Re: [Nix-dev] FreeBSD Support

[Nix-dev] FreeBSD Support
I see that FreeBSD is no longer stated as supported. Is this because the nix tools themselves no longer work under FreeBSD or because the packages have fallen into disrepair? /Malcolm ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
Re: [Nix-dev] Dataflow
It's unclear to me what problem your proposal solves. If the source of the issue is the package itself is paralleizing builds (i.e. rebar) then how does making Nix more dataflow solve that? stewart mackenzie writes: >> Maybe I'm wrong, but I don't think the Nix language itself has any idea >> of concurrency as such -- at the manual says >> >>"The Nix expression language is a pure, lazy, functional language." >> >> (https://nixos.org/nix/manual/#ch-expression-language) > > Actually I recall eelco talking about threads in nix.

Re: [Nix-dev] cabal install vs. libgcc_s.so.1 must be installed for pthread_cancel to work
As a bandaid, I have gotten around this in some ocaml packages by using
LD_PRELOAD:
export LD_PRELOAD=$HOME/.nix-profile/lib/libgcc_s.so
This 'solves' the problem for me.

Re: [Nix-dev] Newbie questions
You can use Nix on OS X, however NixOS is an OS, I'm unaware of any overlay for OS X (or how much sense that would make). Myself, I use a Mac mostly for hardware + (once upon a time) a non bad UI. I do everything on my Mac inside a VM running NixOS. This works pretty well for me. If you want to replace OS X with NixOS, I know some people have had success there. For installing Nix on OS X, so you can use nixops to create VMs (if you want to do it that way), you can see this blog post: http://functional-orbitz.blogspot.se/2013/05/setting-up-nixops-on-mac-os-x-with.html This has been turned into a few shell scripts too, by Zef, https://github.com/zefhemel/nixops-mac-setup They are 6+mo old though, so I can't guarantee the directions will work right off the bat.

Re: [Nix-dev] Nix 1.6 released
I am unable to upgrade to 1.6 on one of my machines for an unknown
reason.
I updated my machine by doing 'nixos-rebuild --upgrade switch' and
rebooting.
$ nixos-version
13.09pre5022_71365b7-38d54cf (Aardvark)
$ nix-env --version
nix-env (Nix) 1.5.3
$ which nix-env
/run/current-system/sw/bin/nix-env
$ sudo nix-channel --list
nixos http://nixos.org/releases/nixos/channels/nixos-unstable
$ nix-env -qa '*' | grep -e '^nix'
nix-1.5.3
nix-1.6pre3215_2c1ecf8
nix-generate-from-cpan-1
nixops-1.0.1
nixpkgs-lint-1
Interesting fact: on my other machine that did upgrade properly, the
output of the grep is different:
$ nix-env -qa '*' | grep -e '^nix'
nix-1.5.2
nix-1.5.3pre3141_1b6ee8f
nix-generate-from-cpan-1
$ nix-env --version
nix-env (Nix) 1.6pre3215_2c1ecf8
Any suggestions?

Re: [Nix-dev] Templates
I want to add Riak support to NixOS. The config file is quite large and
can be complex. It also is a supported file type in my Emacs so I get
pretty syntax highlighting. Putting this inside Nix expressions losses
this feature. I think putting config files in Nix expressions is
suboptimal.

Re: [Nix-dev] Templates
I want the same semantics as including a config as a string literal in a nix expression, but I want it to be in its own file, preferably without any nix syntax around it.

[Nix-dev] Templates
This was discussed a little bit in #nixos. The question is: currently it seems that the only option for doing configs in NixOS is by putting a string literal in a nix expression. This can become unweildly for applications with large configurations. Are there other options? /M ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

Re: [Nix-dev] command-not-found can't open db
I just noticed it's trying to open programs.sqlite in per-user/root,
which my user does not have read access to. programs.sqlite does exist
in the per-user dir for my user, I don't know if it should be looking
there or why it isn't.

Re: [Nix-dev] NixOS on Linode
Shea was kind enough to help me out a lot (aka, doing every step then teaching it to me). I have taken what Shea has done and pushed it to the wiki. These instructions have been done at least twice, and I have plans to do it again once I have migrated my Ubuntu Linode to my NixOS one and can reinstall. Sorry if wiping out the previous Wiki page was incorrect, these instructions are more complete and verified, though.

Re: [Nix-dev] NixOS on Linode
Thanks Shea! How do you boot the ISO on Linode. What I did: - Created a small Gentoo disk and a LiveCD disk - Booted into Rescue Mode - Downloaded the http://nixos.org/releases/nixos/latest-iso-minimal-x86_64-linux to the Gentoo disk - dd'd the iso to my LiveCD disk - Modified Configuration so LiveCD is the boot disk, and kernel is pv-grub (x86_64) Then I try to boot and I get a grubdom screen and can't get it to boot. Am I doing it right? Thanks! Once I can get a working Linode I'll push this information back to the wiki. /M s...@shealevy.com writes: > Hi Malcolm, > > I have NixOS running on a linode instance using pv-grub.

