    <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.
         Invalid with 1.64.3. Make sure you don't have DESTDIR
         set, such as you'd do in an update script.-->

<!--<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 six 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>
