9.3. Expect-5.45

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

9.3.1. Installation of Expect

Now prepare Expect for compilation:

CC="gcc ${BUILD64}" ./configure --prefix=/tools \
   --with-tcl=/tools/lib64 --with-tclinclude=/tools/include  \

The meaning of the configure options:


This ensures that the configure script finds the Tcl installation in the temporary tools location.


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:


Install the package:

make SCRIPTS="" install

The meaning of the make parameter:


This prevents installation of the supplementary expect scripts, which are not needed.
