circular dependencies. For example, to compile a compiler you need a
compiler.</para>

<para>The first thing to be done in Chapter 5 is build a first pass of the
toolchain, which is made up of Binutils and GCC. The programs from these
packages will be linked statically in order for them to be used independently
of the host system. The second thing to do is build Glibc, the C library.
Glibc will be built with the toolchain programs we just built in the first
pass.</para>
<para>When the first toolchain is built, you will rebuild those three
packages again, this time using the toolchain we just built, rather than
the host system's toolchain. In particular, all programs will be linked
against the new Glibc rather than the host system's Glibc. All subsequent
packages in Chapter 5 will be built and linked using this second toolchain
installation. When this is done (building the second toolchain), the LFS
installation process will no longer depend on the host distribution, with
the exception of the running kernel.</para>
<para>The next thing to do is build a second pass of the toolchain. This
time the toolchain will be dynamically linked against the newly built Glibc.
The remaining Chapter 5 packages are all built using this second pass
toolchain and dynamically linked against the new Glibc. When this is done,
the LFS installation process will no longer depend on the host distribution,
with the exception of the running kernel.</para>
<para>In Chapter 6 the real LFS system will be built. The
chroot (change root) program is used to enter a virtual environment and
