When trying to use gccCrossStageStatic with a crossSystem, nix complains about an unknown libc. It says the same thing regardless of omitting it or setting it to null.
<boomshroom>
Hello?
<sphalerite>
boomshroom: hello
<boomshroom>
I'm back from my laptop with homework printed.
<boomshroom>
The channel seems a bit quieter than when I left.
<sphalerite>
CapsAdmin: are you Elias Hogstvedt?
<sphalerite>
(because your question sounds quite similar to some emails on the mailing list recently)
<boomshroom>
How do I prevent gccCrossStageStatic from using and building a libc?
<CapsAdmin>
sphalerite, yes
<CapsAdmin>
my question now or on the mailing list?
<sphalerite>
CapsAdmin: it seems your main concern is getting rid of nix after using it?
<CapsAdmin>
yes, that's my concern right now
<CapsAdmin>
well
<sphalerite>
CapsAdmin: a regular single-user installation can be cleanly wiped out by removing /nix and ~/.nix-*. That should be all it takes, so going with the well-trodden path of the standard single-user installation is probably your best option
<CapsAdmin>
sphalerite, when i posted on the mailing list it was just a detail (didn't want to clutter someones system) but now there's a different issue where the binaries from nix depend on nix (for obvious reasons)
<CapsAdmin>
so right now i'm wondering how to deal with this
<CapsAdmin>
how can i take freetype for instance out of nix and make it independent
<CapsAdmin>
maybe, thanks
<sphalerite>
there's no trivial way to do it because that's not how nix is designed to work

<sphalerite>
so what you'll want is probably something like nix-bundle, or using nix to build docker images, or something
<sphalerite>
but none of those are really as elegant as just using nix properly
<CapsAdmin>
but i want this for libraries, not executables
<CapsAdmin>
sphalerite, i was thinknig of just using patchelf if possible
<sphalerite>
you could do that but it's a massive fuss and kind of defeats the point of using nix
<sphalerite>
you might as well just use static libraries with a more traditional package manager
<TimePath>
It should be easier going in reverse though, right?
<TimePath>
If there are any store references detected, you missed a thing
<CapsAdmin>
sphalerite, what i thought was useful about nix initially was just that it was a portable package manager with most of the packages i want available
<CapsAdmin>
i didn't think of how it works necessarily

If I want to build a compiler that runs on my local platform and builds for a foreign target, is gccCrossStageStatic the right thing to do?
yegortimoshenko has joined #nixos
jb55 has joined #nixos
<CapsAdmin>
sphalerite, i think this would be an issue regardless, ultimately i want my application to be portable
<CapsAdmin>
at least nix seems very clear about dependencies
<sphalerite>
CapsAdmin: the best thing to do for portability is not to bother with binary distributions
<sphalerite>
CapsAdmin: just make a source tarball and package it for your distro(s) of choice, and let other people take care of packaging it for other distros.
<CapsAdmin>
well maybe i can rely on nix to take care of binaries for me
<CapsAdmin>
hmmm
<sphalerite>
CapsAdmin: single binary distributions are mired with problems, at the latest when you get to paradigm-changing packaging systems like nix. Just go with source. It works for most software.
<CapsAdmin>
the problem is that i'm not maintaining the source
<CapsAdmin>
i mean, my source is luajit so that's fine
<CapsAdmin>
but i don't maintain freetype for instance
<sphalerite>
CapsAdmin: if you use something like nix-bundle you're redistributing the libraries your application depends on — along with any bugs in them — and making it harder to replace them. And it increases the size significantly

Looking at nixpkgs reveals that gccCrossStageStatic calls out to libcCrossChooser which panics when given anything other than the 4 it expects. This is a problem for me because I don't want a libc.
<boomshroom>
I think that's why I did the roundabout manner I did before.
<sphalerite>
CapsAdmin: so what you're making is a binary distribution of luajit?

