<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>Xorg-7.0.0 introduced a completely auto-tooled, modular build system.
|
|
The code is otherwise identical to that in the Xorg-6.9.0 release.
|
|
With the new 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, installing <xref linkend="wget"/> is strongly
|
|
recommended for downloading the needed files. A complete
|
|
<application>wget</application> file list is provided for each section
|
|
that includes multiple packages.</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>Even if you intend to download only the necessary packages, you
|
|
should download the wget file lists and use the package versions in the
|
|
file. Newer packages are likely intended for the next release of
|
|
<application>Xorg</application> and have already proved to be
|
|
incompatible with the current version of
|
|
<application>GTK+</application>. 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
|
|
the individual <application>Xorg</application> packages. The
|
|
instructions assume that all packages have been built. A
|
|
<ulink url="http://wiki.linuxfromscratch.org/blfs/wiki/Xorg-&xorg7-version;">wiki</ulink>
|
|
page containing dependency information, is under development. You are
|
|
encouraged to add to these pages if you discover additional information
|
|
that may be helpful to other users who selectively install individual
|
|
packages.</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
|
|
a script with commands similar to the following, to compile and install
|
|
all packages in a wget file list:</para>
|
|
|
|
<screen>bash -e #exit on all errors
|
|
for package in $(cat ../wgetlist.wget)
|
|
do
|
|
packagedir=$(echo $package | sed 's/.tar.bz2//')
|
|
tar -xf $package
|
|
cd $packagedir
|
|
./configure $XORG_CONFIG
|
|
make
|
|
make install
|
|
cd ..
|
|
rm -rf $packagedir
|
|
rm -f $package
|
|
done 2>&1 | tee -a ../xorg-compile.log #log the entire loop</screen>
|
|
|
|
<para>The above shell will exit immediately on error. If it runs to
|
|
completion, you should manually exit the shell before continuing on to
|
|
the next set of instructions.</para>

<title>Setting up the Xorg Build Environment</title>
|
|
|
|
<para>First, you'll need to create a working directory:</para>
|
|
|
|
<screen><userinput>mkdir xc &&
|
|
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><PREFIX></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>
|
|
|
|
<para>If you've decided to use an alternate prefix, be sure to add
|
|
<filename class="directory">
|
|
<replaceable><PREFIX></replaceable>/bin</filename> to your
|
|
<envar>PATH</envar> environment variable and <filename class="directory">
|
|
<replaceable><PREFIX></replaceable>/lib/pkgconfig</filename>
|
|
to your <envar>PKG_CONFIG_PATH</envar> variable. For detailed instructions,
|
|
see <xref linkend="postlfs-config-profile"/>. You should also add
|
|
<filename class="directory">
|
|
<replaceable><PREFIX></replaceable>/lib</filename> to the
|
|
<filename>/etc/ld.so.conf</filename> file.</para>
