How To Fix ctanglex: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu ctanglex is provided by cwebx package.

cwebx is:

CWEBx is a complete rewrite of Levy & Knuth’s version of CWEB. It uses a slightly different syntax from the L&K version, but provides a compatibility mode allowing L&K CWEB sources to be processed, producing similar (though not necessarily identical) output.

CWEB allows you to write documents which can be used simultaneously as C/C++ programs and as TeX documentation for them.

The philosophy behind CWEB is that programmers who want to provide the best possible documentation for their programs need two things simultaneously: a language like TeX for formatting, and a language like C for programming. Neither type of language can provide the best documentation by itself. But when both are appropriately combined, we obtain a system that is much more useful than either language separately.

To fix this problem, we can install more using the command below.

sudo apt-get -y install cwebx

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install cwebx.

sudo apt -y install cwebx

Or if you have aptitude installed you can use the following command.

sudo aptitude install cwebx
