<ng0>funtoo is more like a varation from gentoo, as it varies so much from gentoo that gentoo itself decided not to give support to it, probably like archlinux and some of its deriviates.

<ng0>well, same text.

<sandro_>I've discovered my trouble: my hdd-usb gives to me errors; i try a "zero-fill" .... but i think that i must change it :|

<sandro_>Sorry :(

<janneke>morning Guix!

<rekado>Hi Guix!

<rekado>on one of my GuixSD machines the network device is disabled on boot.

<rekado>wicd doesn't seem to be able to enable it automatically so I need to run "ip link set ens2 up" manually and start dhclient for the device.

<rekado>is there a way to enable the network device automatically?

<rekado>a new R version is out. And a new version of the bioconductor repository, so I'll update the importer to fetch from the latest version and update the individual bioconductor R packages.

<foobarry>did a guix pull and got this errro

<foobarry> http://pastebin.com/4DSpBbrV

<foobarry>worked 2nd time but what was the error all about?

<civodul>Hello Guix!

<z0d>hi

<cow_2001><3

<cow_2001>this is why you are needed http://www.pcworld.com/article/2845072/ubuntu-owncloud-and-a-hidden-dark-side-of-linux-software-repositories.html

<cow_2001>(among other reasons)

<rekado>hmm, latest R has a test failure on my system. Probably timezone related.

<rekado>on Guix R 3.3.0 this gives the wrong value:

<rekado>strptime("1941/01/01", "%Y/%m/%d", tz="CET")

<rekado>I get the time zone "CET", but it should be "CEST"

<rekado>I don't see this on another system with R 3.3.0 installed from source.

<rekado>strptime is provided by glibc, I think.

<rekado>I tried to verify that this is a problem with our strptime by using it with Guile, but Guile's strptime doesn't set the time zone.

<sneek>So noted.

<rekado>sneek forget I tried to verify that this

<sneek>Consider it forgotten.

<rekado>sneek: silly bot!

<rekado>sneek: botsnack

<sneek>:)

<civodul>:-)

<civodul>rekado: in the build environment, the timezone is always the same

<civodul>but here the test relies on timezone data, right?

<rekado>I disabled the tests and created an ad-hoc environment with the new R.

<rekado>I can reproduce the behaviour there, too.

<civodul>you probably need to add tzdata as an input and set TZDIR

<civodul>i think there are a few packages that do that

<rekado>thanks for the hint. I'll try that.

<civodul>so you were at OTS yesterday?

<rekado>yes

<civodul>cool!

<civodul>how did it work out?

<rekado>talked to lots of people who were curious about Guix.

<rekado>some were surprised this is a GNU project.

<civodul>oh?

<rekado>seems like GNU is not generally associated with "cool" stuff.

<civodul>heh, interesting

<rekado>aside from one person who started every sentence with "yeah, but ..." (and then went on to talk about why everything we do is useless) it was very well received.

<civodul>good

<rekado>many wanted to see it in action, so I had lots of opportunities to demo it.

<civodul>you managed to print the glorious posters?

<civodul>nice

<rekado>yes!

<civodul>\\o/

<rekado>I actually found the plotter room the day before yesterday at 9pm.

<civodul>woow

<civodul>just in time

<rekado>I was afraid I wouldn't be able to access it; that was my only chance to actually get it printed. Yesterday it started at 8am and since it's a holiday I wouldn't have been able to get it printed anywhere else.

<rekado>very happy

<cow_2001>i still get this "failed to install locale"

<cow_2001>GUIX_LOCPATH points where it should

<civodul>rekado: well, congrats, you must have rushed quite a bit!

<civodul>we should put the PDF on the web site

<civodul>cow_2001: how did you install Guix? using the binary tarball?

<cow_2001>yes

<civodul>is there a locale package installed, as shown at https://www.gnu.org/software/guix/manual/html_node/Application-Setup.html ?

<cow_2001>yes, /gnu/store/dcqdfyal290awy1lwb6sxzs8sg0wr99h-glibc-locales-2.22

<cow_2001>it doesn't *always* show up, for now just when installing packages

<civodul>weird

<cow_2001> https://mirror.hydra.gnu.org/nar/q99acjwx5haj54gcj0l9pv6bbh7pdgv9-mesa-11.0.9 555KiB/s 00:58 | 31.6MiB transferred

<cow_2001>warning: failed to install locale: Invalid argument

<cow_2001>i don't know if it matters

<civodul>cow_2001: it's harmless

<civodul>note that this one comes from guix-daemon

<civodul>so you need to set GUIX_LOCPATH in guix-daemon's environment

<cow_2001>hmmm

<cow_2001>where is its environment variables?

<cow_2001>are

<cow_2001>maybe in the guix-daemon.service systemd file?

