Linux From Scratch - Version 7.0

5.12. Expect-5.45

The Expect package contains a program for carrying out scripted dialogues with other interactive programs.

Approximate build time: 0.1 SBU

Required disk space: 4.1 MB

5.12.1. 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.