<CapsAdmin>
i just think it's fun lol
<CapsAdmin>
i want to try and do it properly
<simpson>
"properly" in this case involves embracing Nix.
<CapsAdmin>
i guess
<CapsAdmin>
first i want to try and resolve dependencies with ldd
<CapsAdmin>
maybe the best way is to ask users to install nix to get the binaries needed

maybe i can share with some friends
<simpson>
CapsAdmin: I don't have friends, but if I want people to use my software these days, I check in a shell.nix. Nix is getting much more popular.
<CapsAdmin>
ok so with the help of ldd, i can literally copy the dependencies of the shared library flat into my binary directory and export LD_LIBRARY_PATH=mybindir
silver_ is now known as silver
<CapsAdmin>
that does seem to work (strace says it loads from mybindir rather than nix)
<TimePath>
I've dealt with a project that had a dist script like that to copy all transitive shared libraries to the output
<clever>
CapsAdmin: nixos also does similar, to make the initrd
<TimePath>
It worked mostly, some of them required additional files at runtime though

<judson>
CapsAdmin, what I'm understanding is that you're working on a hobby project game, and concerned about how to package and distribute it once you get it going?
<judson>
Games tend to be messy in terms of the dependencies and distribution. The former is what made me think of nix-shell
<judson>
Long term, you'll have an easier time if you can get a shell.nix to set up your working environment - then you can crib and hack on your setup for the next project.
<judson>
But, maybe we're not there yet, and you're happier to whack libraries around by hand.
<judson>
Anywhere but games, I'd advise against that, but I appreciate how weird gamedev can be.
<CapsAdmin>
judson, i think my goal is just to refactor my build system. use something that's proven to work

i thiknk relying on nix is a bit scary right now (takes too long to setup initially) :)
<gchristensen>
iqubic: it evaluates the nix expression, which creates a number of derivation files (.drv) in the nix store, and then Realizes those derivations in to store paths (ie: runs the build commands to follow the instructions to build the software)
<infinisil>
iqubic: please read the nix pills for such basic questions

I was able to (mostly) build a arm-none-eabi binutils, but then it complains that `arm-none-eabi-ld` doesn't exist. It appears to have an `ld` and a help command makes it look like it's actually and x86 linker/assembler.

CapsAdmin: oh, you also dont even need `-I${lib.getDev assimp}`, adding assimp to the buildInputs handles that for you
<CapsAdmin>
clever, getDev returns the root directory of assimp
<CapsAdmin>
i still have to /include
<clever>
yeah
<CapsAdmin>
oh
<CapsAdmin>
or lib
<clever>
but the stdenv already adds every buildInput to the -I path for you
<CapsAdmin>
oh
<CapsAdmin>
so just include/ and lib/ then?
<clever>
no need to play with -I
<clever>
but for dlopen(), you will probably want to symlink the libraries, not copy them
<CapsAdmin>
even when calling gcc manually?
<clever>
yeah
<clever>
your not calling gcc, your calling a bash script with the name `gcc`
<clever>
and that bash script obeys the nix options
<clever>
oh
<clever>
also, dont put gcc into the buildInputs
<clever>
the stdenv comes with gcc

also try doing a pwd ; ls -ltrh in the buildPhase, you can likely use a shorter path

its just simpler and more stable to use the tools that already do everything for you

What does the first line of the derivation do?
<iqubic>
{ stdenv, fetchurl }:
<iqubic>
is that just the dependecies needed to run the derivation?
<clever>
iqubic: that defines a nix function, that expects 2 arguments, stdenv and fetchurl
<iqubic>
Is that separate from the buildInputs?
<TimePath>
the expression in that file is a function
<TimePath>
nix will auto-call package functions with required arguments
<clever>
that just brings the variables into scope, so the buildInputs can then refer to them
<iqubic>
If I put something into my build inputs, I also need them in derivation function's inputs?
<bulldog>
clever: so I want to use the overlay in nixpkgs-mozilla (https://github.com/mozilla/nixpkgs-mozilla) on my config. Does this mean I only have to somehow add the contents of firefox-overlay.nix into nixpkgs.overlay?

iqubic: if doCheck is set to true, it runs the checkPhase

What does the checkPhase do?

iqubic: the default checkPhase is on line 994, but you can also replace it by doing checkPhase = '' .... ';
<bulldog>
clever: ooo okay, was thinking something like that. Might use a local clone of the repo for security. Let me see if I can get it to work. Thanks!

