    <para>The uClibc package contains the main C library. This library provides
    the basic routines for allocating memory, searching directories, opening and
    closing files, reading and writing files, string handling, pattern matching,
    arithmetic, and so on.</para>

    <note os="a">
      <para>Below we are just telling uClibc to use its default configuration.
      For those for more adventureous, you can use make menuconfig, and
      do a more custom build for your uClibc installation.</para>
    </note>

    <para os="b">The following patch contains the default configurations for
    the architectures covered in this book:</para>

<screen os="c"><userinput>patch -Np1 -i ../&uclibc-configs-patch;</userinput></screen>

   <para os="d">Now we will copy the configuration file best matching this
   build and use that as the base:</para>

<screen os="e"><userinput>cp -v clfs/config.${CLFS_ARCH}.${CLFS_ENDIAN} .config</userinput></screen>

    <para os="f">The config is a basic working system, but there are some
    options that are architecture specifc that need to be set. The following
    command will only bring up items that need a value that we did not
    specify in our Generic config file:</para>

<screen os="g"><userinput>make oldconfig</userinput></screen>

    <para os="h">Compile the package:</para>

<screen os="i"><userinput>make</userinput></screen>

    <para os="l">Install the package:</para>

<screen os="j"><userinput>make PREFIX=${CLFS} install</userinput></screen>
