<title>Installation of Flex</title>

<para>Flex contains several known bugs. These can be fixed with the
following patch:</para>

<screen><userinput>patch -Np1 -i ../&flex-fixes-patch;</userinput></screen>

<para>The GNU autotools will detect that the Flex source code has been
modified by the previous patch and tries to update the man page
accordingly.  This does not work on many systems, and the default page is
fine, so make sure it does not get regenerated:</para>

<screen><userinput>touch doc/flex.1</userinput></screen>

<para>Now prepare Flex 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 check</userinput>.</para>

<para>Install the package:</para>

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