    <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. One of the
      major users of <application>Qt</application> is <application>KDE
      Frameworks 5 (KF5)</application>.

    <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 rename
        the directory and create a symlink:
      </para>

<screen role="root"><userinput>mkdir /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
        and use <filename class="directory">/opt/qt5</filename> as the
        prefix again. 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></note>

  <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 /usr 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 /usr, the directories need to
        be specified explicitly.  In this case, set QT5PREFIX=/usr and add
        the following to the configure arguments below:
