 <title>Re-installation of GCC</title>
 
-<para>The tools required to test GCC and Binutils are installed now: Tcl,
-Expect and DejaGNU. Therefore we can now rebuild GCC and Binutils, linking
-them against the new Glibc, and test them properly (if running the test suites
-in this chapter). One thing to note, however, is that these test suites are
-highly dependent on properly functioning pseudo terminals (PTYs) which are
-provided by your host. These days, PTYs are most commonly implemented via the
-<systemitem class="filesystem">devpts</systemitem> file system. You can quickly check if your host
-system is set up correctly in this regard by performing a simple test:</para>
+<para>Check if there is PTYs for the test suites:</para>
 
 <screen><userinput>expect -c "spawn ls"</userinput></screen>
 
-<para>The response might be:</para>
-
-<blockquote><screen><computeroutput>The system has no more ptys.  Ask your system administrator to create more.</computeroutput></screen></blockquote>
-
-<para>If you receive the above message, your host doesn't have its PTYs set up
-properly. In this case there is no point in running the test suites for GCC
-and Binutils until you are able to resolve the issue. You can consult the LFS
-Wiki at <ulink url="&wiki-root;"/> for more information on how to get PTYs
-working.</para>
-
-<para>This time we will build both the C and the C++ compilers, so you'll have
-to unpack both the core and the g++ tarballs (and testsuite too, if you want to
-run the tests). Unpacking them in your working directory, they will all unfold

-<para>The first patch disables the GCC <command>fixincludes</command> script. We
-mentioned this briefly earlier, but a slightly more in-depth explanation of
-the fixincludes process is warranted here. Under normal circumstances, the GCC
-<command>fixincludes</command> script scans your system for header files that need to be fixed. It
-might find that some Glibc header files on your host system need to be fixed,
-fix them and put them in the GCC private include directory. Then, later on in
-<xref linkend="chapter-building-system"/>, after we've installed the newer
-Glibc, this private include directory would be searched before the system
-include directory, resulting in GCC finding the fixed headers from the host
-system, which would most likely not match the Glibc version actually used for
-the LFS system.</para>
-
-<para>The second patch changes GCC's default location of the dynamic linker
-(typically <filename>ld-linux.so.2</filename>). It also removes
-<filename class="directory">/usr/include</filename> from GCC's include search
-path. Patching now rather than adjusting the specs file after installation
-ensures that our new dynamic linker gets used during the actual build of GCC.

 <title>Host system requirements</title>
 <?dbhtml filename="hostreqs.html"?>
 
-<para>Due to the experimental nature of the current book, the host must be
-running at <emphasis>least</emphasis> a 2.6.2 kernel compiled with GCC-3.0 or
-higher. There are two main reasons for the high requirement.  Firstly, we make
-use of the Native Posix Threading Library (NPTL) whose testsuite will segfault
-if the host's kernel hasn't been compiled with GCC-3.0 or later.  Secondly, the
-2.6.2 or later version of the kernel is required for the use of Udev. Udev
-creates devices dynamically by reading from the
-<systemitem class="filesystem">sysfs</systemitem> file system. Only very
-recently has support for this file system been implemented in most of the kernel
-drivers, however. We must be sure that all the critical system devices get
-created properly.</para>
-
-<para>In order to check that your host kernel meets the requirements outlined
-above, you can run the following command:</para>
-
-<screen><userinput>cat /proc/version</userinput></screen>
-
-<para>This will produce output similar to:</para>
-
-<blockquote><screen><computeroutput>Linux version 2.6.2 (user@host) (gcc version 3.4.0) #1 Tue Apr 20 21:22:18 GMT 2004</computeroutput></screen></blockquote>
-
-<para>If the results of the above command state that your host kernel wasn't
-compiled using a GCC-3.0 (or later) compiler, you will need to compile one
-yourself, and reboot your host to use the newly compiled kernel. Instructions
-for compiling the kernel and configuring the bootloader (assuming your host uses
-GRUB) are given in <xref linkend="chapter-bootable"/>.</para>

 <title>Introduction</title>
 <?dbhtml filename="introduction.html"?>
 
-<para>In this chapter we will compile and install a minimal
-Linux system. This system will contain just enough tools to be able
-to start constructing the final LFS system in the next chapter and allow
-a working environment with a little more user convenience than a minimum
-environment.</para>
-
-<para>The building of this minimal system is done in two steps: first we
-build a brand-new and host-independent toolchain (compiler, assembler,
-linker, libraries, and a few useful utilities), and then use this to build all the other essential
-tools.</para>
-
-<para>The files compiled in this chapter will be installed under the
-<filename class="directory">$LFS/tools</filename> directory
-to keep them separate from the files installed in the next chapter and your host's production directories.
-Since the packages compiled here are merely temporary, we don't want
-them to pollute the soon-to-be LFS system.</para>
-
-<para>Before issuing the build instructions for a package, you are expected to
-have already unpacked it (explained shortly) as user <emphasis>lfs</emphasis>,
-and to have performed a <userinput>cd</userinput> into the created directory.
-The build instructions assume that you are using the <command>bash</command>
-shell.</para>
-
-<para>Several of the packages are patched before compilation, but only when
-the patch is needed to circumvent a problem. Often the patch is needed in
-both this and the next chapter, but sometimes in only one of them. Therefore,
-don't worry when instructions for a downloaded patch seem to be missing. Also,
-when applying a patch, you'll occasionally see warning messages about
-<emphasis>offset</emphasis> or <emphasis>fuzz</emphasis>. These warnings are
-nothing to worry about, as the patch was still successfully applied.</para>
-
-<para>During the compilation of most packages you will see many warnings
-scroll by on your screen. These are normal and can safely be ignored. They are
-just what they say they are: warnings -- mostly about deprecated, but not
-invalid, use of the C or C++ syntax. It's just that C standards have changed
-rather often and some packages still use the older standard, which is not
-really a problem.</para>
-
-<para>After installing each package you should delete its source and build
-directories, <emphasis>unless</emphasis> told otherwise. Deleting the sources
-saves space, but also prevents mis-configuration when the same package is
-reinstalled further on. Only for three packages you will need to keep the
-source and build directories around for a while, so their contents can be used
-by later commands. Do not miss the reminders.</para>
-
-<para>Now first check that your LFS environment variable is set up
-properly:</para>
-
-<screen><userinput>echo $LFS</userinput></screen>
-
-<para>Make sure the output shows the path to your LFS partition's mount
-point, which is <filename class="directory">/mnt/lfs</filename> if you
-followed our example.</para>
+<para>See testing.</para>
