Expect-&expect-version; Expect <para>The <application>Expect</application> package contains tools for automating, via scripted dialogues, interactive applications such as <command>telnet</command>, <command>ftp</command>, <command>passwd</command>, <command>fsck</command>, <command>rlogin</command>, and <command>tip</command>. <application>Expect</application> is also useful for testing these same applications as well as easing all sorts of tasks that are prohibitively difficult with anything else. The <application>DejaGnu</application> framework is written in <application>Expect</application>.</para> <segmentedlist> <segtitle>&buildtime;</segtitle> <segtitle>&diskspace;</segtitle> <seglistitem> <seg>&expect-ch5-sbu;</seg> <seg>&expect-ch5-du;</seg> </seglistitem> </segmentedlist> </sect2> <sect2 role="installation"> <title>Installation of Expect First, force Expect's configure script to use /bin/stty instead of a /usr/local/bin/stty it may find on the host system. This will ensure that our test suite tools remain sane for the final builds of our toolchain: cp -v configure{,.orig} sed 's:/usr/local/bin:/bin:' configure.orig > configure Now prepare Expect for compilation: ./configure --prefix=/tools \ --with-tcl=/tools/lib \ --with-tclinclude=/tools/include The meaning of the configure options: --with-tcl=/tools/lib 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. --with-tclinclude=/tools/include This explicitly tells Expect where to find Tcl's internal headers. Using this option avoids conditions where configure fails because it cannot automatically discover the location of Tcl's headers. Build the package: make Compilation is now complete. As discussed earlier, running the test suite is not mandatory for the temporary tools here in this chapter. To run the Expect test suite anyway, issue the following command: make test 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. Install the package: make SCRIPTS="" install The meaning of the make parameter: SCRIPTS="" This prevents installation of the supplementary Expect scripts, which are not needed.
