Hi Victor,

Thanks for sharing the document.

I have a query on the document while I follow the steps which are given in the document, I am stuck at a step 2 which is given in section 3.5.2(Compile Cryptsetup). It looks like the command is incomplete and because of that I am getting the following error.

Can you please guide me for the same?

It seems your system lacks of popt (that provides libpopt libraries to parse command-line options).
So you need to install this package.
