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