9.3. Expect-5.43.0

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

9.3.1. Installation of Expect

The following sed tells configure to look for libraries in ${libdir}, not just in /tools/lib:

sed -i '/EXP_LIB_SPEC=/s@${exec_prefix}/lib@${libdir}@' configure

Fix a bug that can result in false failures during the GCC test suite run:

patch -Np1 -i ../expect-5.43.0-spawn-2.patch

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 testsuite-tools location.
--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 the Tcl source directory.

Build the package:

make

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.

Installed program: expect

Installed library: libexpect-5.43.a

expect	Communicates with other interactive programs according to a script
`libexpect-5.43.a`	Contains functions that allow Expect to be used as a Tcl extension or to be used directly from C or C++ (without Tcl)
