Qownnotes: Build fails on Slackware 14.1 64 bits [SOLVED]

[richarson]

I'm obvoiusly missing something but I'm not sure what.
Do I need some -D flag to specify QQmlEngine's location?

I tried googling but found nothing concrete, any hints appreciated.

[pbek]

That's strange, just using qmake; make should be enough...

Maybe you need to set a QTDIR (and maybe also PATH), like here:
https://github.com/pbek/QOwnNotes/blob/develop/.travis.yml

[pbek]

Usually QML is located inside a package like libqt5-qtdeclarative-devel (example from openSUSE).

[richarson]

Slackware doesn't usually split packages up so there's only qt5 with everything, my env has:

$ env | grep QT
QT5DIR=/usr/lib64/qt5
QT4DIR=/usr/lib64/qt
QT_PLUGIN_PATH=/home/richis/.kde/lib64/kde4/plugins/:/usr/lib64/kde4/plugins/

and $QT5DIR is already in my $PATH but after $QT4DIR

I'll try setting QTDIR=$QT5DIR and removing $QT4DIR from my $PATH.

Thanks for the pointers!

[richarson]

Man, I'm so stupid!

I have both qt4 and qt5, so I have qmake and qmake-qt5 ...

It's compiling now, thanks for your help and sorry for the false alarm.

This is the series of commands I had to use, if you want to add instructions for Slackware (but if I like QOwnNotes, I'll probably make a slackBuild script and contribute it to https://slackbuilds.org/):

# After installing qt5 from AlienBOB's repositories
# http://bear.alienbase.nl/mirrors/people/alien/sbrepos/14.1/x86/qt5/
# or
# http://bear.alienbase.nl/mirrors/people/alien/sbrepos/14.1/x86_64/qt5/

git clone https://github.com/pbek/QOwnNotes.git -b master
cd QOwnNotes/
git submodule update --init
cd src/
qmake-qt5
make
sudo make install

[pbek]

I'm glad it worked now! But to be true I don't know if make install does all the things to do...
You can see here what I did for OBS:
https://github.com/pbek/QOwnNotes/blob/develop/obs/qownnotes.spec

Slackbuilds: That's great! If it's something I should maintain (e.g. update commit tags) I happily will...
Also there are source code archives (with the git submodules included) here: https://sourceforge.net/projects/qownnotes/files/src/

[richarson]

OK, I checked the .spec and replicated those install commands in my script, seems to be fine now!

The slackbuild is in my git repo for the moment, if you want to check it out:
https://github.com/richarson/slackbuilds/tree/master/14.1/qownnotes

I've no problem maintaining it but if you want to take it that's fine also.

Slackbuilds.org is not accepting new submissions ATM (testing and waiting for Slackware 14.2, which is coming Real Soon Now!) but I can check their mailing list, or just wait till 14.2 gets released.

[richarson]

Well, it compiles and installs fine, but segfaults :(

A gdb backtrace shows it seems to be trying to use some KDE files (/usr/lib64/libkdecore.so.5, /usr/lib64/libproxy/0.4.11/modules/config_kde4.so).

I'm using KDE SC 4.14.6 BTW, no Plasma 5 for Slackware 14.1, can that be a problem?

[pbek]

SlackBuild: wonderful, great work! I guess I will create a repository and update it as part of my build process, so you don't have to worry! Thanks a lot for your help!

Segfault: Maybe you have to set QTDIR because you use a different version of Qt.
We do that at http://www.qownnotes.org/installation#Linux for Ubuntu Trusty...
/opt/qt56/bin/qt56-env.sh does the magic in that case...

If you can't find the variables (I didn't find the content of the shell script) I will take a look if I can find it somewhere...

Maybe this helps:

export QTDIR="/opt/qt55" && export PATH="$QTDIR/bin:$PATH" && qt55-env.sh
export PKG_CONFIG_PATH="/opt/qt55/lib/pkgconfig:$PKG_CONFIG_PATH"

Can we integrate a start script with the variables into the SlackBuild?

[pbek]

SlackBuild: Is there a "best practice" to use such a git repository on Slackware? I haven't found anything else rather than cloning the repository, downloading the archive manually, installing all dependencies manually and running the SlackBuild script...
And so far I didn't manage to install Qt5...
Do you have any insights on this, @richarson?

[richarson]

Sorry for my late reply (stuck at work).

