    <title>Introduction to Qt5</title>

    <para>
      <application>Qt5</application> is a cross-platform application framework
      that is widely used for developing application software with a graphical
      user interface (GUI) (in which cases <application>Qt5</application> is
      classified as a widget toolkit), and also used for developing non-GUI
      programs such as command-line tools and consoles for servers. Two of the
      major users of <application>Qt</application> are <application>KDE
      Frameworks 5 (KF5)</application> and <application>LXQt</application>.
    </para>

    <important>
      <para>
         The installation of the full Qt5 packages is now deprecated for BLFS
         due to the release of <xref linkend="qt6"/>.  This page will probably
         be removed soon depending on the release of new versions of packages
         that still use Qt5.  For those packages, users should use 
         <xref linkend="qt5-alternate"/>.

    <title>Setting the installation prefix</title>

    <bridgehead renderas="sect3">Installing in /opt/qt5</bridgehead>

    <para>
      The BLFS editors recommend installing <application>Qt5</application> in a
      directory other than <filename class="directory">/usr</filename>, ie
      <filename class="directory">/opt/qt5</filename>.  To do this, set the
      following environment variable:
    </para>

<screen><userinput>export QT5PREFIX=/opt/qt5</userinput></screen>

    <tip>
      <para>
        Sometimes the installation paths are hardcoded into installed files.
        This is the reason why <filename class="directory">/opt/qt5</filename>
        is used as installation prefix instead of <filename
        class="directory">/opt/qt-&qt5-version;</filename>. To create a
        versioned <application>Qt5</application> directory, 
        you may create a versioned directory and a symlink:
      </para>

<screen role="root"><userinput>mkdir -pv /opt/qt-&qt5-version;
ln -sfnv qt-&qt5-version; /opt/qt5</userinput></screen>

      <para>
        Later on, you may want to install other versions of
        <application>Qt5</application>. To do that, just remove the symlink,
        create the new versioned directory, and recreate the 
        <filename class="directory">/opt/qt5</filename> symlink again before
        building the new version.
        Which version of <application>Qt5</application> you
        use depends only on where the symlink points.
      </para>
    </tip>

    <note>
      <para>
        If <xref linkend="qca"/> has been installed and you are
        reinstalling or updating this package, then
        <application>qca</application> will need to be reinstalled.
      </para>

  <sect2 role="installation">
    <title>Installation of Qt5</title>

    <warning>
      <para>
        If <application>Qt5</application> is being reinstalled into the
        same directory as an existing instance, run the commands done by
        <systemitem class="username">root</systemitem>, such as
        <command>make install</command>, from a console or non-Qt5 based
        window manager. It overwrites <application>Qt5</application>
        libraries that should not be in use during the install process.
      </para>
    </warning>

    <caution>
      <para>
        If you did not install some of the recommended dependencies, examine
        <command>./configure --help</command> output to check how to disable
        them or use internal versions bundled in the source tarball.
      </para>
    </caution>

    <note>
      <para>
        The build time and space required for the full
        <application>Qt5</application> is quite long. The instructions below
        do not build the tutorials and examples. Removing the
        <parameter>-nomake</parameter> line will create a complete build.
      </para>
    </note>

    <note>
      <para>
        The BLFS editors do not recommend installing
        <application>Qt5</application> into the
        <filename class="directory">/usr</filename> hierarchy because it
        becomes difficult to find components and to update to a new version.
        If you do want to install <application>Qt5</application> in
        <filename class="directory">/usr</filename>, the directories need to
        be specified explicitly.  In this case, set
        <envar>QT5PREFIX=/usr</envar> and add the following to the configure
        arguments below:
      </para>

      The patch is supposed to be used in a git repository. Otherwise some
