How get new qtox for Debian ?

I will try to show how to easily compile from the source code and install qtox for Debian. This is a guide for more advanced users, because

this is not easy
always install checked packages from the Debian repository for security.

And here is problem, Debian not support Qtox.

How start ?

1. Download qtox source code.

https://github.com/qTox/qTox

on website find “releases” bookmark and click. And download the latest source code tar.gz . For me today, this is v1.13.0

2. Compile source code.

In theory

$ mkdir build
$ cd build
$ cmake ..
$ make

But not this time, I will do a little differently, I will install the package in the home directory.

First unpack qTox-1.13.0.tar.gz Go inside qTox-1.13.0 folder from terminal in folder qTox-1.13.0 ( watch tutorials if you don’t know how something )

copy each command separately, paste, edit and run.

mkdir -p /home/your_user_name/NIC/
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/home/your_user_name/NIC/ ..

First command will create folder NIC

… second will create “build” folder

… third will go to build folder

… Last command “cmake”will check installed dependencies ( header files, *.h ) needed to compile source code. If you see any error, read and install needed dependencies from Synaptic. In Debian most needed dependencies for compile with headers will have name “ *-dev “ ( on other than Debian may have “ *-devel “ ) Something else, I added also path where I want install ready package, then I may easily remove the package after “ make install “ command. And … this will ~/home directory, so I don’t need use root account to install files.

Warning !

Everything what you have in your home directory, it can be read or overwritten by a malicious program. So some applications you can run from sandbox or install and run from other user account with appropriate permissions.

INFO:

$HOME or " ~ "  --> this is path to your home directory
write in terminal  " mkdir --help " then 
"man mkdir" for more info about this command ( with " q " key, you can exit )
$  --> You see it from user account
#  --> You see this from root accout, 
don't use root, if you don't need for own security

This is example, when I wrote
"your_user_name"
you need change this to own user name from /home/ path.

Error with sqlcipher

Call Stack (most recent call first):
  cmake/Dependencies.cmake:105 (search_dependency)
  CMakeLists.txt:80 (include)

This is exmaple when you need install libsqlcipher-dev from Synaptic.

This time for me this is more important.

I don’t know what you did before, but I had ( long time ago ) problem run new Qtox, problem was with new libsqlcipher0 3.2.0-2

[22:13:38.547 UTC] core/core.cpp:270 : Debug: Loading user profile
[22:13:38.547 UTC] core/core.cpp:132 : Warning: Core starting with IPv6 disabled. LAN discovery may not work properly.
[22:13:38.627 UTC] persistence/db/rawdatabase.cpp:572 : Warning: Failed to prepare statement "SELECT count(*) FROM sqlite_master" with error 26
[22:13:38.627 UTC] persistence/db/rawdatabase.cpp:181 : Warning: Database is unusable, check that the password is correct
[22:13:38.628 UTC] persistence/db/rawdatabase.cpp:116 : Debug: Couldn't create the backup of the database, won't upgrade

so I installed previous version libsqlcipher0 3.2.0-1.1~bpo80+1 from jessie-backports repository and I pinned package. This is solution, when you want update system with out this package.

 Now I tested, Qtox-1.13.0 working with 
  libsqlcipher0  3.2.0-1.1~bpo80+1
  libsqlcipher0  3.4.1-1
but not with 
  libsqlcipher0  3.2.0-2

How install other version package ?

I use Debian 9.2 stretch

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 9.2 (stretch)
Release: 9.2
Codename: stretch

And first I need undo things which I did before. I pinned libsqlcipher0 3.2.0-1

$ cat /var/lib/synaptic/preferences
Package: libsqlcipher0
Pin: version 3.2.0-1.1~bpo80+1
Pin-Priority: 1001

I can remove file or “comment out” with “ # “ this lines inside file.

$ cat /var/lib/synaptic/preferences
#Package: libsqlcipher0
#Pin: version 3.2.0-1.1~bpo80+1
#Pin-Priority: 1001

After this in Synaptic I can install other libsqlcipher version. But this is not all. Next thing, what I need do, this is
in /etc/apt/sources.list comment with “#” all working repositories and uncomment ( remove “#” ) repository from where we want download libsqlcipher.

For example: repository which which I comment

# deb http://httpredir.debian.org/debian/ stretch main contrib non-free

( if you want use older package, you should “pin” before system update )

and repository which I added for libsqlcipher0 3.2.0-1.1~bpo80+1

deb http://ftp.debian.org/debian jessie-backports main

or for libsqlcipher0 3.4.1-1

deb http://ftp.pl.debian.org/debian/ buster non-free main contrib

then I can refresh Synaptic and download libsqlcipher-dev which I want.