bulldog: you can specify the sha256 in the fetchFromGitHub
<iqubic>
I assume I don't need the checkPhase, because I have no idea what it does.
<clever>
iqubic: the default checkPhase will basically just run `make check`
<bulldog>
clever: but then it breaks if contents change!
<clever>
but you can set checkTarget to change that
<clever>
bulldog: also specify a specific revision
<bulldog>
oooh, I see
<clever>
bulldog: then the contents can only change if your being haxed
<iqubic>
yeah, I don't need that for my ninja based build.
<clever>
and you want it to fail then :P
stepcut has quit [Remote host closed the connection]

so this is very strange, suddenly my $NIX_PATH is refusing to be recognized by nix-shell: `error: file ‘nixpkgs’ was not found in the Nix search path (add it using $NIX_PATH or -I)`
<clever>
just rev alone is enough to lock that in
<clever>
taohansen: what does `nix-instantiate --find-file nixpkgs` say?
<taohansen>
same error as above
<clever>
taohansen: and what is the value of $NIX_PATH?
<iqubic>
So, is it possible to install FMOD on nixos?
<iqubic>
Or at least use it as a library?
<taohansen>
clever: it was correctly underneath /nix/ but now it's this horrific spaghetti output. hold on a minute, let me get my bearings
<iqubic>
Can I use that as a library in a derivation?
<iqubic>
I need fmod for my buildInputs.
<clever>
iqubic: somebody hacked it in, and never added a top-level fmod, so its been in nixpkgs for over a year, but its just not visible
<clever>
you need to callPackage it, like like 8 did
<clever>
with the correct relative path
<bulldog>
clever: question, still not very familiar with nix. Why is this part necessary: `(import "${(import <nixpkgs> { config={}; overlays=[]; })`? Isn't there a way to express something like `nixpkgs.overlay += (import fetchFromGithub{...}/firefox-overlay.nix)`?
<clever>
callPackage <nixpkgs/pkgs/games/zandronum/fmod.nix> {} is one way
<iqubic>
I see.
<clever>
bulldog: the value of fetchFromGitHub relies on having pkgs loaded
<clever>
bulldog: and pkgs relies on the value of overlays being loaded
<iqubic>
So I shouldn't put fmod into the inputs to the derivation function, and instead retrieve it that way?
<clever>
and now you have infinite recursion
<clever>
iqubic: yeah, because the last guy to add it, did it wrong
<iqubic>
Oh, I see.
<iqubic>
Will that ever get fixed?
<taohansen>
clever: `bash: /home/taohansen/.nix-defexpr/channels/nixpkgs:nixpkgs=/home/taohansen/.nix-defexpr/channels/nixpkgs: No such file or directory`
<clever>
soembody can file an issue to fix it
<taohansen>
yet i'm looking at it right in front of me
<iqubic>
I think I might do that.
<taohansen>
the path is correct
<clever>
taohansen: ls -lh /home/taohansen/.nix-defexpr/channels/nixpkgs
<clever>
taohansen: that is a list of several paths, you cant just ls $NIX_PATH

I guess there is a way to get rid of the absolute path in the -i command?! would love to see something like "versioning". let's say ourapplication 2.0 uses path xyz and we can install it by nix-env ourapplication-2.0 or somethine like that

I'm running a fresh NixOS installation (for the first time, wuhuu!). Unfortunately the terminal seems to be broken to the point where I can't edit files with nano. Which is kind of a showstopper. Whenever I run something like clear of reset I get the message "'linux': unkown terminal type". The reason seems to be that in the terminfo database there are entries for lowercase letters there are "*~nix~case~hack~1" entries which seem too n

setting TERM to dumb fixes the backspace issue but nano is still broken (no content, only controlls on the bottom)

Hello

I'm having a very weird issue that's to me stumped: when I try to run some programs (eg. watchman, I'm getting this error: /nix.store/.../libstdc++.so.6: version `GLIBCXX_3.4.22' not found)
<tilpner>
winem_ - Does your /etc/nix/nix.conf have "build-use-sandbox = true"?
<ndrei>
This is happening for a few packages, watchman is just the last one I've tried
<ndrei>
well.. I don't remember.. I mean, /nix/store is read-only anyway, so I couldn't of messed with that
<ndrei>
I'm guessing it's something that's mutable in the system that got corrupted somehow.. but what could that be? and how could that involve libstdc++?
<ndrei>
I've tried switching channels from unstable to stable, system version from 18.03 to 17.09.. nothing

