17 <title>Installation of Expect</title>
19 <para>First apply a patch:</para>
21 <screen><userinput>patch -Np1 -i ../&expect-patch;</userinput></screen>
23 <para>This fixes a bug in Expect that can result in bogus failures during the
24 GCC test suite run.</para>
26 <para>Now prepare Expect for compilation:</para>
28 <screen><userinput>./configure --prefix=/tools --with-tcl=/tools/lib --with-x=no</userinput></screen>
30 <para>The meaning of the configure options:</para>
33 <listitem><para><userinput>--with-tcl=/tools/lib</userinput>: This ensures that
34 the configure script finds the Tcl installation in our temporary tools location.
35 We don't want it to find an existing one that may possibly reside on the host
36 system.</para></listitem>
38 <listitem><para><userinput>--with-x=no</userinput>: This tells the configure
39 script not to search for Tk (the Tcl GUI component) or the X Window System
40 libraries, both of which may possibly reside on the host system.</para></listitem>
43 <para>Build the package:</para>
45 <screen><userinput>make</userinput></screen>
47 <para>As discussed earlier, we don't recommend running the test suites for the
48 temporary tools here in this chapter. If you still want to run the Expect test
49 suite anyway, the following command will do so. However, you should be aware
50 that the Expect test suite is sometimes known to experience failures under
51 certain host conditions that are not fully understood. Therefore, test suite
52 failures here are not surprising, but are not considered critical:</para>
54 <screen><userinput>make test</userinput></screen>
56 <para>And install:</para>
58 <screen><userinput>make SCRIPTS="" install</userinput></screen>
60 <para>The meaning of the make parameter:</para>
63 <listitem><para><userinput>SCRIPTS=""</userinput>: This prevents installation of
64 the supplementary expect scripts which are not needed.</para></listitem>
67 <para>You can now remove the source directories of both Tcl and Expect.</para>
