    <bridgehead renderas="sect3">Xorg Download and Installation
    Instructions</bridgehead>

    <para>With the modular build system, it is no longer possible to download
    the entire package in a single file.  In fact, there may be as many as
    280 files that need to be fetched from the download location.  To assist
    with such a large task, it is strongly recommended to install
    <xref linkend="wget"/> for downloading the needed files.  A complete
    <application>wget</application> script is available for each section at
    <ulink
    url="http://anduin.linuxfromscratch.org/sources/BLFS/svn/x/wget/"/>.</para>

    <para>Given the number of packages available, deciding which packages you
    need to install for your particular setup may seem a bit overwhelming at
    first.  Take a look at<ulink
    url="http://lists.x.org/archives/xorg-modular/2005-November/000801.html">
    this thread</ulink> to get an idea of what you will need.  If you are
    unsure, you should install all packages at the cost of extra
    disk space.</para>

    <note>
      <para>The installed size of <application>Xorg</application> can
      be reduced considerably by installing only the packages that you will
      need and use. However, the BLFS book cannot account for all dependencies
      and build options for individual <application>Xorg</application>
      packages.  The instructions assume that all packages have been built
      from a particular group unless otherwise noted. A
      <ulink url="http://wiki.linuxfromscratch.org/blfs/wiki/Xorg-7.0.0">
      wiki</ulink> page containing dependency information, for users who wish
      to cut down on the installed size of <application>Xorg</application>, is
      under development.  You are encouraged to add to these
      pages if you discover additional information that may be helpful to
      other users.</para>
    </note>

    <para>Additionally, because of the large number of repetitive commands,
    you are encouraged to script the build.  For most sections, you can use
    the following commands to compile and install all packages in your build
    directory:</para>

<screen>for package in *.tar.bz2
do
  packagedir=`echo $package | sed 's/.tar.bz2//'`
  tar -xf $package &amp;&amp;
  cd $packagedir &amp;&amp;
  ./configure $XORG_CONFIG &amp;&amp;
  make &amp;&amp;
  make install
  if [ $? -ne 0 ]; then
    break #stop the build if the previous command failed
  fi
  cd .. &amp;&amp;
  rm -rf $packagedir
done 2&gt;&amp;1 | tee -a ../xorg-compile.log #log the entire loop</screen>

    <title>Setting up the Xorg Build Environment</title>

      <para>First, you'll need to create a working directory:</para>

<screen><userinput>mkdir xc &amp;&amp;
cd xc</userinput></screen>

    <para>As with previous releases of the X Window System, it may be
    desirable to install <application>Xorg</application> into an alternate
    prefix.  This is no longer common practice among Linux distributions.
    The common installation prefix for <application>Xorg</application> on
    Linux is <filename class="directory">/usr</filename>.  There is no
    standard alternate prefix, nor is there any exception in the current
    revision of the Filesystem Hierarchy Standard for Release 7 of the X
    Window System.  Alan Coopersmith of Sun Microsystems, has recently
    stated "At Sun, we were using
    <filename class="directory">/usr/X11</filename> and plan to stick with
    it."  Only the <filename class="directory">/opt/*</filename> prefix or
    the <filename class="directory">/usr</filename> prefix adhere to the
    current FHS guidelines.</para>

    <para>Choose your installation prefix, and set the
    <envar>XORG_PREFIX</envar> variable with the following
    command:</para>

<screen><userinput>export XORG_PREFIX="<replaceable>[/usr]</replaceable>"</userinput></screen>

    <para>Throughout these instructions, you will use the same three
    <command>configure</command> switches for all of the packages.  Create the
    <envar>XORG_CONFIG</envar> variable to use for substitution:</para>

<screen><userinput>export XORG_CONFIG="--prefix=$XORG_PREFIX --sysconfdir=/etc --localstatedir=/var"</userinput></screen>

    <note>
      <para>If you've decided to use an alternate prefix, be sure to add
      <filename class="directory"><replaceable>[/usr]</replaceable>/lib/pkgconfig</filename>
      to your <envar>PKG_CONFIG_PATH</envar> variable.</para>

      <para>When needed, <application>Xorg</application> creates the directory
      <filename class='directory'>/tmp/.ICE-unix</filename> if it does not
      exist. If this directory is not owned by
      <systemitem class="username">root</systemitem>,
      <application>Xorg</application> delays startup by a few seconds and also
      appends a warning to the logfile. This also affects startup of other
      applications. To improve performance, it is advisable to manually create
      the directory before <application>Xorg</application> uses it. Add the
      file creation to <filename>/etc/sysconfig/createfiles</filename> that is
      sourced by the <filename>/etc/rc.d/init.d/cleanfs</filename> startup
      script.</para>
