parzzixHello?02:01
parzzixI'm looking to get involved....need guidance and place to start..off to bed, but if you see this shoot me an email at tim at apples dot email..thanks02:58
valorieparzzix: please join the Kubuntu-devel list and tell us all what you are interested in doing04:00
valorieand we'll do our best to point you in the right direction04:00
valorieor just talk to me now04:00
fewcha_How to install Qt 5.4 in Kubuntu?05:06
fewcha_I was trying to build plasma from source from https://community.kde.org/Plasma/Building but when I am running kdesrc-build, it is giving the following error when it is trying to build kxmlrpcclient (build system KDE) from frameworks: https://paste.kde.org/p40jti5si/eumyas05:19
fewcha_I wanted to contribute to the kde plasma-mediacenter, but since it is not possible to build the plasma-mediacenter separately from source because it has runtime deps to plasma-workspace, so I need to build plasma-workspace before that05:20
fewcha_and for that I need Qt 5.4 in my system05:20
fewcha_so can someone please tell me how to install Qt 5.4 in Kubuntu 14.04.2 LTS ?05:21
fewcha_Only qt4-x11 is there in the Kubuntu backports as shown in https://launchpad.net/~kubuntu-ppa/+archive/ubuntu/backports/+index?batch=75&direction=backwards&memo=825&start=75005:23
fewcha_although libqt5core5a is already installed and the newest version05:25
fewcha_and dpkg -l|grep -e libqt |grep -e dev is giving output https://paste.kde.org/p0d5khqkn/dhp7i1 so I am not sure what I am missing05:27
valoriehi fewcha_ -- I would ask in #kde-devel06:24
valoriemost of our devels are gone this particular weekend06:24
valorieyou probably will get most of the dependencies you need with something like sudo apt install build-dep plasma-workspace plasma-mediacenter06:25
valorieor so06:25
fewcha_valorie: okay06:29
fewcha_thanks06:29
fewcha_:)06:29
valoriegood luck06:30
fewcha_:)06:31
fewcha_valorie: well, here's what I am getting anyway: https://paste.kde.org/pewfexu6t/gy6q7f07:11
valorieoops, leave out `install`07:18
valoriemy mistake07:18
fewcha_ah, okay :)07:18
valoriebuild-dep is a command, not a packaGE07:18
valorieand you may have to do that twice07:18
valorieonce for plasma-workspace and once for plasma-mediacenter07:19
valoriebut try it for both to save time07:19
fewcha_okay07:19
fewcha_valorie: "sudo apt build-dep anything" is showing "E: Invalid operation build-dep"07:21
valoriethat's strange07:22
valorieworks for me07:22
valorieI'm building amarok right now07:22
* fewcha_ is going through https://bugs.launchpad.net/ubuntu/+source/apt/+bug/131029407:22
ubottuUbuntu bug 1310294 in apt (Ubuntu) "apt is missing build-dep changelog and source commands." [Low,New]07:22
valorieI just ran `sudo apt-get build-dep amarok`07:22
valorieewww07:23
fewcha_oh its apt-get07:23
fewcha_sorry07:23
valorieah, apt is behind apt-get for that I guess07:23
valorieI usually use apt, and if that doesn't work, fall back to the oldie but goody apt-get07:23
fewcha_okies :)07:24
fewcha_hmm, i think it worked07:25
fewcha_but that's not what I require to fix the problem imo07:29
fewcha_let me just see what the kde-devel guys have to say about this :)07:30
valorieget more dependencies installed is never a bad thing07:30
fewcha_hmm, right :)07:32
fewcha_actually I tried a "sudo apt-get build-dep kxmlrpcclient" as well07:33
fewcha_but it's unable to find a source package for that07:33
valorie!info kxmlrpcclient07:35
ubottuPackage kxmlrpcclient does not exist in wily07:35
valorie!info kxmlrpc07:36
ubottuPackage kxmlrpc does not exist in wily07:36
fewcha_btw, kxmlrpcclient because https://paste.kde.org/pokb6fxjb/ekwe5n07:37
valorie$ apt-cache search kxmlrpc07:37
valorielibkblog4 - client-side support library for web application remote blogging APIs07:37
valorielibkf5xmlrpcclient-data - data files for kxmlrpcclient07:37
valorielibkf5xmlrpcclient-dbg - debug symbols for kxmlrpcclient07:37
valorielibkf5xmlrpcclient-dev - development files for kxmlrpcclient07:37
valorielibkxmlrpcclient4 - simple XML-RPC client library07:37
valorieyou probably need the -dev07:37
fewcha_oh07:38
valorieapt-cache search helps07:38
valorieif at first it finds nothing, take off some characters07:38
fewcha_its showing me libkblog4 and libkxmlrpcclient407:38
valorienotice what I searched for07:39
fewcha_yeah I have done that only07:39
fewcha_rpc07:39
valorieapt-cache policy packagename shows you what you have installed07:39
valorieI think apt show does about the saem07:40
valoriesame07:40
fewcha_okay07:40
fewcha_so I am installing libkf5xmlrpcclient-data, libkf5xmlrpcclient-dbg, and libkf5xmlrpcclient-dev then07:41
