Xorg-6.9.0

The Xorg sources must be patched in order to avoid a race condition with the luit program. Additionally, Xorg contains 5 security vulnerabilities. Fix these issues with the following commands:

patch -Np1 -i ../xorg-6.9.0-luit_race-1.patch &&
patch -Np1 -i ../xorg-6.9.0-security-4.patch

Additionally, if you choose to install Xorg to any prefix other than /usr/X11R6, the luit package needs another correction to fix a hard coded path. Execute the following command:

sed -i 's@/usr/X11R6@</usr>@' programs/luit/parser.h

Xorg insists on putting its boot and profile scripts into the /etc directory even if specifically told not to compile anything Xprint server or client related (see host.def below). The following command will suppress any such modifications:

sed -i '/^SUBDIRS =/s/ etc$//' programs/Xserver/Xprint/Imakefile

When building Xorg, you should create a shadow directory of symbolic links for the compiled code. To do that, first make lndir. Starting from the xc directory:

pushd config/util &&
make -f Makefile.ini lndir
popd

Now create the shadow tree:

mkdir ../xcbuild &&
cd ../xcbuild &&
../xc/config/util/lndir ../xc

The next step is to create the config/cf/host.def file. The documentation for Xorg indicates that the application will build without a host.def file, but the included libraries for Fontconfig and FreeType2 do not build properly on a base LFS system. Therefore, you must specify that these libraries, as well as others, should be imported from the system.

Note

config/cf/host.def is a C file, not a shell script. Ensure the comments delimited by /* ... */ are balanced when modifying the file.

cat > config/cf/host.def << "EOF"

There are several other options that you may want to consider. A well documented example file is config/cf/xorgsite.def.

Install Xorg by running the following commands:

sed -i -e "s@^#include <linux/config.h>@/* & */@" \
    `grep -lr linux/config.h *` &&
( make World 2>&1 | tee xorg-compile.log && exit $PIPESTATUS )

This package does not come with a test suite.

Now, as the root user:

make install &&
make install.man

If you've installed Xorg in the default prefix listed above, run the following commands as the root user:

ln -v -s ../X11R6/bin /usr/bin/X11 &&
ln -v -s ../X11R6/lib/X11 /usr/lib/X11 &&
ln -v -s ../X11R6/include/X11 /usr/include/X11

The Xorg fonts have been installed outside of Fontconfig's default search path of /usr/share/fonts. In order for Fontconfig to find the installed TrueType fonts, you should make symlinks to their directories. Assuming you've installed Xorg in the default prefix, run the following commands as the root user:

install -v -d -m755 /usr/share/fonts &&
ln -svn /usr/X11R6/lib/X11/fonts/TTF /usr/share/fonts/X11-TTF

You should now continue on to the X Window System Components section to complete the configuration of Xorg.
