37 One option is to install <application>KDE Frameworks 5</application>
38 into the <filename class="directory">/usr</filename> hierarchy.
39 This creates a simpler setup but makes it more difficult to try

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