      <application>WebKit</application> takes a long time to compile, so if you
      have a multicore CPU it can be useful to speed up the build by running
      make with multiple jobs.
    </para>

    <para>
      If you want to run make with just one core, install
      <application>WebKit</application> by running the following commands:

<screen><userinput>./configure --prefix=/usr --enable-introspection &amp;&amp;
make</userinput></screen>

    <para>
      If you have a multicore CPU and want to run make with multiple jobs

    <title>Command Explanations</title>

    <para>
      <option>--enable-introspection</option>: This option enables support for
      <application>Gobject Introspection</application> and is required for a
      <application>GNOME</application> Desktop. If you don't have
      <application>Gobject Introspection</application> installed and don't want
      to install <application>GNOME</application> remove this option.
    </para>

    <para>
      <command>error_count=0; until make ...</command>: Sadly
      there are race conditions in the makefiles that will cause the build to
      fail if you run make with multiple jobs. This simple hack works around
      that problem by using <command>until</command> to keep running
      <command>make</command> until it succeeds. The variable
      <envar>error_count</envar> is incremented each time an error occurs and is
      checked to ensure that no more than 5 errors occur. This is so that if an
      error occurs that is <emphasis>not</emphasis> due to a race condition then
      it will not keep repeating <command>make</command> forever.
      <command>$(getconf _NPROCESSORS_ONLN)</command> prints the number of cores
      your computer seems to have. If you would prefer, you can use any positive
      integer such as 4.
    </para>

    <para>
      <option>--with-gtk=2.0</option>: This option forces
      <application>WebKit</application> to compile against
      <application>GTK+ 2</application>, even if
      <application>GTK+ 3</application> is also installed. With
      <application>GTK+ 2</application>, everything
      <application>Webkit</application> installs is suffixed with 1.0. When it
      is compiled against <application>GTK+ 3</application> everything it
      installs is suffixed with 3.0. Both versions can be installed alongside
      one another with no namespace conflicts.
