<title>Installation of Bison</title>

<para>Flex contains several known bugs. Fix these with the following patch:</para>

<screen><userinput>patch -Np1 -i ../flex-&flex-version;-debian-fixes-2.patch</userinput></screen>

<para>The GNU autotools detects that the Flex source code has been modified by
the patch, and tries to update the man pages to include those changes, but this
breaks on many systems, and the default pages are fine, so make sure they don't
get renegerated:</para>

<screen><userinput>touch doc/*.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>Now install the package:</para>

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