12
13  <para>All programs compiled in <xref linkend="chapter-cross-tools"/> will
14  be installed under <filename class="directory">$HOME/cross-tools</filename>
15  to keep them separate from the host programs. The programs compiled here are
16  cross tools and will not be a part of the final LFS system. By keeping these
17  programs in a separate directory, they can easily be discarded later after
18  their use.</para>
19
20  <para>Create the required directory by running the following as
21  the <systemitem class="username">lfs</systemitem> user:</para>
22
23<screen><userinput>install -d $HOME/cross-tools</userinput></screen>
24
25  <para>The next step is to create a <filename
26  class="symlink">/cross-tools</filename> symlink on the host system.
27  This will point to the newly-created directory in your home directory.
28  Since normal users will not have permissions to write to the root tree,
29  we need to exit the <command>su</command> and run the symlink command as
30  <systemitem class="username">root</systemitem>:</para>
31
32<screen><userinput>exit
33LFSHOME=`su - lfs -c 'echo $HOME'`
34ln -s $LFSHOME/cross-tools /
35unset LFSHOME
36su - lfs</userinput></screen>
37
38  <para>TO BE REWRITTEN - The created symlink enables the toolchain to be
39  compiled so that
40  it always refers to <filename class="directory">/cross-tools</filename>,
41  meaning that the compiler, assembler, and linker will work both in
42  this chapter and this host architecture and in the next (when we are
43  <quote>chrooted</quote> to the LFS partition).</para>
