    <title>Installation of Gjs</title>

    <para>
      First, work around a bug in meson caused by support for Windows NT:
    </para>

    <!-- When scripting, 'ninja install' fails because the 'gjs' symlink is
         generated before 'gjs-console' is installed. This seems to be due
         to adding symbolic link support for Windows NT-based platforms.
         This shouldn't affect us, so let's create the symlink manually
         like we do in other packages.-->

<screen><userinput remap="pre">sed -i '/symlink-gjs.py/s/^/#/g' meson.build</userinput></screen>

    <para>
      Install <application>Gjs</application> by running the following
      commands:
    </para>

<screen><userinput>mkdir gjs-build &amp;&amp;
cd    gjs-build &amp;&amp;

meson --prefix=/usr .. &amp;&amp;
ninja</userinput></screen>

    <para>
      To test the results, issue: <command>ninja test</command>. The
      <application>GTK</application> and <application>Cairo</application>
      tests will fail if not running in an Xorg session. One test,
      <filename>gjs: Scripts/CommandLine</filename>, is known to fail.
      On some systems, up to four tests may fail with an error.
      <!-- Still fails with 1.58.5. -->
    </para>

    <para>
      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>ninja install &amp;&amp;
ln -sfv gjs-console /usr/bin/gjs</userinput></screen>
