37 One option is to install <application>KDE Frameworks 5</application>
38 into the <filename class="directory">/usr</filename> hierarchy.

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