<para>First, fix a bug that can result in false failures during the GCC test
suite run:</para>
<screen><userinput remap="pre">patch -Np1 -i ../&expect-spawn-patch;</userinput></screen>
<para>Next, fix a bug that is a result of recent Tcl changes:</para>
<screen><userinput remap="pre">patch -Np1 -i ../&expect-tcl-patch;</userinput></screen>
<para>Next, force Expect's configure script to use <filename>/bin/stty</filename>
instead of a <filename>/usr/local/bin/stty</filename> it may find on the host system.
This will ensure that our testsuite tools remain sane for the final builds of our
toolchain:</para>
<screen><userinput remap="pre">cp -v configure{,.orig}
sed 's:/usr/local/bin:/bin:' configure.orig > configure</userinput></screen>
<para>Now prepare Expect for compilation:</para>
<screen><userinput remap="configure">./configure --prefix=/tools --with-tcl=/tools/lib \
--with-tclinclude=/tools/include --with-x=no</userinput></screen>
<variablelist>
<title>The meaning of the configure options:</title>
<varlistentry>
<term><parameter>--with-tcl=/tools/lib</parameter></term>
<listitem>
<para>This ensures that the configure script finds the Tcl
installation in the temporary tools location instead of possibly
locating an existing one on the host system.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><parameter>--with-tclinclude=/tools/include</parameter></term>
<listitem>
<para>This explicitly tells Expect where to find Tcl's internal
headers. Using this option avoids conditions where
<command>configure</command> fails because it cannot automatically
discover the location of Tcl's headers.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><parameter>--with-x=no</parameter></term>
<listitem>
<para>This tells the configure script not to search for Tk (the
Tcl GUI component) or the X Window System libraries, both of which
may reside on the host system but will not exist in the temporary
environment.</para>
</listitem>
</varlistentry>
</variablelist>
<para>Build the package:</para>
<screen><userinput remap="make">make</userinput></screen>
<para>To test the results, issue:</para>
<screen><userinput remap="test">make test</userinput></screen>
<para>Note that the Expect test suite is known to experience failures under
certain host conditions that are not within our control. Therefore,
test suite failures here are not surprising and are not considered
critical.</para>
<para>Install the package:</para>
<screen><userinput remap="install">make SCRIPTS="" install</userinput></screen>
<variablelist>
<title>The meaning of the make parameter:</title>
<varlistentry>
<term><parameter>SCRIPTS=""</parameter></term>
<listitem>
<para>This prevents installation of the supplementary Expect
scripts, which are not needed.</para>
