Itkovian has joined #nixos
<DIzFer[m]>
The most striking difference is in that your new package is not a function, you had to comment out the arguments...
<kuznero>
I was trying to learn how to customize package if I don't get what I need from std one. Thus I took what I found in nixpkgs and tutorial example on how to do that here: https://nixos.org/nixos/manual/index.html#sec-custom-packages Which does not have it as a function. Do you know how do I turn it into one if that might help?
<kuznero>
Having empty install phase didn't help
<DIzFer[m]>
I got custom packages working with a normal (as in, same file structure that would go in nixpkgs) nix file that's imported under nixpkgs.config.packageOverrides
<kuznero>
DIzFer[m]: I will try with simple packageOverrides now, I just need to add postInstall with creating additional symlink... That should help... Moment
<DIzFer[m]>
No idea why, I'd try making the full package an override :/
<kuznero>

Alternatively, how do I get virt-manager to connect to virtd?

Hm, that was possibly using a "user session" in virt-manager, but networking doesn't seem much easier with the GUI. :-)

Typically my LD_LIBRARY_PATH is /usr/lib/x86_64-linux-gnu:/lib/x86_64-linux-gnu/ but with this setting nix will find first glibc 2.24 while the hello bin used glibc 2.25. Resetting the ld lib path to nothing helps.

When I try something like sudo qemu-kvm -netdev bridge,br=virbr0,id=test1 -- I get "bridge helper failed"

Is there some dependency I'm not aware of?
<clever>
Rodenbach: anything compiled by nix expects LD_LIBRARY_PATH to either be blank, or to contain the opengl drivers
erictapen has quit [(Quit: Leaving)]
<Rodenbach>
Okay, so I can blank it out first if that should be required. At least for now, while just learning how this works this will be fine.
<clever>
everything on nix has an rpath set, which contains the absolute paths for things like libc
<clever>
and this allows different programs to depend on different libc's
ertes-w has joined #nixos

Is virbr0-nic supported to be the hosts interface into the virbr0 network?

srhb: 'ip link' should show what bridge things have been enslaved to
takle_ has joined #nixos
<clever>
srhb: and if you want it to get into the internet, you also need to add the main ethernet card to that bridge in the nixos config
<layus>
Rodenbach, may I ask why you need it ?
<srhb>
I don't want that (for now) -- I just want the guests to be able to communicate with the host and vice versa.
takle has quit [(Ping timeout: 246 seconds)]
<clever>
srhb: "bridge helper failed" implies that qemu is supposed to be running a scribe to deal with bridging, if you dont need very fast network, you can just omit -netdev entirely, and qemu should setup userland nat
<clever>
s/scribe/script/
<Rodenbach>
layus: why I need the ld path? I am using some applications in my company environment which expects this to be set.
<srhb>
clever: I'll try that after lunch, thanks.
<srhb>
Wait, how does NAT help me? How do the guests talk to the hosts with NAT?
<srhb>
I'm supposing the guest AND the host need to have an address on a shared networkl
<clever>
the userland nat in qemu will decode packets the guest tries to send out, and turn them into a simple bytestream
<clever>
then it opens a normal tcp connection on the host, and sends it to linux, which re-packetizes it
<clever>
so the guests can get internet access without having to give qemu root
<clever>
and it needs zero config
<layus>
Rodenbach, the way nix handles custom configuration like that is to wrap binaries with a small shell script that sets the variable, instead of propagating it everywhere. If you keep using nix, it may be your wisest move ;-)
<layus>
Just write a small wrapper in ~/bin for you company application commands.
<Rodenbach>
layus: this is possibly what I’ll end up with, or… even doing the switch to NixOS one day.
<Rodenbach>
For the coming days it’ll be fine to manually reset the path back and forth. I want to learn how I can use nix to create Docker images in a repeatable way.
<layus>
Rodenbach: \o/ !
<Rodenbach>
Yeah, right now we can’t delete older images, as it might not be possible to rebuild them correctly. But with nix we are basically free to remove older images. In case somebody needs it back we can easily restore it. That’s the hope.

