<title>Installation of Gawk</title>

<para>Under some circumstances, Gawk-&gawk-version;  attempts to free a chunk
of memory that was not allocated. This bug is fixed by the following patch:</para>

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

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

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

<para>Due to a bug in the <command>./configure</command> script, Gawk fails
to detect certain aspects of locale support in glibc. This
bug leads to, e.g., Gettext testsuite failures. Work around this issue
by appending the missing macro definitions to <filename>config.h</filename>:</para>

<screen><userinput>cat &gt;&gt;config.h &lt;&lt;"EOF"
<literal>#define HAVE_LANGINFO_CODESET 1
#define HAVE_LC_MESSAGES 1</literal>
EOF</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>