<cow_2001>ExecStart="GUIX_LOCPATH=... /gnu/store/...-guix-.../bin/guix-daemon --build-users-group=guixbuild" ?

<ajgrf>does anyone know the guile function i would use to transform the version "2.3.4" into "2_3_4"?

<bavier>(string-join (string-split "2.3.4" #\\.) "_")

<bavier>ajgrf: boost would be an example

<bavier>the "boost" package that is

<ajgrf>thanks!

<rekado>trying to update the bioconductor packages in place I get this error:

<lfam>Grr, most of my outbound emails from the past two days were not actually sent. Apologies if a conversation with me seemed to die unexpectedly...

<sneek>lfam, you have 1 message.

<sneek>lfam, civodul says: merging master into core-updates is OK :-)

<sandro_>hi :)

<lfam>Hello sandro_!

<sandro_>hello lfam

<sandro_>i'm just installed guix using the usb stick :)

<lfam>Oh, good! Everything works?

<sandro_>uhm Gnome doesn't work very well; but i must install more software.

<sandro_>how can i do to install new softwares ? (excuse me but i'm very noob about guix)

<lfam>Yes, GNOME is a work in progress. Can you be more specific about what's not working?

<sandro_>lfam: now i'm not in guix but with funtoo; but with guix i've some "random crash"

<lfam>Usually crashes aren't random ;)

<sandro_>now i'd like to install hexchat in guix rebooting the system.

<sandro_>how can i do to install software ?

<sandro_>i've installed it 10 minutes ago :D

<lfam>To install new software just for your current user, you'll want to use `guix package --install hexchat`. If you want to make hexchat available to all users, then you should add it to (packages) in your operating system configuration.

<sandro_>i must learn more & more about guix ... excuse me if 'm noob :(

<lfam>I recommend reading section 3 of the manual, Package Management: https://www.gnu.org/software/guix/manual/guix.html#Package-Management

<lfam>And also doing `guix package --help`

<sandro_>perfect... i go to eat something; then i will reboot in guix using hexchat so i can be more precise about bug reports :)

<lfam>Yes, precise bug reports are welcome :)

<sandro_>:) ..... 45 minutes ... cause i go to eat (20:26 in Saronnno , near Milan , IT) :)

<sandro_>write you later :)

<lfam>I wish I was near Milan, IT :)

<lfam>Although it's good where I am, too

<sandro_>lfam: where are You from ?

<lfam>sandro_: Northeast USA

<sandro_>Ah ok

<sandro_>what timew is in your country ?

<lfam>15 hrs

<sandro_>time*

<sandro_>ugh :D

<sandro_>here 21:07

<sandro_>now i reboot in guix to learn more about :)

<lfam>Oh, it's 15:02 here. Where did those 5 minutes come from? ;)

<sandro_>lfam: now 21:06:45

<sandro_>boh ... :|

<sandro_>Ok .. now i'm with my new guix using xfce and hexchat installed at "user level":)

<lfam>sandro_: Hooray!

<sandro_>thanx lfam :)

<sandro_>i've downloaded the pdf about the instructions for guix ... i must learn :)

<adfeno>sandro_: Your name raminds me of Brazilians named Sandro" .:D

<sandro_>Sandro is "contraction" of Alessandro , Alexander :)

<sandro_>I'm reading the handbook in PDF; and now i know how to install packages at "user level"; but to make possible 1 installation for all users, how must be the procedure ?

<lfam>sandro_: In the file you use to configure the system (often called "config.scm"), you must add the package to the (package) field, and add the package's module to the (use-package-modules) field.

<mark_weaver>sandro_: to add system-wide packages, add them to the 'packages' field of your OS configuration and rerun "guix system reconfigure"

<lfam>And then do the reconfigure, as mark_weaver said :)

<sandro_>uhm ... i've not understood; there is an example "step-by-step" ?

<lfam>sandro_: I don't think there is a "step-by-step" guide anywhere. I recommend you read 7.2.1 Using the Configuration System: https://www.gnu.org/software/guix/manual/guix.html#Using-the-Configuration-System

<lfam>Look for the fields we mentioned in the examples there. If you are still unsure, please ask again

<sandro_>but i must reconfigure the config.scm or which file ?

<lfam>sandro: Once you have made the changes in config.scm, do something like this: `guix system reconfigure /path/to/config.scm`

<lfam>I also recommend you do `guix system --help`

<lfam>You must do that as root

<lfam>That is, you must reconfigure as root. You can read the help without root.

<sandro_>for example, is correct the syntax (to have gloabal hexchat and evince ?

<sandro_>;; This is where we specify system-wide packages.

