Install Expect on Ubuntu 16.04

install-expect-on-ubuntu.md

http://expect.sourceforge.net/

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

You need a c compiler in your system. I used gcc (apt-get install gcc if you don't have it previously)
Actually there are some mistakes in the ./configure command as some paths don't exist.
This is what I run (I picked /usr as base folder instead of /opt):
./configure --with-tcl=/usr/ActiveTcl-8.6/lib --with-tclinclude=/usr/ActiveTcl-8.6/include --with-tk=/usr/ActiveTcl-8.6/lib/tcl8.6 --with-tkinclude=/var/ActiveTcl-8.6/include
ActiveTcl-8.6/include folder doesn't have a tcl8.6 sub-folder
And in --with-tcl you have to provide the path to tclConfig.sh which is ActiveTcl-8.6/lib not ActiveTcl-8.6/lib/tcl8.6
Apart from this everything runs smoothly.
Thanks a lot

I'm stuck at private-headers.
Below is what I get when I run ./configure :

• The file tclInt.h is available in the /opt/ActiveTcl-8.6/include/ Directory .
• I created a Symbolic link "incl" and pasted it in opt/expect5.45.4/
• I edited the "tclConfig.sh" file, parameter "TCL_SRC_DIR" in line 149 (which had the previous [non-existent]DirectoryPath, prior to "opt/expect5.45.4/" )

Please help me understand how the filepath is being read?
If Possible, the solution to this issue .

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