valorieand you can use ^ as a wildcard sometimes07:41
valorieif you just do -dev, it will pull in what you need07:41
valoriesimpler07:41
valorieI've never done kdesrc-build so I'm not able to make sense of your whole paste07:42
fewcha_hmm07:43
valoriebut trying to build amarok, I'm coming up with the same "Unable to compile a basic Qt application.  Qt has not been found correctly."07:43
valorieso I'm thinking there is a common problem here07:44
fewcha_hmm, so how did you fix it when you got that the first time?07:44
fewcha_is there any way to build plasma-mediacenter without using kdesrc-build?07:45
valorieI didn't07:45
valorieah, I don't think so07:45
valorieI read #kde-devel and #plasma07:45
valorieand that's how everyone does it07:45
valoriebut those are the folks you need to ask07:46
valoriebshah is very helpful if he's about07:46
fewcha_I cloned mediacenter separately locally and when I do "cmake -DKDE_INSTALL_USE_QT_SYS_PATHS=ON -DCMAKE_INSTALL_PREFIX=`kf5-config --prefix` .." from its build folder I get an error starting with "kf5-config: command not found"07:48
fewcha_yeah, I have talked to him recently in private07:48
valoriehe's in this chan as well so he must be not at his keyboard, or not looking at IRC07:49
fewcha_he said that I need to install Qt 5.4 in my system to run kdesrc-build correctly and told me to ask it in #kubuntu and they further asked me to ask in #kubuntu-devel07:49
valorieit's nearly 1 am here, so I'm going to write to amarok-devel list about my error and see if I get any insight there07:50
fewcha_he also told me to ask it in #kde-devel as well :)07:50
fewcha_okay, thanks a lot :)07:50
valorie!info qt07:50
ubottuPackage qt does not exist in wily07:50
valorieright, tell me the packagename silly ubottu07:51
fewcha_haha :D07:51
valoriehttps://wiki.qt.io/Install_Qt_5_on_Ubuntu07:52
fewcha_hmm, I have gone through that, but maybe it is for 5.0.207:53
valorieseems taht `sudo apt-get install build-essential libgl1-mesa-dev` might be useful07:54
* valorie tries07:54
valorieI already have it07:54
valoriegrrrr07:54
fewcha_so do I :D07:55
fewcha_btw, this: https://paste.kde.org/pcy2gdzia/qcqstr in case it helps07:57
valorieI hope never to mess with cmake past pasting in the correct command07:58
valorieof course apt search qt filled bash's buffer08:00
valoriethere has to be a meta-package08:00
valoriemaybe muon will tell me08:00
valorieaha, qtbase5-dev08:02
valorieversion 5.4.108:03
valorienot sure that's right, but you can ask08:03
valorieI doubt I need that for amarok08:04
fewcha_hmm, qtbase5-dev seems to be already installed here08:27
valorieok08:35
* valorie has got to head bedward08:35
valorieI hope you can get some help later08:36
fewcha_valorie: cool, btw please let me know when you get some reply from the amarok-devel list08:36
fewcha_thanks :)08:37
fewcha_nite08:37
fewcha_:)08:37
valorieah, I already found out that trying to build a Qt4 application with Qt5 won't work08:37
fewcha_okay08:38
valoriehas to be a separate install, separately pointed to08:38
* valorie has not enough time to set that up08:38
fewcha_cool08:38
fewcha_will talk later then :)08:38
santa_good morning09:54
santa_valorie: you don't need a separate installation to build qt programs, this is the script I'm using to call cmake for building krecipes: https://paste.kde.org/pwxgprmlv09:54
santa_export QT_SELECT=4 is the important bit09:55
murthy_need to paste image, which one should I use?10:20
santa_I guess can use this one: http://imagebin.ca/10:22
murthy_http://imagebin.ca/v/27Sckxd8zprg10:29
murthy_I am trying to troubleshoot my kubuntu 15.04. The problem is it takes 3 mins to shutdown. I found that kactivitymanager segfaults using dmesg and so I opened it in gdb to find the above error. Can kactivitymanager be disabled for testing purpose and is it safe?10:32
murthy_Further guidance to find the bug would be helpful 10:32
santa_murthy_: could you check if you have libqt5sql5-sqlite installed?10:33
murthy_santa_: ya, its installed, I check it now. I had seen the error message and found the line libqt5sql so so I found the containing package which you told me. I even reinstalled it yesterday, just in case it got corrupted. I checked all the packages with debsums10:36
murthy_santa_: Can I run a check on the sql database in my system10:37
murthy_santa_: Can a corrupt database cause lead kactivitymanager to segfault? I am not able to get a backtrace since the process crashes after the shutdown gets initiated. You could see that in the image10:39
murthy_santa_: Yesterday I pasted my kernel log here. If you want to take a look I will give you10:40
