<title>KDE Frameworks 5 Pre-installation Configuration</title>
<indexterm zone="kf5">
<primary sortas="a-kf5">KDE Frameworks</primary>
</indexterm>
<para>KF5 can be installed in /usr or /opt/kf5. The BLFS editors
recommend the latter in the BLFS environment.
</para>
<sect2>
<title>Installing in /usr</title>
<para>
One option is to install <application>KDE Frameworks 5</application>
into the <filename class="directory">/usr</filename> hierarchy.
This creates a simpler setup but makes it more difficult to try
multiple versions of <application>KDE Frameworks</application>.
</para>
<screen><userinput>export KF5_PREFIX=/usr</userinput></screen>
<para>
It is a good idea to add the following variables to your
system or personal profiles:
</para>
<screen role="root"><userinput>cat &gt;&gt; /etc/profile.d/qt5.sh &lt;&lt; "EOF"
<literal># Begin kf5 extension for /etc/profile.d/qt5.sh
pathappend /usr/lib/qt5/plugins QT_PLUGIN_PATH
pathappend $QT5DIR/lib/plugins QT_PLUGIN_PATH
pathappend /usr/lib/qt5/qml QML2_IMPORT_PATH
pathappend $QT5DIR/lib/qml QML2_IMPORT_PATH
# End extension for /etc/profile.d/qt5.sh</literal>
EOF
cat &gt; /etc/profile.d/kf5.sh &lt;&lt; "EOF"
<literal># Begin /etc/profile.d/kf5.sh
export KF5_PREFIX=/usr
# End /etc/profile.d/kf5.sh</literal>
EOF</userinput></screen>
<note><para>If <application>qt5</application> was installed in /usr, the
$QT5DIR/lib/ portions of the above paths may need to be changed to
$QT5DIR/lib/qt5/.</para></note>
<warning>
<para>
If <application>KDE4</application> is installed in
<filename class="directory">/usr</filename>, some packages
from this chapter might overwrite some programs installed
by <application>KDE4</application> packages.
</para>

<title>Installing in /opt</title>
<para>
A method of building multiple versions installs
<application>KDE Frameworks 5</application> in the
<filename class="directory">/opt</filename> hierarchy:
</para>
<screen><userinput>export KF5_PREFIX=/opt/kf5</userinput></screen>
<para>
If you are not installing <application>KDE Frameworks 5</application>
in <filename class="directory">/usr</filename>, you will need to
make some additional configuration changes. Best practice is to add
those to your system or personal profile:
</para>
<screen role="root"><userinput>cat &gt; /etc/profile.d/kf5.sh &lt;&lt; "EOF"
<literal># Begin /etc/profile.d/kf5.sh
export KF5_PREFIX=/opt/kf5
pathappend $KF5_PREFIX/bin PATH
pathappend $KF5_PREFIX/lib/pkgconfig PKG_CONFIG_PATH
pathappend $KF5_PREFIX/etc/xdg XDG_CONFIG_DIRS
pathappend $KF5_PREFIX/share XDG_DATA_DIRS
pathappend $KF5_PREFIX/lib/plugins QT_PLUGIN_PATH
pathappend $KF5_PREFIX/lib/qml QML2_IMPORT_PATH
pathappend $KF5_PREFIX/lib/python&python2-majorver;/site-packages PYTHONPATH
pathappend $KF5_PREFIX/share/man MANPATH
# End /etc/profile.d/kf5.sh</literal>
EOF
cat &gt;&gt; /etc/profile.d/qt5.sh &lt;&lt; "EOF"
<literal># Begin Qt5 changes for KF5
pathappend $QT5DIR/plugins QT_PLUGIN_PATH
pathappend $QT5DIR/qml QML2_IMPORT_PATH
# End Qt5 changes for KF5</literal>
EOF</userinput></screen>
<para>
Expand your <filename>/etc/ld.so.conf</filename> file:
</para>
<screen role="root"><userinput>cat &gt;&gt; /etc/ld.so.conf &lt;&lt; "EOF"
<literal># Begin KF5 addition
/opt/kf5/lib
# End KF5 addition</literal>
EOF</userinput></screen>
<indexterm zone="kf5-intro">

</indexterm>
<para>
Several <application>KDE Frameworks 5</application> packages install
files into <application>D-Bus</application> directories. When installing
<application>KDE Frameworks 5</application> in a location other than
<filename class="directory">/usr</filename>,
<application>D-Bus</application> needs to be able to find these files.
The easiest way to achieve this is to create the following symlinks (as
the <systemitem class="username">root</systemitem> user):
</para>
<screen role="root"><userinput>install -v -dm755 $KF5_PREFIX/{etc,share} &amp;&amp;
ln -sfv /etc/dbus-1 $KF5_PREFIX/etc &amp;&amp;
ln -sfv /usr/share/dbus-1 $KF5_PREFIX/share</userinput></screen>
<para>
Some packages may also install icons from the "hicolor" icon set. Since that
icon set is used by many packages, it is a good idea to create a
symlink to the one in <filename class="directory">/usr/share</filename>
to avoid having multiple installations of <xref linkend="hicolor-icon-theme"/>.
Run the following commands as the <systemitem class="username">root</systemitem>
user:
</para>
<screen role="root"><userinput>install -v -dm755 $KF5_PREFIX/share/icons &amp;&amp;
ln -sfv /usr/share/icons/hicolor $KF5_PREFIX/share/icons</userinput></screen>
<tip>
<para>
Sometimes, the installation paths are hardcoded into installed files.
This is the reason why <filename class="directory">/opt/kf5</filename>
is used as installation prefix instead of <filename
class="directory">/opt/kf5-&kf5-version;</filename>. After installing
<application>KDE Frameworks</application>, you may rename the directory
and create a symlink:
</para>
<screen role="root"><userinput>mv /opt/kf5{,-&kf5-version;}
ln -sfv kf5-&kf5-version; /opt/kf5</userinput></screen>
<para>
Later on, you may want to install other versions of
<application>KDE Frameworks 5</application>. To do that, just remove
the symlink and use <filename class="directory">/opt/kf5</filename>
as the prefix again. Which version of
<application>KDE Frameworks 5</application> you use depends only on
where the symlink points. No other reconfiguration will be needed.
