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

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