<sandro_> (packages (cons* nss-certs hexchat evince ;for HTTPS access

<sandro_> %base-packages))

<lfam>sandro_: Yes, that's right. But, you also need to add the package modules that contain hexchat and evince to the (use-package-modules) field. You can find out what module a package is in by doing `guix package --show=hexchat`

<lfam>Look for the "location"

<lfam>Hexchat is in gnu/packages/messaging.scm, so in (use-package-modules), you will do something like this: (use-package-modules messaging)

<lfam>To also add evince, it will be like this: (use-package-modules gnome messaging)

<random-nick>are runlevels planned for shepherd?

<lfam>Since evince is in gnu/packages/gnome.scm

<sandro_>ugh ....

<lfam>What?

<sandro_>i've not used shepherd

<sandro_>i'm a bit confused

<sandro_>root@ci74771ht ~# guix system reconfigure /etc/config.scm

<sandro_>guix system: error: failed to load '/etc/config.scm':

<lfam>Does that file exist?

<lfam>random-nick: I'm not sure. I haven't heard of anybody working on it recently.

<sandro_>what site you like to paste my config.scm ?

<lfam>paste.lisp.org

<sandro_>ok ... just a moment and thank You very much Master :)

<lfam>Heh, I am quite far from a master. I just happen to have a little more experience with Guix than you :)

<sandro_> http://paste.lisp.org/+6RE2

<lfam>See this line near the top? (use-package-modules certs)

<lfam>You need to add the modules that contain hexchat and evince to that

<lfam>`guix package --show=hexchat` will tell you what module hexchat is in (messaging)

<lfam>Also, I believe there is a typo here: (title 'de4vice)

<sandro_>but All in /etc/config.scm ?

<lfam>Yes, all in the same file

<sandro_>Thanx ... and these operations are similar to "declaring the use flags" in *too systems ?

<lfam>I'm not familiar with Gentoo, so I don't know

<sandro_>Ah ... ok .... excuse me and thanx :)

<lfam>In Guix (and GuixSD), packages are generally installed by a user, and only available to that user. When you add packages to config.scm, then those packages are available to all the users.

<lfam>That's what you are doing now. I don't know how that relates to Gentoo's use flags

<sandro_>fantastic :P :P :P

<sandro_>very intelligent tecnique :) very very good :)

<sandro_>it is difficult, but really "unique" :)

<lfam>I hope it's not too difficult once :)

<lfam>*once you learn it

<lfam>Are you familiar to with Debian / Ubuntu package management?

<sandro_>eh ... i'm not expert; but i love this world :)

<lfam>I ask because I want to make sure you understand the "per-user" thing, because it's very different from Debian (apt-get), Red Hat (yum), etc.

<lfam>With apt-get, you use `apt-get update` to update your list of packages. In Guix, you use `guix pull`. But, since Guix is per-user, `guix pull` is also per-user. So, when you do `guix pull`, you will probably want to do it once for root, and again for your user.

<lfam>Does that make sense?

<lfam> https://www.gnu.org/software/guix/manual/guix.html#Invoking-guix-pull

<sandro_>uhm i've troubles ....

<lfam>What happened?

<lfam>sandro_ ^

<sandro_>i've installed as root htop; but it doesn't run with my user ... now i paste my new /etc/config.scm ....

<sandro_> http://paste.lisp.org/+6RE4

<sandro_>ok

<lfam>htop is in the 'admin' module, but you didn't add 'admin'

<lfam> to (use-package-modules)

<sandro_>what can i do ?

<lfam>Add 'admin' to (use-packages-modules)

<lfam>I mean, (use-package-modules). There was a typo in my last message

<lfam>But, does it really work with (title 'de4vice)? That's a typo

<sandro_>yes

<lfam>Shouldn't it be 'device?

<lfam>Huh

<lfam>Interesting

<sandro_>cause i don't use disk-label but the "absolute path for the device

<alezost>ACTION thinks sandro_ didn't run "guix system reconfigure"

<sandro_>guix system reconfigure /etc/config.scm

<sandro_>guix system: error: failed to load '/etc/config.scm':

<sandro_>ice-9/boot-9.scm:2867:6: In procedure resolve-interface:

<sandro_>ice-9/boot-9.scm:2867:6: no code for module (gnu packages dbus)

<sandro_>it give to me error :(

<lfam>sandro_: Why did you put dbus in (use-package-modules)?

<lfam>You shouldn't need to do that for the packages you have in (packages)

<lfam>I have the same question about several of those modules you listed

<sandro_>guix package --show=htop

<sandro_>no .. htop wants ncurses

<alezost>sandro_: you just need: (use-package-modules certs messaging gnome admin)

<lfam>Also xfce, right?