Also, perhaps related, some binaries I've tried running, like Mancy (a Node REPL), give me a "file not found error" when I try to run them

tilpner: I guess it's just nix-build ... --option build-use-sandbox true to make sure that sandboxing is used. is that correct?
<tilpner>
winem_ - Anyway, IIRC non-NixOS builds don't sandbox by default. You could try enabling it for just one build, but it'd be a good thing to have permanently
<winem_>
totally agree regarding the permanent solution
<ndrei>
tilpner: :X ... nevermind... I found it.. I had LD_LIBRARY_PATH set in a shell init file... :/... Thank you :)..
<tilpner>
ndrei - That's not related. Most foreign (not compiled/patched for NixOS) binaries use the wrong interpreter
coot has joined #nixos
<tilpner>
ndrei - You can use patchelf to set the interpreter, or steam-run for a quick escape-hatch to run them in an FHS-compliant environment
<tilpner>
ndrei - (The "file not found" is not related. LD_LIBRARY_PATH of course is)
<ndrei>
tilpner: yeah, I was expecting that.. but since the issue started manifesting about the same time and I was getting desparate... and now I remember, it was because of that problem that I've tried setting LD_LIBRARY_PATH :/

I'm so happy I found it! I was almost going to reinstall the whole thing (well, since this is Nix, not such a big deal) :)

I've submitted a PR for a new package where I used a way of specifying the version which isn't used widely in nixpkgs AFAIK and which I suspected might raise some eyebrows but I think it has some concrete advantages and would like some more input on the idea in general.
<nixy>
I was experiencing similar terminfo issues when running the vagrant NixOS box (which was freshly minted)
<sphalerite>
The idea is that rather than having a let binding or passing a rec set to stdenv.mkDerivation, we make the version string and source hash arguments to the function to make overriding the version a lot simpler. See https://github.com/NixOS/nixpkgs/pull/34275#discussion_r164206558

nixpkgs/master 314fb3d Francesco Gazzetta: twemoji-color-font: init at 1.3
<tilpner>
sphalerite - It's fairly innocuous in your case, but it's dangerous if it becomes convention. ncurses takes an argument "unicdoe", and if you happen to overlay that onto your local nixpkgs, it will break with unhelpful errors. It will supply whatever you overlayed as unicode to ncurses, which expects a bool there
<sphalerite_>
also -- does anyone have a nice way of finding the "dead leaves" in the dependency tree? I have while read path ; do n=$(nix-store -q --referrers $path | wc -l) ; [[ $n == 0 ]] && echo $path ; done < <(nix-store --gc --print-dead)
<arst>
but when I do $ nix-env -qaP .*qt5.*, I don't get qt5.full

<sphalerite>
tilpner: right, fair enough. And do you have a potential better idea for how to do this?
<symphorien>
sphalerite: what do you mean by dead leaves ?
<tilpner>
sphalerite - A while ago I proposed fixing this issue gradually, converting every package into two stages of loading, one for dependencies, the next set for configuration. It's a lot of effort though, and nobody wanted to discuss it further
<sphalerite>
symphorien: those dead paths that aren't depended on by anything else. They're a fairly useful indication of what I might want to keep around or upload to my binary cache before GCing on my slow machine that doesn't have much space
<tilpner>
sphalerite - A workaround would be to clearly mark them as configuration arguments. unicode -> supportUnicode, vanilla -> useVanilla
<arst>
If I knew anything about it I'd discuss it further sphalerite <3

Oh I mea tilpner
<tilpner>
sphalerite - In your case, srcVersion and srcSha256 maybe? Kind of ugly, yes...

<tilpner>
arst - What do you mean?
<tilpner>
sphalerite - I'm not sold on it. I think I'd rather have otter-browser.overrideAttrs (o: { src = o.src.override { rev = ...; sha256 = ...; }; }) (requires makeOverridable fetchFromGitHub)

