title: Building Qutim using Qt5

short: building-qutim-using-qt5

description: <a href="http://qutim.org">Qutim</a> is a multiprotocol and cross platform messenger. It is written on <code>CPP</code> using Qt library. The project is actively developed. In this paper I will say about building this package in Archlinux using Qt5 library (instead of Qt4 which is used in current AUR packages).

<h2><a name="problems" class="anchor" href="#problems"><span class="octicon octicon-link"></span></a>What's wrong?</h2>
|

<p>This package uses <a href="http://qt-project.org/wiki/qbs">qbs</a> for building, which is a bit strange IMHO. A package, which is necessary for building, is <a href="https://aur.archlinux.org/packages/qbs-git/">in AUR </a>. I recommend to use git version of the package. When I asked Andrea Scarpino (who maintains KDE and Qt packages into the official repos) about qbs, he told me "we will support it in time". And I agree with him, the project seems to be a little unstable.</p>

<p>Firstly we find Qt libraries. Then we find toolchains (such as compilers). And next we must insert a toolchain into Qt profile (for example, we need <code>clang</code> toolchain):</p>

{% highlight bash %}

sed 's/clang\\/qt-5-2-0\\/g' -i ~/.config/QtProject/qbs.conf

|

<p>And there are other ways. You may edit the file manually or use <code>qbs-config-ui</code> or <code>qbs-config</code>.</p>
|
||||
<p>So, we have created the configuration file and put it into build directory:</p>