Something else … only info …

I use this repository

deb http://deb.debian.org/debian/ stable main contrib non-free

instead

deb http://httpredir.debian.org/debian/ stretch main contrib non-free

because I wanted have “ Debian rolling release “ I’m not sure now, but new repository I get probably from https://debgen.simplylinux.ch/ … if you want also use.

When the cmake script finishes checking dependency successfully, the final part will look like this …

-- GTK found
-- FILTERAUDIO not found
-- not using filteraudio, libfilteraudio not found
-- CMAKE_C_FLAGS: 
-- CMAKE_CXX_FLAGS:  -std=c++11 -fno-exceptions -fno-rtti -Wstrict-overflow -Wstrict-aliasing -Werror -fstack-protector-all -Wstack-protector -pthread -pthread
-- Configuring done
-- Generating done
-- Build files have been written to: /home/tele/Pulpit/test/Qtox/qTox-1.13.0/build

After that, you can edit /etc/apt/sources.list again for activate stable repository, and disable others.

Then we will start compiling source code.

$ make

When the make finishes compiling source code successfully, the final part will look like this …

[ 99%] Built target test_posixsignalnotifier_automoc
Scanning dependencies of target test_posixsignalnotifier
[ 99%] Building CXX object CMakeFiles/test_posixsignalnotifier.dir/test/platform/posixsignalnotifier_test.cpp.o
[100%] Building CXX object CMakeFiles/test_posixsignalnotifier.dir/test_posixsignalnotifier_automoc.cpp.o
[100%] Linking CXX executable test_posixsignalnotifier
[100%] Built target test_posixsignalnotifier

3. Install source code.

You can do it in two ways

install with “ make install “ command,

minuses this solution …

you will have to manually delete files only. pros this solution…
if you will install to one folder, it’s not hard remove files
if you will install somewhere to ~/home , you don’t need use root account.
or build .deb package, then after install you can remove from Synaptic.

Because I don’t know how build professional .deb package, and I do not have enough time, So I used simple, not professional, tool for this ( checkinstall ). ( if you don’t have checkinstall, you can install )

Run command from terminal …

$ checkinstall --install=no

After that command I choose

The package documentation directory ./doc-pak does not exist. 
Should I create a default set of package docs?  [y]: n

And I changed …

This package will be built according to these values: 

-  Maintainer: [ tele ]
-  Summary: [ A New Kind of Instant Messaging ]
-  Name:    [ qtox ]
-  Version: [ 1.13.0 ]
-  Release: [ 1 ]
-  License: [ GPL v3 ]
-  Group:   [ checkinstall ]
-  Architecture: [ amd64 ]
-  Source location: [ build ]
-  Alternate source location: [  ]
- Requires: [  ]
- Provides: [ qtox ]
- Conflicts: [  ]
- Replaces: [  ]

Enter a number to change any of them or press ENTER to continue: 

Then, you can see files when will be installed … or not, and finish build .deb package.

/home
/home/tele
/home/tele/NIC
/home/tele/NIC/bin
/home/tele/NIC/bin/qtox
/home/tele/NIC/share
/home/tele/NIC/share/appdata
/home/tele/NIC/share/appdata/qTox.appdata.xml
/home/tele/NIC/share/applications
/home/tele/NIC/share/applications/qtox.desktop
/home/tele/NIC/share/icons
/home/tele/NIC/share/icons/hicolor
/home/tele/NIC/share/icons/hicolor/128x128
/home/tele/NIC/share/icons/hicolor/128x128/apps
/home/tele/NIC/share/icons/hicolor/128x128/apps/qtox.png
...

You probably don't want them to be included in the package.
Do you want me to list them?  [n]: n

**********************************************************************

 Done. The new package has been saved to

 /home/tele/Pulpit/test/Qtox/qTox-1.13.0/build/qtox_1.13.0-1_amd64.deb
 You can install it in your system anytime using: 

      dpkg -i qtox_1.13.0-1_amd64.deb

**********************************************************************

Then install .deb package from root.

3. Run app.

You can run app from terminal like this

/home/tele/NIC/bin/qtox or ./qtox but this is not comfortable. So I created icon on Desktop ( for Mate, graphic environment ) which inside text editor looks like this … ``` #!/usr/bin/env xdg-open

[Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[pl_PL]=mate-panel-launcher Name[pl_PL]=QTox Exec=/home/tele/NIC/bin/qtox Comment[pl_PL]=qTox is a powerful Tox client. Name=QTox Comment=QTox is a powerful Tox client. Icon=/home/tele/NIC/share/icons/hicolor/scalable/apps/qtox.svg

Right click on the desktop, click " create activator " 
 fill in the empty fields
and you should have similar file like above.


And it has such permissions ...

$ ls -l | grep QTox -rwxr-xr-x 1 tele tele 321 lis 29 01:49 QTox.desktop


if you need, you can change like this ...

$ chmod 755 qtox.desktop ```

That’s all, I hope your new Qtox works and you’re happy. Have a nice day !
