpson>
LnL: I have a few X11 and vim things in there because I've been bitten too hard by not having them, but otherwise I've fully converted away from nix-env.

+ nix-shell where needed.

What might be up if a package only works when installed with `nix-env`?
<neonfuz>
simpson: I do understand what leq does and I think it's fine
<neonfuz>
the hashes are what uniquely identify the packages, not the version number, so why do we try to rely on the version number to determine if a package needs to be rebuilt?
<jeaye>
That requires a `nix-env -iA ...` for each user though, not just a `nixos-rebuild switch`.
<jeaye>
In a system with a dozen users, realizing it should ideally just require installing the configuration.nix and running `nixos-rebuild switch`, which builds not only the global system, but also all of the user environments.

Hey all, I'm trying to install Stack properly with Nix (I already have GHC and Hakyll installed properly). So I ended up following some errors down the rabbit hole with that. Right now I'm trying to add XCode 5.1 to the Nix store, which fails with this error: 'error: writing to file: Invalid argument'...And I'm not really sure what to do.