You're basically right, to use the slackbuild script, download the content of https://github.com/richarson/slackbuilds/tree/master/14.1/qownnotes, install the dependencies listed in the .info file, e.g.:

wget http://bear.alienbase.nl/mirrors/people/alien/sbrepos/14.1/x86_64/qt5/qt5-5.5.1-x86_64-4alien.txz
sudo installpkg qt5-5.5.1-x86_64-4alien.txz

Then donwload http://downloads.sourceforge.net/project/qownnotes/src/qownnotes-16.06.10.tar.xz in the same directory as the slackbuild and execute ./qownnotes.SlackBuild as root.

That'll leave a package in /tmp that you can install with:

sudo installpkg /tmp/qownnotes-16.06.10-x86_64-1_SBo.tgz

I'll check your recomendations later at home, thanks!

[pbek]

Thank you for your explanation, I will try that.
Is that the usual way to do things? I saw you added a lot of meta information, like the qt5 dependency and the download link with checksum to your repository. What is the use of the repository?

I want to write an install guide for Slackware for https://github.com/pbek/qownnotes-slackbuilds.

[pbek]

I installed Qt5 and tried to build QOwnNotes, but I have a missing libicui18n, did you have the same problem? Do you know where to get it for Slackware?

Edit: I'm running a Slackware 14.2.

[pbek]

That was my problem. I only found a ready Slackware 14.2 Virtualbox VM, no 14.1. (I have no experience setting up Slackware myself). libicui18n.51 is for 14.1, 14.2 is using libicui18n.56... You you know a VM with e.g. KDE for 14.1 or a Qt 5 package for 14.2?

[richarson]

Re slackbuilds: yes, usually you manually download and install slackbuilds and its dependencies, but there are some automation tools (sbotools, slpkg, etc).

Re versions: I guess with Slackware 14.2 being so close there's no point in triyng to make it work on 14.1. If you already have a VM with -current (a.k.a. 14.2 development) you can install a (newer) qt5 compiled for -current from here:

http://bear.alienbase.nl/mirrors/people/alien/sbrepos/current/x86_64/qt5/

[pbek]

Sounds promising, I will test that. Thanks a lot!
Did you have any luck yet with running QOwnNotes with Qt 5?

Haven't tried yet, hopefully tonight I will.

The "official" QOwnNotes repository with the current version 16.06.12 is now in place: https://github.com/pbek/qownnotes-slackbuilds

[pbek]

I still get errors when building for Slackware 14.2, maybe this will work when Slackware 14.2 is released...

I wrote a disclaimer for http://www.qownnotes.org/installation#Slackware.
If you get the chance to test the build process that would be awesome.

[richarson]

Variables: qt5 package comes with a file that sets some env:

cat /etc/profile.d/qt5.sh
#!/bin/sh
# Environment variables for the Qt package.
#
# It's best to use the generic directory to avoid
# compiling in a version-containing path:
if [ -d /usr/lib64/qt5 ]; then
  QT5DIR=/usr/lib64/qt5
else
  # Find the newest Qt directory and set $QT5DIR to that:
  for qtd in /usr/lib64/qt5-* ; do
    if [ -d $qtd ]; then
      QT5DIR=$qtd
    fi
  done
fi
PATH="$PATH:$QT5DIR/bin"
export QT5DIR

PKGCONFIG and PATH shouldn't be a problem, I'll try setting QTDIR=$QT5DIR

Is there a way to build with debug on (besides not stripping the binaries)?

[pbek]

Did you execute /etc/profile.d/qt5.sh and it still didn't work?

debug: You just have to use the parameter CONFIG+=debug with qmake.

[richarson]

Yes, QTDIR gets picked up fine but no luck on Slackware 14.1 so far, still segfaults.

Right now I'm upgrading 2 VMs (32 and 64 bits) from Slack 14.1 to current and will try there.
In the meantime I'm triyng to do a debug build on my laptop.

Oh, and realized that if I delete ~/.config/PBE QOwnNotes wizards starts fine but segfaults later.

[richarson]

Weird thing, I just started QOwnNotes and the wizard started so I clicked next.

If I click on "open ownClod settings" it segfaults.
If I click Next and "open network settings" I can configure it, change "Use system proxy" to "No Proxy" and QOwnNotes doesn't segfault, yay!

I'm collecting QOwnNote's debug information from before and after running the wizard, would you like me to send them to you or simply setting a default "networking/proxyType" is enough?