Arguably allowing them to be used from the outside encourages more tight coupling, but at the same time I don't think there's much in nixpkgs that isn't tightly coupled. Between tight coupling and better potential for reuse (=> less code) and tight coupling and lots of copying and pasting…

looked very promising. I created my own default.nix, and at first glance, it seems to work. But I have troubles getting the right gcc (5, not 6) to work.
iqubic has joined #nixos
jedai has quit [Ping timeout: 252 seconds]
<deets>
the gcc in the path is 6.4, probably pulled in through some dependency.
dbe_ has quit [Ping timeout: 240 seconds]
<deets>
but I would like to "set-alternative" the gcc5
<tilpner>
Try let stdenv = gcc5.stdenv; in ...
<sphalerite>
^
<iqubic>
What does the "rev = ..." do in a fetchFromGitHub do?
<sphalerite>
stdenv includes GCC, so that'll be where it comes from
<tilpner>
iqubic - Sets the revision/commit/tag
jedai42 has quit [Ping timeout: 252 seconds]
<sphalerite>
iqubic: specifies the revision to fetch. That can be a branch name (bad, since it changes over time), a tag name (good because it's fixed and meaningful) or a commit hash (OK because it's fixed but not meaningful)
<tilpner>
deets - Try using gcc5.stdenv instead of stdenv
<sphalerite>
deets: as tilpner said, use gcc5.stdenv either with a let or just replace stdenv with gcc5.stdenv in your expression
<sphalerite>
Argh, just too slow
<sphalerite>
iqubic: I think it fails
<djahandarie>
Does anyone have a pointer to what the latest thinking is on how to integrate .nix files from projects repositories into nixpkgs?
<sphalerite>

sphalerite: I will try.

<deets>
me got gcc-5.5. now here is to hoping that it fixes my cross-tool-bug, but that's not nix problem. thanks a million!
<tilpner>
djahandarie - IIRC some people add the repos to nix-channel, then import <name-of-repo>
<iqubic>
How do I change the source directory of a derivation?
<sphalerite>
djahandarie: I think the typical approach is "don't". I think it's preferred to maintain the "canonical" expression in nixpkgs and refer to that from the in-project expression. Not sure though
<iqubic>
I'm fetching a thing from GitHub, and the makefiles aren't in the top level directory, but in ./unix
<tilpner>
sphalerite - I pin repos like nixdiff or riot-electron, it works okay
shabius has quit [Quit: Leaving]
<tilpner>
sphalerite - Importing them is easier than syncing their default.nix to local pkgs
<djahandarie>
tilpner, sorry, question was unclear. If we expect nix to get really popular, and for developers to use it while actually developing their project, what are the latest thoughts on how to integrate those expressions into nixpkgs?
<sphalerite>
iqubic: I'd do something like preConfigure = "cd unix"; I think
<taohansen>
so i made a ridiculously simple derivation in nix-repl that just runs a shell script that calls typescript to compile a typescript file into javascript. i get a `<<lamba>>` return. how do i test that it runs successfully? here's a gist: https://gist.github.com/d7f791ef6c50a1a5fdbce2b5b3855b1a
<iqubic>
sphalerite: I thought there was a way to do "sourceDir = /unix" or something like that.
<taohansen>
is this correct practice for building up Nix things? using the REPL? i don't like that it makes me start over from bottom-up when i type something incorrectly. also there's no colorized output, linting or pretty-printing of any kind.
<sphalerite>
Tao Hansen: callPackage it. Note that this won't work since you don't have tsc available in the build environment
<tilpner>
djahandarie - I don't have statistics, I was only mentioning one option. I'm not aware of a popular/preferred way, currently
<sphalerite>
Tao Hansen: you may want to have a look at the nix pills for an in-depth introduction to writing expressions
<djahandarie>
sphalerite, but the nix expression is often in-lock with a given code revision. I'm using a function from a new dependecy, so I add that dependency to my nix expression. I and the rest of the team develop with nix, so we naturally keep the nix expression in source control. Since it's basically the canonical nix expression, it seems odd to ignore it entirely in nixpkgs.

okay, Nix-pill reading time. i wish the English in these articles was a little more proofed. some of the language he uses doesn't make any sense.

gilligan_: you need to add iana-etc to the contents of the docker image, line 29 of my example

The strange thing is that it does build without gst-python, it only fails at runtime. But with gst-python as a propogated buildinput it writes this last message which doesn't really make sense

LnL: not yet! but I primarily use vim built .. from my research branch. Similar but some deps may be a bit older than what is in latest nixpkgs. So it quite possibly is slightly different :).

