165 | Several <application>KDE Frameworks 5</application> packages install
|
---|
166 | files into <application>D-Bus</application> directories. When installing
|
---|
167 | <application>KDE Frameworks 5</application> in a location other than
|
---|
168 | <filename class="directory">/usr</filename>,
|
---|
169 | <application>D-Bus</application> needs to be able to find these files.
|
---|
170 | The easiest way to achieve this is to create the following symlinks (as
|
---|
171 | the <systemitem class="username">root</systemitem> user):
|
---|
172 | </para>
|
---|
173 |
|

174 | <screen role="root"><userinput>install -v -dm755 $KF5_PREFIX/{etc,share} &&

---|
175 | ln -sfv /etc/dbus-1 $KF5_PREFIX/etc &&
|
---|
176 | ln -sfv /usr/share/dbus-1 $KF5_PREFIX/share</userinput></screen>

178 | <para>
|
---|
179 | Some packages may also install icons from the "hicolor" icon set. Since that
|
---|
180 | icon set is used by many packages, it is a good idea to create a
|
---|
181 | symlink to the one in <filename class="directory">/usr/share</filename>
|
---|
182 | to avoid having multiple installations of <xref linkend="hicolor-icon-theme"/>.
|
---|
183 | Run the following commands as the <systemitem class="username">root</systemitem>
|
---|
184 | user:
|
---|
185 | </para>
|
---|
186 |
|
---|
187 | <screen role="root"><userinput>install -v -dm755 $KF5_PREFIX/share/icons &&
|
---|
188 | ln -sfv /usr/share/icons/hicolor $KF5_PREFIX/share/icons</userinput></screen>
|
---|
189 |
|
---|
190 | <tip>
|
---|
191 | <para>
|
---|
192 | Sometimes, the installation paths are hardcoded into installed files.
|
---|
193 | This is the reason why <filename class="directory">/opt/kf5</filename>
|
---|
194 | is used as installation prefix instead of <filename
|
---|
195 | class="directory">/opt/kf5-&kf5-version;</filename>. After installing
|
---|
196 | <application>KDE Frameworks</application>, you may rename the directory
|
---|
197 | and create a symlink:
|
---|
198 | </para>
|
---|
199 |
|
---|
200 | <screen role="root"><userinput>mv /opt/kf5{,-&kf5-version;}
|
---|
201 | ln -sfv kf5-&kf5-version; /opt/kf5</userinput></screen>
|
---|
202 |
|
---|
203 | <para>
|
---|
204 | Later on, you may want to install other versions of
|
---|
205 | <application>KDE Frameworks 5</application>. To do that, just remove
|
---|
206 | the symlink and use <filename class="directory">/opt/kf5</filename>
|
---|
207 | as the prefix again. Which version of
|
---|
208 | <application>KDE Frameworks 5</application> you use depends only on
|
---|
209 | where the symlink points. No other reconfiguration will be needed.