[pbek]

I'm curious what segfaults... I remember having compile problem with the Qt library under 14.2. If you send me the errors I will take a look at them... I wonder if the Qt 5 libraries for Slackware have some problems...

[richarson]

Attached a .zip with QOwnNotes Debug Information1.md (first run, before configuring the proxy) and QOwnNotes Debug Information2.md (succesful run, after configuring the proxy).

OK, my Slack 14.2 32 bits VM finished the upgrade to current.

I installed qt5 and libxkbcommon (a dependency for qt5):

wget http://bear.alienbase.nl/mirrors/people/alien/sbrepos/current/x86/qt5/qt5-5.6.1_1-i486-1alien.txz
wget http://bear.alienbase.nl/mirrors/people/alien/sbrepos/current/x86/libxkbcommon/libxkbcommon-0.5.0-i486-1alien.txz
installpkg libxkbcommon-0.5.0-i486-1alien.txz qt5-5.6.1_1-i486-1alien.txz

installpkg /tmp/qownnotes-16.06.12-i486-1_SBo.tgz

After that, I successfully compiled QOwnNotes and it seems to work fine :)

I tried with a fresh user and didn't get the segfault, so I guess the problem lies somewhere in either Slack 14.1 or qt-5.5.1.

[richarson]

BTW, I didn't need to install libproxy, your VM is probably "incomplete", as Slackware is intended to be installed full.

You might want to try slackpkg install-new to install missing packages.

[richarson]

Another success on 14.2 64 bits! \o/

installpkg /tmp/qownnotes-16.06.12-x86_64-1_SBo.tgz

segfault: it really seems to be a kde4 thing...

#0  0x00007fffd73981ba in ?? () from /usr/lib64/libkdecore.so.5

#2  0x00007fffd77c89b0 in ?? () from /usr/lib64/libproxy/0.4.11/modules/config_kde4.so

it looks like a kde4 library was loaded...

Slack 14.2: Thanks a lot for the libxkbcommon hint, I will try that! did you have to set some additional environment variables?

QSqlQuery: I will see what causes this errors...

[pbek]

I still seem to miss libmozjs, do you have any idea where I can get one for 14.2? I already tried a slackpkg install-new.

[pbek]

I fixed some database not open errors and possible problems with the database in the current version 16.06.13.

[richarson]

Slack 14.2: no additional variables, stock install worked fine!

libmozjs185.so.1.0 comes from js185.

In case you get another missing library you can search for it with slackpkg:

# slackpkg file-search libmozjs185.so.1.0

Looking for libmozjs185.so.1.0 in package list. Please wait... DONE

The list below shows the packages that contains "libmozjs185\.so\.1\.0" file.

[ installed ] - js185-1.0.0-x86_64-1

You can search specific packages using "slackpkg search package".

[pbek]

slackpkg file-search libmozjs185.so.1.0: that's a great advice, thank you!
I could build QOwnNotes, but when I start it I get a seg fault as well. :)

I tried to set a QTDIR manually, but that neither helped. I guess that's a thing of the Slackware system I'm running. I'll trust your installation and updated http://www.qownnotes.org/installation#Slackware. :)

[richarson]

From what I read (nothing official, though) $QTDIR is deprecated in favor of $QT4DIR and $QT5DIR, (probably so Qt-4.x and Qt-5.x can coexist in the system) so the variable shouldn't be a problem.

The segfault you get is weird, but since it works on a full Slackware-current (which is the recommended and supported way for slackbuilds.org) we're probably safe.
Maybe add a warning that if you get segfaults try setting "No Proxy" in the wizard?

We'll see when 14.2 comes out :)

Out of curiosity, where did you get your slackware VM?

[pbek]

I also tried to set $QT5DIR...
VM: I didn't find any, I only found a 14.2 live cd: https://sourceforge.net/projects/slackex/

[richarson]

Yeah, but QT5DIR an related are set from /etc/profile.d/qt5.sh

VM: Ah, maybe slackex people do something different, as it's not a vanilla slackware.

If you want to try installing from scratch, AlienBOB maintains an unofficial (but still vanilla) slackware-current ISO at:
http://bear.alienbase.nl/mirrors/slackware/slackware64-current-iso/slackware64-current-install-dvd.iso

[pbek]

QT5DIR: maybe I should try and run that script (I didn't logout)
AlienBOB: Would I need to install kde for myself?

