37 One option is to install <application>KDE Frameworks 5</application>

150 <para>
151 Several <application>KDE Frameworks 5</application> packages install
152 files into <application>D-Bus</application> directories. When installing
153 <application>KDE Frameworks 5</application> in a location other than
154 <filename class="directory">/usr</filename>,
155 <application>D-Bus</application> needs to be able to find these files.
156 The easiest way to achieve this is to create the following symlinks (as
157 the <systemitem class="username">root</systemitem> user):
158 </para>
159
160<screen role="root"><userinput>install -v -dm755 $KF5_PREFIX/{etc,share} &amp;&amp;
161ln -sfv /etc/dbus-1 $KF5_PREFIX/etc &amp;&amp;
162ln -sfv /usr/share/dbus-1 $KF5_PREFIX/share</userinput></screen>
163
164 <para>
165 Some packages may also install icons from the "hicolor" icon set. Since that
166 icon set is used by many packages, it is a good idea to create a
167 symlink to the one in <filename class="directory">/usr/share</filename>
168 to avoid having multiple installations of <xref linkend="hicolor-icon-theme"/>.
169 Run the following commands as the <systemitem class="username">root</systemitem>
170 user:
171 </para>
172
173<screen role="root"><userinput>install -v -dm755 $KF5_PREFIX/share/icons &amp;&amp;
174ln -sfv /usr/share/icons/hicolor $KF5_PREFIX/share/icons</userinput></screen>
175
176 <tip>
177 <para>
178 Sometimes, the installation paths are hardcoded into installed files.
179 This is the reason why <filename class="directory">/opt/kf5</filename>
180 is used as installation prefix instead of <filename
181 class="directory">/opt/kf5-&kf5-version;</filename>. After installing
182 <application>KDE Frameworks</application>, you may rename the directory
183 and create a symlink:
184 </para>
185
186<screen role="root"><userinput>mv /opt/kf5{,-&kf5-version;}
187ln -sfv kf5-&kf5-version; /opt/kf5</userinput></screen>
188
189 <para>
190 Later on, you may want to install other versions of
191 <application>KDE Frameworks 5</application>. To do that, just remove
192 the symlink and use <filename class="directory">/opt/kf5</filename>
193 as the prefix again. Which version of
194 <application>KDE Frameworks 5</application> you use depends only on
195 where the symlink points. No other reconfiguration will be needed.
