206 | Some packages may also install icons from the "hicolor" icon set. Since that

208 | symlink to the one in <filename class="directory">/usr/share</filename>

209 | to avoid having multiple installations of <xref linkend="hicolor-icon-theme"/>.

219 | Sometimes, the installation paths are hardcoded into installed files.
|
---|
220 | This is the reason why <filename class="directory">/opt/kf6</filename>
|
---|
221 | is used as installation prefix instead of <filename
|
---|
222 | class="directory">/opt/kf6-&kf6-version;</filename>. After installing
|
---|
223 | <application>KDE Frameworks</application>, you may rename the directory
|
---|
224 | and create a symlink:
|
---|
225 | </para>
|
---|
226 |
|
---|
227 | <screen role="root"><userinput>mv /opt/kf6{,-&kf6-version;}

|
---|
230 | <para>
|
---|
231 | Later on, you may want to install other versions of
|
---|
232 | <application>KDE Frameworks</application>. To do that, just remove
|
---|
233 | the symlink and use <filename class="directory">/opt/kf6</filename>
|
---|
234 | as the prefix again. Which version of
|
---|
235 | <application>KDE Frameworks</application> you use depends only on
|
---|
236 | where the symlink points. No other reconfiguration will be needed.