[richarson]

QT5DIR: It still should be picked up by the slackbuild, as it runs in a subshell and should parse the script in profile.d, otherwise I don't think qownnotes would have even compiled :)

AlienBOB: if you do a full install you get kde (4) too, by default the only unselected packages are internalization related. And if you want a graphical login I think after install you have to edit /etc/inittab and change id:3:initdefault: with id:4:initdefault:

[pbek]

Thank you for your advices!

[pbek]

@richarson, We are now using make install in the SlackBuild file, could you please test if the installation still works?
https://github.com/pbek/qownnotes-slackbuilds/blob/master/14.2/qownnotes/qownnotes.SlackBuild

[richarson]

Almost:

install -m 755 -p /tmp/SBo/qownnotes-16.07.2/QOwnNotes /tmp/SBo/package-qownnotes/usr/bin/
install: no se puede efectuar `stat' sobre «/tmp/SBo/qownnotes-16.07.2/QOwnNotes»: No existe el fichero o el directorio

And the relevant lines from previous version, notice the build/ in the first line, I made the same mistake in my first slackbuilds :) :

install -D -m 0644 QOwnNotes.desktop $PKG/usr/share/applications/QOwnNotes.desktop

[pbek]

Thank you for testing!
Do you have any idea what we need to change that the slackbuild will work?

[richarson]

Maybe adding:
install -D -m 0755 build/QOwnNotes $PKG/usr/bin/QOwnNotes

But I think that should be fixed in the building system?

Or ditch the:

mkdir -p build
cd build
  qmake-qt5 ..

And simply do:

I don't know how it's done on other platforms.

[pbek]

I now did the latter, does it work better now?

[richarson]

Works like a charm :)

BTW, I loaded 16.07.1 before upgrading to this version and it prompted me for an upgrade.
Wasn't that supposed to be avoided by using "define RELEASE" in release.h? Or did I missunderstood its meaning?

[pbek]

works: great! thank you very much!
update: It should set a default setting if there were no other previous setting. Can you please tell me what you have set in the general settings at Update dialog?

[richarson]

It's unchecked, but since I do an initial config to avoid the segfault maybe that's the problem.

I should check on Slackware 14.2 which doesn't have the segfault and see what happens there.

[pbek]

Just check it and everything is fine. :)

[richarson]

Last weekend I upgraded my laptop to Slackware 14.2, I just compiled qownnotes-16.07.3, deleted ~/.config/PBE/ and ran it, it's working correctly!

Are you planning on submitting your slackbuild to slackbuild.org?
If yes, I think the safest bet is to submit only for 14.2 but first remove libproxy from REQUIRES in qownnotes.info since it's in Slackware base, and leave out dobuild.sh from the submission (you can keep it in you repo, of course).
If not, then you should change the SBo tag to, say, pbek so people don't mistake your slackbuild/package for an SBo one.

[richarson]

Here are the submission guidelines if you'd like to read them:
https://slackbuilds.org/guidelines/

[pbek]

working correctly

great to hear, thank you!

slackbuilds

Seems like I would have to wait a bit: https://www.slackbuilds.org/submit/

Will I be able to git-push to a git repository or how does that work?

[richarson]

Weird, I thought it was already open for bussiness :)

There is a git repository (https://slackbuilds.org/cgit/, git://slackbuilds.org/slackbuilds) with a branch per version but I'm not sure if/how they accept submissions there.

You can also send a tar.gz via their mailing list: https://lists.slackbuilds.org/mailman/listinfo/slackbuilds-users.

I'm subscribed to the mailing list if you want me to ask'em something.

[pbek]

I need a process that is scriptable, otherwise I would go mad when doing releases. ;)
Currently I use this script for Slackware:
https://github.com/pbek/QOwnNotes/blob/develop/build-systems/slackware/build-for-slackware.sh

It uses this SlackBuild und replaces the version number:
https://github.com/pbek/QOwnNotes/blob/develop/build-systems/slackware/qownnotes.SlackBuild

[richarson]

I'll ask how to submit via git if that works for you, maybe they can pull from your repo directly and exclude the dobuild.sh.

As a last resort, you could automate making a tar.gz and sending it by mail from build-for-slackware.sh, I can give it a try.

[pbek]

Any help is appreciated. ^_^

We can also remove the dobuild.sh if it isn't needed any more, I just added it because I thought it was convenient...