rcshm has quit [Read error: Connection reset by peer]
<MichaelRaskin>
I think I get messages on the screen relatively late into boot.
<sphalerite_>
MichaelRaskin: but it does work fine with the same kernel without an initramfs. I don't know what's going on exactly in here but somehow something along the boot chain (AFAIU it's u-boot -> depthcharge -> linux) isn't liking the initramfs
<MichaelRaskin>
Hm.

there's certainly no EFI involved :)

ssj71: I can run powercut without having jack running. any idea why tilpner can't?

used jalv 1.6.0
<Drakeson>
[General question about upstread->nixos updates...] When a nixpkg in git shows a new version has become available, does that usually mean a nix-channel --update && nixos-rebuild <proper verb> would pick it up? Or there is an extra step happening that I am missing here?
* magnetophon
too
<ssj71>
magnetophon: could he not run it or did it just not have a GUI?
* tilpner
.oO( Why would anyone block a pastebin... )
<ssj71>
tilpner: our MIS department is pretty obtuse, they just block most IPs from outside of US
<tilpner>
That sounds annoying
<nixer>
try pastebin.com
<Drakeson>
There has been "hacks" and "leaks" published only in pastebin
CapsAdmin has joined #nixos
<ssj71>
but yeah that message looks like no jack binary is found
<nixer>
Does anyone know where "nix-env -i" store the added package names? They don't seem to go into ~/.nixpkgs/config.nix...
<Drakeson>
So, I can see why some IT person might have been requested to block pastebin.
<Drakeson>
tilpner: what is the relationship between nixos/nixpkgs and nixos/nixpkgs-channels? Is the former the pre-branch of the latter?
<ssj71>
pastebin.com loads fine
<ssj71>
but anyway, fighting with MIS is always a loosing battle
<ssj71>
losing
<tilpner>
Drakeson - Yes, nixpkgs is what Hydra tests and greenlights for distribution as a channel. They are then mirrored to nixpkgs-channels
<Drakeson>
haha, a loosing battle sounds disgusting
<ssj71>
lol
<magnetophon>
nixer: you know about nix-env -q, right?
<sphalerite_>
nixer: in the manifest in the resulting profile
<Drakeson>
And the process is fully automatic, right? So, say, if I don't see Firefox 58.0 in the nixos-unstable channel, that would mean some tests are stuck at red? Any idea where I can look at the tests?
<ssj71>
magnetophon: well I thank you for your patience. I'm afraid its going to require a fair bit more still before we figure this out. I'll work toward getting a debian install over the weekend and see if I can reproduce it there, but it may not happen yet
<sphalerite_>
Drakeson: hydra.nixos.org
<magnetophon>
ssj71: thank you too!!! and tilpner too
puckipedia has joined #nixos
<Drakeson>
Thanks
<ssj71>
yeah thanks tilpner
<tilpner>
Good luck with that. You could still wait around and see if someone with jack will test your thing :)
<Drakeson>
What is the relationship between the following channels: nixos-unstable and nix-unstable ?
<tilpner>
Drakeson - There is no channel nix-unstable
<magnetophon>
tilpner: I'll be here
<Drakeson>
nixpkg-unstable then?
<Drakeson>
or nixpkgs-unstable perhaps?
<tilpner>
Drakeson - If you mean nixpkgs-unstable, that's a channel without NixOS-specific tests, so it advances quicker
<nixer>
magnetophon: nix-env --query does not seem to display this info
<tilpner>
(And get the entrypoint to tests because I can't navigate Hydra)
<nixer>
magnetophon: its possible to retrieve derivations associated with current user/profile, however it does not deduct to where they are stored as configuration entries.
<nixer>
magnetophon: thank you, I wanted to get more physical location of where they are stored/associated with current profile.
<nixer>
magnetophon: it looks like they are added into profile manifest. I assumed nix-env automatically adds them into ~/.nixpkgs/config.nix, but it looks now that that file is reserved only for manual user input.

What kind of testing goes from nixpkgs-unstable -> nixos-unstable?
<Drakeson>
Or rather, are any kind of tests run on nixpkgs-unstable at all?
<tilpner>
You do not want to run NixOS from nixpkgs-unstable, it may garbage-collect your collect or make your system unbootable
<tilpner>
Uhh, typing
* tilpner
sleeps
<Drakeson>
oh, I most certainly don't want to "switch" to nixpkgs-unstable