Hi there
<nixy>
Heya
ilyaigpetrov has joined #nixos
<Rodenbach>
I would like to ask what value Nix provides. In the sense of: what manual steps does it abstract away? I personally would guess that it basically is semantically similar to snapshotting the whole repository of packages as soon a new one gets added.
<Rodenbach>
I would imagine that this is being done by making use of some functional data structure (a bit git like, but working nicely for big binary files) and does not literally need to clone the whole 500GB repo.
<Rodenbach>
In principle I could manually do this, by using some Linux distro, say, Debian, and download all packages and store them in git. And my Dockerfile would explicitly set its sources to my local disk instead of using remote ones.
<Rodenbach>
Is this basically the core idea? Nix is doing something like that, but obviously not using git but some specialized mechanism. So that the Nix servers do not require an 800 exabyte disk on which every single fully cloned repository gets stored, but instead where one can easily deliver specific binaries of a specific version?
<srhb>
Hmm. I don't think I want userland NAT. I want to be able to set up a dhcpd on the host which the guests can access for PXE
<srhb>
(Well, and a tftp server)
<goibhniu>
Rodenbach: nix makes such a process very easy to manage, and share with others
<clever>
srhb: qemu can also embed a tftp server inside the userland nat for you
<srhb>
Oh, yes, I remember seeing something about that.
<ToxicFrog>
Ok, I think maybe I'm just bad at nix-channel and it's only broken in unstable, but it's hard to tell because I can't build this system configuration in 17.03 either, but for different reasons -- it's failing to download one of the files:
<clever>

Anybody here knows of a tool to show the last n lines of an *active* pipe? Like tail, but streaming. Pipe gets output of a program and I want my terminal to show the last two lines read from the pipe
<symphorien>
tail -f ?
<chpatrick>
goibhniu: I don't think it's relevant, that just selects an attribute from a nix expression
<the-kenny>
symphorien: doesn't work as the pipe doesn't include EOF yet. Tail doesn't know where to start.
<clever>
chpatrick: when you run nix-shell like that, it will drop you into a shell suitable for building the derivation you pointed it at
<the-kenny>
symphorien: plus I want to actually clean the terminal when new lines appear. More pager-like than tail.
<chpatrick>
clever: but if I just run cmake in that shell it doesn't behave like the cmake invocation nix uses

My go to for searching for this would have been `nix-env -qa .*keras.*`
<layus>
I was not too sure about this, but FRidh does an amazing job at maitaining python packages, so i would trust him.
<layus>
You can always define aliases.
<amosbird>
error: selector ‘.*keras.*’ matches no derivations
<nixy>
Then I guess I should rephrase that. An alias should be defined in cases like this

can nix-env -q be case insensitive?

TweyII has joined #nixos
<amosbird>
hmm, that seems a nice feature to have
TweyII is now known as Guest63670
<clever>
but its regex, so you could do .*[kK]eras.* if you wanted to
<layus>
why not `nix-env -qaP -A nixos.pythonPackages | grep -i keras` ?
<clever>
yeah, thats simpler
<clever>
you can also grep -ir on nixpkgs
<layus>
I often find grep better than nix-env regexes
<clever>
$ grep -ir keras --color ~/.nix-defexpr/channels_root/*/pkgs/
<amosbird>
ok
<nixy>
Sure, but why would I, assuming I am new to NixOS, even think about issues such as case insensitivity and piping to grep for a tool that supports regex?
<clever>
and a grep directly on nixpkgs (not nix-env) will find the attribute i pasted when i first found Keras
<clever>
grep on nixpkgs can also find the domain for software where the name isnt clear
<amosbird>
hmm, grep: /home/amos/.nix-defexpr/channels_root/*/pkgs/: No such file or directory
<clever>
amosbird: the exact path will differ between nixos and centos, look around in that area

I'm trying to compile a library that require CUDA, but so far no luck :-/ ... basically I have `cudatoolkit` in my env, but when I run `ld -l cuda` it says "cannot find", does anyone have an idea? is there an other package to install?
<joehh>
thanks very much :)
<qknight_>
joehh: try it but verify that this is what you really want
<aloiscochard>
fwiw, I found my issue, the `libcuda` does *not* comes with `cudatoolkit` but from the NVIDIA driver /cc qknight_
<chpatrick>
aloiscochard: if you're running nix cuda stuff from a different host distro, we found that you need to LD_PRELOAD libcuda and libnvidia-fatbinaryloader from the host system

but -p works only with nixpkgs, as far as i can tell

nix is precompiled*
<copumpkin>
it's more like why jump through various hoops to pull in slightly different versions of dependencies from other package managers/ecosystems when we have our own dependency-management system
<copumpkin>
and even the install script just puts nix into the store just like any other package
<domenkozar>
copumpkin: to confirm Nix can be compiled on those distributions
<domenkozar>
of course you could not support that
<domenkozar>
but people do it
<copumpkin>
oh, but I thought we also distributed debs and rpms?
<copumpkin>
if it's just a test that makes a lot more sense to me

I was missing my language's dictionary pkg from hunspell, that was a boring one
<copumpkin>
so the RPM/deb outputs are just because we produce them as part of our tests?

well we also used to serve them for installation
<domenkozar>
but the goal is to also test if Nix is compilable on those distros

since you could potentially develop it there

which didn't exist back then :D

I was paid to write Haskell for a month. My CTO decided to use Go instead because he understood the language more. Despite Haskell being ~20x faster :(.

