The Expect package contains a program for carrying out scripted dialogues with other interactive programs.
User Notes: http://wiki.linuxfromscratch.org/hlfs/wiki/expect
First, 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
Next, 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 testsuite tools remain sane for
the final builds of our toolchain.
cp -v configure{,.bak}
sed 's:/usr/local/bin:/bin:' configure.bak > configure
Now prepare Expect for compilation:
./configure --prefix=/tools --with-tcl=/tools/lib \
--with-tclinclude=/tools/include --with-x=no
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.
--with-x=no
This tells the configure script not to search for Tk (the Tcl GUI component) or the X Window System libraries, both of which may reside on the host system but will not exist in the temporary environment.
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.
