But one of them is being a pain: JLinkGDBServer: relocation error: JLinkGDBServer: symbol , version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference The collective wisdom of the web suggests this might have something to do with the binary using symbols from libc that are not in my version of glibc.

I find that writing a default.nix file or a shell.nix file for each project that I work on gives me the best results. As an example, below are some files that I've hacked up. I don't work with Ruby that often anymore so my motivation to make these files better isn't really there. First, a function that uses its arguments to build a package/environment for each application that I work on: https://github.com/pjones/nix-utils/blob/master/lib/ruby/default.nix And here is an example application using that function: https://github.com/pjones/nix-utils/blob/master/envs/rfa/cltc-phoenix.nix The way I use this is by running `nix-shell`, giving it the above file, while in the directory of the application. It drops me into a shell that has everything I need to work on a Ruby/Rails application. -- Peter Jones, Founder, Devalot.com Defending the honor of good code ___ nix-dev mailing list nix-dev@lists.science.uu.nl https://mailman.science.uu.nl/mailman/listinfo/nix-dev

[Nix-dev] Managing /home during system activation
I'd like to manage files in my home directory during system activation. Sort of like nix-home[1] but during activation so NixOps can also deploy things such as my shell configuration. I have an idea, and I'm wondering how terrible it is. Based on the way etc activation works, I would build a directory in the nix store and fill it with symlinks to other parts of the store: /nix/store/xxx-home-pjones/.zshrc -> /nix/store/xxx-zshrc/zshrc Then, set up a UnionFS mount so that /nix/store/xxx-home-pjones gets overlaid on top of /home/pjones. This means I don't have to search through /home looking for links to an old generation to deactivate it, and rolling back just mounts a previous generation on top of /home. So, how bad is this idea?

Re: [Nix-dev] nix-shell for a custom haskell library
Dmitry Malikov malikov@gmail.com writes:
I'm trying to setup a development environment for a custom haskell library
basing on a tutorial by Oliver Charles
(http://wiki.ocharles.org.uk/Nix).
FWIW I've been playing with Nix and Haskell a lot lately trying to come
up with the perfect development environment. This is what I have so
far. Everything below is done with a recent copy of nixpkgs.
I have a shell function called nix-hs-build that does the following:
# Create a default.nix for the Haskell project in $PWD:
nix-shell -p haskellPackages.cabal2nix \
--command cabal2nix $PWD $@ default.nix
# Build the project:
nix-hs-shell --command $(which hsbuild.sh) $@
The contents of hsbuild.sh can be found here:
https://gist.github.com/pjones/7a6023d3567ff2ed49bf
The `nix-hs-shell` command is another shell function that just runs
nix-shell with cabal-install and hlint in the environment so that
hsbuild.sh can work. Here are the details:
function nix-hs-shell () {
override=~/.nixpkgs/envs/dev/haskell-cabal.nix
nix-shell -I pwd=$PWD --pure $@ $override
}
Where haskell-cabal.nix contains:
{ nixpkgs ? import nixpkgs {}
, compiler ? ghc7101
}:
let
pkgs = nixpkgs.pkgs;
ghc = pkgs.haskell.packages.${compiler};
f= import pwd;
drv = ghc.callPackage f {};
in
(pkgs.haskell.lib.addBuildTools drv [
ghc.cabal-install
ghc.hlint
]).env
With those pieces I can just run `nix-hs-build` without having to create
any sort of *.nix file by hand. If I change the project's cabal file
and run `nix-hs-build` it will work since it generates the default.nix
again. I can also change compilers with a flag:
nix-hs-build --compiler ghc784
How to get Network.EngineIO available inside a nix-shell in this case?
Using my setup above, the library would be installed in ./dist

The important thing is to make sure that your X server is running on _the same virtual terminal_ your logind session was opened on, otherwise you won’t get permissions to access hardware.

