The first step is to create a limited directory hierarchy, so that the programs compiled in <xref linkend="chapter-temporary-tools"/> (as well as glibc and libstdc++ in <xref linkend="chapter-cross-tools"/>) can be installed in their final location. We do this so those temporary programs will be overwritten when the final versions are built in <xref linkend="chapter-building-system"/>.</para> <para>Create the required directory layout by issuing the following commands as <systemitem class="username">root</systemitem>:</para> <screen><userinput>mkdir -pv $LFS/{etc,var} $LFS/usr/{bin,lib,sbin} for i in bin lib sbin; do ln -sv usr/$i $LFS/$i done case $(uname -m) in x86_64) mkdir -pv $LFS/lib64 ;; esac</userinput></screen> <para>Programs in <xref linkend="chapter-temporary-tools"/> will be compiled with a cross-compiler (more details can be found in section <xref linkend="ch-tools-toolchaintechnotes"/>). This cross-compiler will be installed in a special directory, to separate it from the other programs. Still acting as &root;, create that directory with this command:</para> <screen><userinput>mkdir -pv $LFS/tools</userinput></screen> </sect1>
