    <para><application>Xorg</application> is a freely redistributable, 
    open-source implementation of the <application>X</application> Window 
    System. This system provides a client/server interface between display 
    hardware (the mouse, keyboard, and video displays) and the desktop 
    environment, while also providing both the windowing infrastructure and a 
    standardized application interface (API).</para>

    <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 200 
    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, simply install all packages at the cost of extra diskspace.</para>

    <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 Windows 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 Hierarcy Standard for Release 7 of the X Windows 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 
    <parameter>XORG_PREFIX</parameter> 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 
    configure switches for all of the packages.  Create the 
    <parameter>XORG_CONFIG</parameter> variable to use for substitution:</para>

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