May have been poorly written go.

If it makes a difference, I would be willing to help out with the beamPackages stuff once I get a little more acquainted with nix.

hey, I'm new to nixos, and have just hit a bit of an issue installing python packages. pip seems to want to save installed packages to a read-only filesystem. what's the nix-ish way of handling this sort of thing?
<mdash>
Pypi2nix is the ideal thing to use for some cases.
<deba5e12>
ok, thanks. is the interface more or less the same as pip?
<mdash>
If you just want to install a single python application, it may already be in nixpkgs
<deba5e12>
i'll take a look, thanks. does nix generally advise against using programming language specific package managers (like cabal, cargo, etc.)?
<mdash>
Generally it wraps them

hi all, I'm a new user having some problems. I'm trying to install ghc-vis (nixos.haskellPackages.ghc-vis). It's failing because of a dependency version problem (transformers library needs to be <5). I tried to install it through an older version in nixos.haskell.packages.ghc763.ghc-vis, and something else crapped out while building ghc + dependencies...

This happens both with my default shell (fish) and with /bin/sh. /bin/sh also doesn't give a prompt or interactive behavior.

I had some problems with fish as default shell
arian_ has quit [(Quit: arian_)]
<DIzFer[m]>
yeah, try using bash as default shell and then, in bash.interactiveshellinit start fish
<boomshroom>
Bash seems to work. Does anyone know why this happens?
<DIzFer[m]>
since fish is not posix, the scripts that set up the shell profile don't work
<vith_nix>
how do i allowUnfree for a package via import <nixos-unstable> {}?
<boomshroom>
Is there a way to have bash exit when its child exits?
<offlinehacker[m]>
boomshroom: use wait
<offlinehacker[m]>
or wait <PID>
<boomshroom>
I guess now the question is why does it work when not in ssh. And also how to modify the scripts to use fish compatible ones when it's selected.

I have a Nix build machine running in a VM, with a large /nix/store with all of the derivations I've built and deployed to various machines over the last few months. Let's say I want to migrate it to a real host running NixOS. Presumably I can just rsync the contents of /nix/store on the VM to the physical host?

Is there an officialy-supported way to do this? nix-copy-closure?

anyway, i have another pretty generic and basic question, if anyone can help: I'm having a bit of trouble building programs on nix. gcc and sbcl have both had trouble finding shared libraries that I know are present on the system. Is there some nice, elegant way of telling compilers where to find these libraries in nix, or do I just need to run locate and point LD_LIBRARY_PATH at them each time?

If I'm adding an authorized key to configuration.nix, do I need to paste the whole thing in, or just the first part. None of the examples that I could find use the full public key.
<boomshroom>
qknight_: It should just be to paste the overlay in your ~/.config/nix/overlays/ folder and rebuild. That said, the overlays in the mailing list are just samples and don't operate on real packages, so you need a package to override first.

I've got a problem where a file that shouldn't be wrapped is being wrapped by wrapGAppsHook. It's causing a problem because the file is supposed to be ran as pure Python.

i seem to be having an unreasonably fussy time trying to get a project to compile with shared libraries. it's a lisp program, and uses libpcap. libpcap is in ~/.nix-profile/lib, and I've set LD_LIBRARY_PATH to point to that directory. the weird thing is that this worked *once*, and then failed when I tried the exact same thing (to the best of my knowledge, even though this makes no sense) again. Any
<deba5e12>
thoughts, #nixos?
<clever>
deba5e12: nix only sets the linker flags up if your using nix-build or nix-shell
<clever>
deba5e12: it will never look in ~/.nix-profile by default
<deba5e12>
even if LD_LIBRARY_PATH=~/.nix-profile/lib?
<clever>
that tells it where to look at runtime, but not where to look at link-time
<deba5e12>
this makes it a bit tricky to use nix for development, but afaik that's its primary purpose. Ah, right. ok, thanks.
<clever>
and there is a lot of other things nix-shell does to help
<deba5e12>
I wasn't sure which one would be in effect when it came to sbcl.
<deba5e12>
(since it's compiling inside a runtime)
<clever>
deba5e12: just run "nix-shell -p libpcap" and then try to compile under that
<deba5e12>
ok, I'll give that another shot.
<clever>
ah, is there a way to save the compile output?
<deba5e12>
nope
<clever>
how often would you have to compile it?
<deba5e12>
well, very frequently, since I tinker with it regularly in an interactive lisp session.
<deba5e12>
i need some way of making .so files available to lisp when lisp is running interactively. this used to be a piece of cake, using cffi, or whatever.
<deba5e12>
i'm sure i'm not the only lisper using nix, so this must be a solved problem.
<clever>
try running the lisp repl inside the above nix-shell and see if that helps