It appears that if you have a ~/.config/pulse/default.pa file then pulseaudio will not read /etc/pulse/default.pa. This wasn't the case in previous versions. Even an empty ~/.config/pulse/default.pa file will prevent pulseaudio from reading the one in /etc and thus it will start with no cards. Sounds like a bug in pulseaudio. -- Peter Jones, Founder, Devalot.com Defending the honor of good code ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
Re: [Nix-dev] Pulseaudio broken in 14.12: Daemon already running

Running it under my user account somehow prevents pulseaudio from seeing any of the sound cards. I did have my user account in the audio group. I've since removed it after reading some documentation, rebooted, and still no sound cards detected by pulseaudio. Using strace, I don't see pulseaudio failing to open any files or even trying to access /dev/snd/*. I do see several errors coming from setrlimit though. What's the next step in debugging this? -- Peter Jones, Founder, Devalot.com Defending the honor of good code ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

Kirill Elagin kirela...@gmail.com writes: What exactly do you mean by “disabling” pulseaudio? Do you have a system-wide instance of pulseaudio running (e.g. by setting `pulseAudio.systemWide = true` in the configuration.nix)? If yes, then do you have any good reasons for doing so? If no, then disable the system-wide instance. By disable I meant `hardware.pulseaudio.enable = false;'. Normally, there is exactly one instance of pulseaudio per user and it is spawned automatically (to be precise, it is spawned automatically iff it is not already running; and most likely your DE starts one during initialisation). I'm only running the one (user) instance and don't use a DE so one isn't started when I log in. When I start an audio application pulseaudio is started automatically. The problem seems to be that pulseaudio is started even if another one is running. Clients can't seem to detect the running pulseaudio thus they start a new daemon which immediately dies after seeing an existing PID file. How do clients check for a running pulseaudio daemon? I'm wondering if that process is broken. -- Peter Jones, Founder, Devalot.com Defending the honor of good code ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev

[Nix-dev] Pulseaudio broken in 14.12: Daemon already running
Pulseaudio stopped working for me after upgrading to 14.12. It seems that all PA clients start their own server, which eventually fails because the pulseaudio daemon is already running. For example, if I kill pulseaudio and then start it by hand with -vvv, I can see it start correctly and write its PID into a file. Then, if I run anything that needs to access pulse, like speaker-test, alsamixer, pavucontrol, etc., I can see in journalctl that another instance of pulseaudio is started and then dies with the error Daemon already running. The client usually dies with connection refused. I've turned off autospawning, and that doesn't change anything. Disabling pulseaudio and rebooting gives me sound again. Any idea why each client is trying to start their own pulseaudio daemon? -- Peter Jones, Founder, Devalot.com Defending the honor of good code ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
[Nix-dev] Hard-coded dlload paths in .so [was: Nix expression for closed-source scanner driver]

After using `nix-env' to install the package I'm still not able to see my scanner in the list produced by `scanimage -L' or `sane-find-scanner'. Here's the expression (WIP): https://github.com/pjones/nixpkgs/blob/pkg/brother/pkgs/misc/drivers/brother/dsseries.nix Something interesting to note is that device files for the scanner show up in /dev/bsg/ instead of the usual /dev/sg*. I think that has something to do with the scanner being detected as a disk. I did have this working under Debian before switching to NixOS. I also still have a Debian install if I need to test anything or figure out what's going on. Any hint/tips would be appreciated. Thanks. Maybe you must patchelf some binaries? See if this finds something that points to (nonexisting) /usr/... or similar: find $out | while read f; do patchelf --print-rpath $f; done None of the .so files in the binary package have an RPATH set. I was able to use strace and strings to discover that the main .so for the scanner driver tries to dlload two other .so files using hard-coded paths. Can I alter the strings in the .so or do I need to make some sort of wrapper that intercepts the dlload calls and loads the correct libraries? If the latter, is there an example somewhere I can use as a guide? -- Peter Jones, Founder, Devalot.com Defending the honor of good code ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
