a simpler setup. Run:

Either add that to your own <filename>.bash_profile</filename>

Before starting to install the packages in the following pages, remember
|

to execute:

</para>
|

|
|
<screen><userinput>source /etc/profile</userinput></screen>
|
|
|
|
<para>
|
|
Some packages from the KF5 bundle and lxqt packages install files into
|
|
/usr/share, but look in $LXQT_PREFIX/share. In order to have
|
|
applications find these files, create a symlink between these directories.
|
|
Run the following commands as the &root; user:
|
|
</para>
|
|
|
|
<screen role="root"><userinput>source /etc/profile &&
|
|
install -v -dm755 $LXQT_PREFIX &&
|
|
ln -sfv /usr/share $LXQT_PREFIX</userinput></screen>
|
|
|
|
<!--install -v -dm755 $LXQT_PREFIX/share/icons &&-->
|
|
<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"/>,
|
|
<xref linkend="libpwquality"/>, and <xref linkend="sudo"/>, with
|
|
their dependencies.
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build the whole <xref linkend="x-window-system"/> chapter, including
|
|
Wayland support and xcb-utils-xxx packages, with required and
|
|
recommended dependencies, 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 some of the recommended Qt dependencies, namely:
|
|
<xref linkend="double-conversion"/>,
|
|
<xref linkend="libjpeg"/>,
|
|
<xref linkend="libxkbcommon"/>, and
|
|
<xref linkend="sqlite"/>.
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build the required parts of <xref linkend="qt5"/>. To skip all
|
|
modules but the those needed for LXQt, do:
|
|
</para>
|
|
<screen role="nodump"><userinput>ls -Fd qt* | grep / | sed 's/^/-skip /;s@/@@' > tempconf
|
|
sed -ir '/base|tools|x11extras|svg|declarative|wayland/d' tempconf
|
|
./configure <book flags> $(cat tempconf)</userinput></screen>
|
|
<para>
|
|
The time needed to complete the Qt installation is thus reduced to
|
|
around 11 SBU.
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build miscellaneous dependencies (with their required ones):
|
|
<xref linkend="json-glib"/>,
|
|
<xref linkend="libexif"/>,
|
|
<xref linkend="libstatgrab"/>,
|
|
<xref linkend="lm_sensors"/>,
|
|
<xref linkend="menu-cache"/>,
|
|
|
|
<phrase revision="sysv">
|
|
<xref linkend="pm-utils"/>,
|
|
</phrase>
|
|
|
|
<xref linkend="alsa-lib"/>,<!--recommended for pulseaudio, so has to
|
|
be here since we tell to build only required dependencies.-->
|
|
<xref linkend="polkit"/>,
|
|
<xref linkend="pulseaudio"/>, and
|
|
<xref linkend="upower"/>.
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Build KDE frameworks dependencies:
|
|
<xref linkend="extra-cmake-modules"/>,
|
|
<xref linkend="libdbusmenu-qt"/>,
|
|
<xref linkend="plasma-wayland-protocols"/>, and
|
|
<xref linkend="polkit-qt"/>.
|
|
</para>
|
|
</step>
|
|
|
|
<step>
|
|
<para>
|
|
Finally, build some desktop utilities:
|
|
<xref linkend="breeze-icons"/> or other sets of icons,
|
|
<xref linkend="hicolor-icon-theme"/>,
|
|
<xref linkend="desktop-file-utils"/> (needed to update the
|
|
desktop database),
|
|
<xref linkend="shared-mime-info"/> (needed to update the mime
|
|
database),
|
|
<xref linkend="xdg-utils"/> (needs only xmlto), and
|
|
<xref linkend="xdg-user-dirs"/>.
|
|
</para>
