    <title>Installation of Coreutils</title>

    <para>The version of the function <quote>futimens</quote> used
    by Coreutils is incompatible with the version that current
    Glibc provides, so we'll rename the function:</para>

<screen><userinput>for file in src/{copy,touch}.c lib/utimens.{c,h} ; do \
   cp -v $file{,.orig}
   sed 's/futimens/gl_&amp;/' $file.orig &gt; $file
done</userinput></screen>

    <para>Prepare Coreutils for compilation:</para>

<screen><userinput>./configure --prefix=/tools</userinput></screen>

    <para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

    <para>To test the results, issue:
    <userinput>make RUN_EXPENSIVE_TESTS=yes check</userinput>. The
    <parameter>RUN_EXPENSIVE_TESTS=yes</parameter> parameter tells the
    test suite to run several additional tests that are considered
    relatively expensive (in terms of CPU power and memory usage) on some
    platforms, but generally are not a problem on Linux.</para>

    <para>Install the package:</para>

<screen><userinput>make install</userinput></screen>

    <para>The above command refuses to install <filename>su</filename>
    because it cannot install it setuid root as a non-privileged user. By
    manually installing it with a different name, we can use it for running
    tests in the final system as a non-privileged user and we keep a possibly
    useful <command>su</command> from our host first place in our PATH. Install
    it with:</para>

<screen><userinput>cp -v src/su /tools/bin/su-tools</userinput></screen>
