    <title>Installation of Readline</title>

    <para>Reinstalling Readline will cause the old libraries to be moved to
    &lt;libraryname&gt;.old. While this is normally not a problem, in some cases
    it can trigger a linking bug in <command>ldconfig</command>. This can be
    avoided by issuing the following two seds:</para>

<screen><userinput remap="pre">sed -i '/MV.*old/d' Makefile.in
sed -i '/{OLDSUFF}/c:' support/shlib-install</userinput></screen>

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

<screen><userinput remap="configure">./configure --prefix=/usr    \
            --disable-static \
            --with-curses    \
            --docdir=/usr/share/doc/readline-&readline-version;</userinput></screen>

      <varlistentry>
        <term><parameter>--with-curses</parameter></term>
        <listitem>
          <para>This option tells Readline that it can find the termcap
               library functions in the curses library, rather than a separate
               termcap library. It allows generating a correct
               <filename>readline.pc</filename> file.</para>

    <para>Now move the dynamic libraries to a more appropriate location
    and fix up some permissions and symbolic links:</para>

<screen><userinput remap="install">mv -v /usr/lib/lib{readline,history}.so.* /lib
chmod -v u+w /lib/lib{readline,history}.so.*
ln -sfv ../../lib/$(readlink /usr/lib/libreadline.so) /usr/lib/libreadline.so
ln -sfv ../../lib/$(readlink /usr/lib/libhistory.so ) /usr/lib/libhistory.so</userinput></screen>

    <para>If desired, install the documentation:</para>

<screen><userinput remap="install">install -v -m644 doc/*.{ps,pdf,html,dvi} /usr/share/doc/readline-&readline-version;</userinput></screen>