<lfam>Oh, no, I'm wrong about that

<sandro_>about xfce i've do nothing; the system is reconfiguring itself :P

<sandro_>ok .... Great lfam: now htop starts for root & users

<lfam>Good :)

<sandro_>but i'm confused... this new system is difficult... i must to learn it :P

<lfam>I too found it difficult, at first, But soon I found it easy. Everything is difficult at the beginning :)

<sandro_>hehehe it's true :)

<sandro_>and ... to compile a software from sources .....?

<ng0>once you touched GuixSD you complaint about $other-system not having guix things

<lfam>ng0 is right!

<ng0>ACTION currently back on Gentoo and missing some GuixSD features

<lfam>At least I hope you have Guix on Gentoo ;)

<ng0>not yet

<sandro_>I've Funtoo & guix now :)

<sandro_>But *too is very simple with portage

<sandro_>portage is a "formidable" package-manager for me

<ng0>i'll just move guixsd into a vm on it once I have time, but i have an work in progress (read: works but needs debugging) ebuild for guix on gentoo

<sandro_>ng0 ugh ... You're "a monster" :o

<sandro_>(in good sense)

<lfam>sandro_: About building from source, you should read 3.3 Substitutes and 6.1 Invoking guix build

<sandro_>i chatted with Daniel Robbins .... for me a very great man :)

<sandro_>ok lfam .....

<ng0>afaik it's either in the "official" location of ybti-overlay or my working (syncing between both) overlay

<lfam>In Guix, the difference between building from source and downloading binaries is "transparent".

<sandro_>You're very very very kind ... thanx for your suggestions.

<lfam>If there are binary "substitutes" available, and you've chosen to use substitutes (default in GuixSD), then you will download the substitutes. Otherwise, you'll build from source.

<sandro_>but i must "enter" in the guix "philosophy" :)

<lfam>Yes :) The manual will help

<lfam>Also, `guix --help`

<sandro_>now i want to try another installation for the "global system";

<lfam>And from there, `guix $command --help`

<sandro_>thunderbird is in the repository ?

<ng0>that's http://c.n0.is or git://cheettyiapsyciew.onion/youbroketheinternet-overlay , for the guix / guix-bin ebuilds. but it's currentlybehaving weird and you need a guile from this exact overlay or your gentoo system will be sad (before we had this it broke the complete system for me once)

<lfam>sandro_: Check for yourself, with `guix package --search thunderbird`

<ng0>thunderbird is not available on guix.

<ng0>last time i checked at least

<lfam>Or, --search=thunderbird

<lfam>Try reading the help text, and the manual. I promise you will learn more quickly :)

<sandro_>lfan: thunderbird: unknown package

<lfam>Sounds like we don't have thunderbird, yet

<sandro_>and evolution ?

<ng0>claws should be there

<ng0>ACTION has too much space occupied by unnecessary info like this

<sandro_>mumble mumble: now it seems that guix is recompiling the system :o

<sandro_>but ... in this case, how to add the flags "-march=native -O3 -ftree-vectorize" ?

<sandro_>globally

<lfam>Guix doesn't have a user-facing method to set compiler flags globally

<sandro_>ah ... ok ....

<sandro_>thx lfam for all your aids :)

<lfam>I'm not familiar with the part of Guix that calls GCC. It's possible that we already set some of those flags. I'm not sure

<sandro_>but it is better to learn "step by step" about guix :)

<lfam>That's how I learned :)

<sandro_>the mine was only just a curiosity :)

<ng0>there might/could be a place where guix has set this, like other systems make.conf .. but i don't know it for guix

<lfam>Slightly relevant discussion: http://lists.gnu.org/archive/html/guix-devel/2015-12/msg00702.html

<lfam>Also: http://lists.gnu.org/archive/html/guix-devel/2015-10/msg00902.html

<lfam>AFAICT, that work has not been merged yet

<ng0>app-portage/pfl is a nice toolset. includes e-file, which can locate which package provides which file. it's not that it's necessary due to the nature of guix, but something similar could be useful.

<sandro_>ng0: i've made a little test; in some case the -march=native can emprove performances :) http://forum.fedoraonline.it/viewtopic.php?id=24325

<ng0>i only use --march=native.

<sandro_>ng0 ... and how can i do to add that flag in guix ?

<ng0>see above, idk

<sandro_>boh ...

<sandro_>there is a guix forum and a guix bug-report site ?

<alezost>sandro_: our guix forums are: guix-devel@gnu.org and help-guix@gnu.org; for bug reports: bug-guix@gnu.org

<sandro_>ok thanx. however, in Gnome 3.X when i try to add a program to the "left bar for preferred apllication" , Gnome return to a "primitive state" ...

<sandro_>so i, for now i'll use xfce

<sandro_>but i will take a look about Gnome everyday.