Re: [Nix-dev] NixOS on Linode
Thank you for the responses everyone. I'm such a noob at this, I have
some questions.
I'm trying to follow the Rackspace directions, but I'm running into
issues.
1 - I couldn't get anywhere with the Rescue Disk, because I couldn't
install anything on ~. So instead I created a Gentoo partition of 5
gigs, then devoted the remaining room for where I want to install NixOS
2 - I tried to follow the Rackspace directions but I ran into issues.
The farthest I got was nixos-install and it saying it would not install
because '/' was not a real mount point (or something similar, sorry I
don't have the output).
So here is what I think I should be doing, and hopefully someone can
school me:
1 - I need to have a place I can mount the NixOS install ISO
2 - I need to unsquash that filesystem into a dir so it looks like a
running installation iso
3 - I need to chroot into this, then I can install NixOS as if I were
installing while running the installation ISO. In this case I should
mount my destination location to /mnt, modify
/mnt/etc/nixos/configuration.nix and do nixos-install
Unfortunately, at step 3 is where I get an error.
Do I understand the procedure correctly? Am I messing up someplace
obvious?
Thanks!

[Nix-dev] Bad bash in NixOS?
The version of bash in the NixOS I am running (which I think is fairly up to date) has a bug in it where if you have try to tab-expand an env variable it escapes it, so: export FOO=$HOME/bar becomes export FOO=\$HOME/bar This appears to be an acknowledged bug in bash with a patch out[1]. Is this coming to NixOS? Is it here right now and I just am not upgrading properly? /Malcolm [1] http://gnu-bash.2382.n7.nabble.com/bash-tab-variable-expansion-question-td9614.html ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
Re: [Nix-dev] Language-specific package managers
The situations you've described are basically the ones I'm in. Luckily the ocaml package manager I am using just does local installs the packages in the home dir. I actually think I have figured out why it wasn't building packages for me before, and think I can get around it so I can just use the ocaml package manager for fast development and once things become static make real Nix expressions from it. /M Florian Friesdorf writes: > Hi Malcolm, > > Malcolm Matalka writes: >> Thanks for the complete response Marc. >> >> For the mean time, the current solution I'm working on is manually >> converting packages to Nix.

Re: [Nix-dev] Language-specific package managers
Thanks for the complete response Marc. For the mean time, the current solution I'm working on is manually converting packages to Nix. The translation is pretty straight forward and I should be able to write a tool to automatically do it. It's not optimal but I have been able to get all of the packages I care about into my local nixpkgs repo and will submit them to the master repo once I'm satisfied with them. /M Marc Weber writes: > I created > hack-nix for Haskell, which dumps hackage. contains a brute force > dependency solver > > nixpkgs-ruby-overlay [1] which dumps rubyforge (which is quite usable, but > not perfect yet) > nixpkgs-python-overlay [2] which dumps PyPi (experimental, dependency > inforamtion is not complete enough) > does not do backtracking, if dependencies fails its you having to to > tell it "try lib-A version 2.0.0". > > They are special because they all work on a "dump of packages" creating > .nix derivations on the fly whereas cabal2nix creates .nix files very > close to what you find in nixpkgs. > > They all create kind of shell script you can source to augment the > environment variables, so that dependencies are found. > Thus you can have multiple "sets of packages" for different targen > porjects within the same user account without conflicts - however you > always have to load such an environment, eg by > > # run bash with ruby packgaes found in environment "name" > ruby-env-name bash > > Known additional universes: > - perl > - java, scala (ivy, maven, sbt) > - > > There are many ideas and ways to implement such. > Eg for scala/maven/ivy/... one way to think about it would be using the > store as "installation place", but not using much about the nix* tools > otherwise. > > then sbt build would just store everything in store. > Other ways are creating .nix files for a target on the fly - such as > sbt/ivy/mvn create-nix-derivations (which is close to what cabal2nix > does). > > The downside is that you may have to run a tool before you can succeed > with nixos-rebuild-switch, because not everything may be packaged. > > The perfect way would be including a SOT solver in nix, which hasn't > beeen done yet - and which was not favored by Eelco in the past (maybe > for good reason).

[Nix-dev] package aliases
I'm creating a series of packages where one of them is just an alias for installing the entire suite, so it doesn't have any build script or src. What is the appropriate way to accomplish this?

Re: [Nix-dev] fetchgit - why sha256 protection?
Could fetchgit handle that on its own though?

[Nix-dev] Curl certs
I'm trying to create a package that, as part of its make, downloads some stuff through curl. Most work but one in particular is failing due to certificates (see below). This works if I do it on the command line. I tried adding 'cacert' to my buildInputs and parameters, but that didn't seem to work. What is the correct solution? Still quite new to Nix so apologies if this is a common question, I didn't find anything in my google searches.

If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. make[2]: *** [dose3-3.1.2.tar.gz] Error 60 ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
[Nix-dev] Language-specific package managers
Hello! I am wondering what the Nix view on language specific package managers is. They seem at odds with the goals of Nix. I see there is a tool for converting cabal packages to Nix packages, is the idea to have little translation apps for all language package manager types?
