  <title>Introduction</title>

  <para>This chapter shows how to compile and install a minimal Linux
  system. This system will contain just enough tools to start
  constructing the final CLFS system in <xref
  linkend="chapter-building-system"/> and allow a working environment
  with more user convenience than a minimum environment would.</para>

  <para>The tools in this chapter are cross-compiled using the toolchain in
  <filename class="directory">/cross-tools</filename> and will be installed under the
  <filename class="directory">${CLFS}/tools</filename> directory to keep
  them separate from the files installed in <xref
  linkend="chapter-building-system"/> and the host production directories.
  Since the packages compiled here are temporary, we do not want them to
  pollute the soon-to-be CLFS system.</para>

  <para>Check one last time that the <envar>CLFS</envar> environment
  variable is set up properly:</para>

<screen><userinput>echo ${CLFS}</userinput></screen>

  <para>Make sure the output shows the path to the CLFS partition's mount
  point, which is <filename class="directory">/mnt/clfs</filename>, using
  our example.</para>

  <para>During this section of the build you will see several WARNING
  messages like the ones below. It is safe to ignore these messages.</para>

<screen><computeroutput>configure: WARNING: result yes guessed because of cross compilation
configure: WARNING: cannot check WCONTINUED if cross compiling -- defaulting to no</computeroutput></screen>
