5.8.2. Contents of Expect
Installed program:
expect
Installed library:
libexpect-5.43.a
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
The config.sub file in this package
does not recognise uClibc. Adjust that with the following command:
cp -v config.sub{,.orig}
sed 's/linux-gnu/linux-uclibc/' config.sub.orig > config.sub
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.
uClibc does not have the stropts.h
header, but it may be found on the host system. The following
command will disable its use so Expect can build with uClibc:
cp -v expect_cf.h{,.orig}
sed 's/#define HAVE_STROPTS_H 1/#undef HAVE_STROPTS_H/' \
expect_cf.h.orig > expect_cf.h
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.
