KF5 can be installed in <filename class="directory">/usr</filename> or

recommend the latter in the BLFS environment.

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>.

It is a good idea to add the following variables to your

system or personal profiles:

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):
|

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 &&

<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.
