<title>Installation of Gawk</title>

<para>Before installing the Gawk package you have to apply a patch to it
which fixes the following issues:</para>

<itemizedlist>
<listitem><para>Gawk's default location for libexecdir is <filename
class="directory">$prefix/libexecdir/awk</filename>. This location doesn't
comply with FHS (FHS never mentions a directory called
libexecdir).</para></listitem>

<listitem><para>The patch allows us to pass
<emphasis>--libexecdir</emphasis> to the configure script (without gawk
tacking on /awk to the end), so that we can use a more appropriate location
for gawk's libexecdir (<filename class="directory">/usr/bin</filename> in
the book).</para></listitem>

<listitem><para>The default data directory for gawk is <filename
class="directory">$prefix/share/awk</filename>. A package specific
directory should be named after the package and the version (gawk-3.1.1
instead of awk) because there may be more than one awk interpreter on a
system (and more than one version of gawk). The patch changes this to
<filename class="directory">$prefix/share/gawk-3.1.1</filename> to be more
correct.</para></listitem>

<listitem><para>The patch ensures that this directory (<filename
class="directory">$prefix/share/gawk-3.1.1</filename>) is removed along
with its contents on a make uninstall.</para></listitem>
</itemizedlist>

<para><screen><userinput>patch -Np1 -i ../gawk-&gawk-patch-version;.patch</userinput></screen></para>

<para>Prepare Gawk to be compiled:</para>

<para><screen><userinput>./configure --prefix=/usr --libexecdir=/usr/bin</userinput></screen></para>

<para>Continue with compiling the package:</para>

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

<para>Finish installing the package:</para>

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