The Expect package contains a program for carrying out scripted dialogues with other interactive programs.
First, fix a bug that can result in false failures during the GCC test suite run:
patch -Np1 -i ../expect-5.43.0-spawn-1.patch
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:
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.
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.
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:
To test the results, issue: make test. Note that the Expect test suite is known to experience failures under certain host conditions that are not within our control. Therefore, test suite failures here are not surprising and are not considered critical.
Install the package:
make SCRIPTS="" install
The meaning of the make parameter:
This prevents installation of the supplementary Expect scripts, which are not needed.
