<title>Installation of Readline</title>

<para>Readline has a number of bugs in it that cause it to not behave the 
way it is expected at times. Fix this behavior with the following
patch:</para>

<screen><userinput>patch -Np1 -i ../readline-&readline-version;-gnu-fixes-1.patch</userinput></screen>

<para>Now prepare Readline for compilation:</para>

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

<para>Compile the package:</para>

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

<para>Install the package:</para>

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

<para>Give Readline's dynamic libraries to a more appropriate permissions:</para>

<screen><userinput>chmod 644 /usr/lib/*.&readline-version;</userinput></screen>

<para>And move them to a more appropriate location:</para>

<screen><userinput>mv /usr/lib/lib{readline,history}.so.4* /lib</userinput></screen>

<para>Because the libraries have been moved, a few symlinks are now pointing to
non-existent files. Recreate those symlinks:</para>

<screen><userinput>ln -sf ../../lib/libhistory.so.4 /usr/lib/libhistory.so
ln -sf ../../lib/libreadline.so.4 /usr/lib/libreadline.so</userinput></screen>
