Cross-Compiled Linux From Scratch - Version GIT-20170803-Sparc64-Multilib

Chapter 9. Constructing Testsuite Tools

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 \
    --libdir=/tools/lib64

The meaning of the configure options:

--with-tcl=/tools/lib64

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

9.3.2. Contents of Expect
