Install Expect on Ubuntu 16.04

I've just tried this on a 16.04, but it should work on older versions of Ubuntu as well.

(1) Download and install ActiveTcl Free Community Edition

http://www.activestate.com/activetcl/downloads

Download and extract the files, then cd into the extracted directory and run ./install.sh (with root permissions).

Follow the installation instructions and put everything under the default directory (/opt).

(2) Download Expect

https://sourceforge.net/projects/expect/files/Expect/

Extract the contents into /opt.

(3) Configure, build, install Expect

From the installation directory (example /opt/expect5.45/), run the following commands:

$ sudo ./configure \
--with-tcl=/opt/ActiveTcl-8.6/lib/tcl8.6 \
--with-tclinclude=/opt/ActiveTcl-8.6/include/tcl8.6 \
--with-tk=/opt/ActiveTcl-8.6/lib/tcl8.6 \
--with-tkinclude=/opt/ActiveTcl-8.6/include/tcl8.6
$ sudo make && sudo make install

To have the final executable globally available, create a symlink for it:

$ sudo ln -s /opt/expect5.45/expect /usr/bin/expect

On ubuntu 16 I tried to install, but the error it gave was:

checking for correct TEA configuration... ok (TEA 3.9)
configure: configuring expect 5.45.4
checking for Tcl configuration... configure: error: /opt/ActiveTcl-8.6/lib/tcl8.6/ directory doesn't contain tclConfig.sh

I edited this to run and was able to proceed with the install.

sudo ./configure \
--with-tcl=/opt/ActiveTcl-8.6/lib \
--with-tclinclude=/opt/ActiveTcl-8.6/include \
--with-tk=/opt/ActiveTcl-8.6/lib/tcl8.6 \
--with-tkinclude=/opt/ActiveTcl-8.6/include/tcl8.6
