Due to recent changes in <command>grep</command> it is essential that
|
|
the installing system be set to a UTF-8 locale. An example
|
|
is <command>export LANG=en_US.UTF-8</command>, but any UTF-8 locale is
|
|
sufficient. Failure to do this will result in a faulty installation.

Some packages from the KDE Frameworks 5 bundle install files into D-Bus
|
|
directories. In order to have D-Bus find those files, the easiest
|
|
way is to create a symlink. Some packages may also install icons from
|
|
the <quote>hicolor</quote> icon set. Since that icon set is used by many
|
|
packages, it is a good idea to create a symlink to the one in <filename
|
|
class="directory">/usr/share</filename> to avoid having multiple
|
|
installations of <xref linkend="hicolor-icon-theme"/>. Run the
|
|
following commands as the <systemitem class="username">root</systemitem>
|
|
user:
|
|
</para>
|
|
|
|
<screen role="root"><userinput>source /etc/profile &&
|
|
install -v -dm755 $LXQT_PREFIX/share/icons &&
|
|
ln -sfv /usr/share/icons/hicolor $LXQT_PREFIX/share/icons &&
|
|
ln -sfv /usr/share/dbus-1 $LXQT_PREFIX/share </userinput></screen>
|
|
|
|
<tip>
|
|
<para>
|
|
Sometimes, the installation paths are hardcoded into installed files.
|
|
This is the reason why <filename class="directory">/opt/lxqt</filename>
|
|
is used as installation prefix instead of <filename
|
|
class="directory">/opt/lxqt-&lxqt-version;</filename>. After installing
|
|
<application>LXQt Desktop</application>, you may rename the directory
|
|
and create a symlink:
|
|
</para>
|
|
|
|
<screen role="root"><userinput>mv /opt/lxqt{,-&lxqt-version;}
|
|
ln -sfv lxqt-&lxqt-version; /opt/lxqt</userinput></screen>
|
|
|
|
<para>
|
|
Later on, you may want to install other versions of <application>LXQt
|
|
Desktop</application>. To do that, just remove the symlink and use
|
|
<filename class="directory">/opt/lxqt</filename> as the prefix again.
|
|
Which version of <application>LXQt Desktop</application> you use
|
|
depends only on where the symlink points. No other reconfiguration will
|
|
be needed.

<title>Notes about building LXQt dependencies</title>
|
|
|
|
<para>
|
|
<application>LXQt</application> obviously needs <xref linkend="qt5"/>,
|
|
but not all Qt5 modules and dependencies are necessary. Since the aim
|
|
of <application>LXQt</application> is to be light weight, it may be
|
|
interesting to cut down the Qt5 overhead, and to build only parts of it.
|
|
To build Qt and LXQT dependencies, the proposed order is the following:
|
|
</para>
|
|
|
|
<procedure>
|
|
<step>
|
|
<para>
|
|
Build <xref linkend="linux-pam"/>, <xref linkend="shadow"/>,
|
|
and <xref linkend="sudo"/>, with their dependencies
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build the whole <xref linkend="x-window-system"/> chapter, with
|
|
Wayland support, and replacing twm vith <xref linkend="openbox"/>
|
|
(and its required dependencies). Some Xorg applications and fonts
|
|
may be omitted, but with a negligible impact on build time and size
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build <xref linkend="gtk2"/> and its required and recommended
|
|
dependencies. GTK+2 is needed for <xref linkend="libfm"/>, and
|
|
brings the <command>gtk-update-icon-cache</command> executable,
|
|
which is needed by libqtxdg
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build required Qt dependencies, and some of the recommended or
|
|
optional dependencies, namely:
|
|
<xref linkend="openssl10"/>,
|
|
<xref linkend="dbus"/>,
|
|
<xref linkend="alsa-lib"/>,
|
|
<xref linkend="pulseaudio"/>, and
|
|
<xref linkend="libxkbcommon"/>
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build the required parts of <xref linkend="qt5"/>. To skip all
|
|
modules but the four needed for LXQt, do:
|
|
</para>
|
|
<screen role="nodump"><userinput>ls -Fd qt* | grep / | sed 's/^/-skip /;s/qt//;s@/@@' > tempconf
|
|
sed -i '/base/d;/tools/d;/x11extras/d;/svg/d' tempconf
|
|
# if you plan to build SDDM, add:
|
|
sed -i '/declarative/d' tempconf
|
|
./configure <book flags> $(cat tempconf)</userinput></screen>
|
|
<para>
|
|
The time needed to complete the Qt installation is thus reduced to
|
|
around 6 SBU
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build miscellaneous dependencies (with their required ones):
|
|
<xref linkend="libexif"/>,
|
|
<xref linkend="libstatgrab"/>,
|
|
<xref linkend="polkit"/>,
|
|
<phrase revision="sysv">
|
|
<xref linkend="consolekit"/> (after polkit),
|
|
<xref linkend="pm-utils"/>,
|
|
</phrase>
|
|
<xref linkend="lm_sensors"/>,
|
|
<xref linkend="upower"/>, and
|
|
<xref linkend="libfm"/>. If <xref linkend="cmake"/> has not been
|
|
built during the preceding steps, build it now
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build KDE frameworks dependencies:
|
|
<xref linkend="extra-cmake-modules"/>,
|
|
<xref linkend="libdbusmenu-qt"/>, and
|
|
<xref linkend="polkit-qt"/>
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Finally, build some desktop utilities:
|
|
<xref linkend="xdg-utils"/> (needs only xmlto),
|
|
<xref linkend="xdg-user-dirs"/>,
|
|
<xref linkend="oxygen-icons5"/> or other sets of icons
|
|
</para>
