Hello,

Currently i have docbook2X not working on my system (a perl problem
that i don't know how to repair, but in a few months i will reinstall completely
this C:\Cygwin64 which dates back to 2019).

This means that /usr/share/docbook2X and /usr/bin/docbook2x-texi are missing.
Consequently, no *.info* file is produced.

Nevertheless, i tried to compile cygwin from sources (newlib-cygwin-3.3.6.tar.bz2),
knowing that "Normally, building ignores any errors in building the documentation"
(see https://cygwin.com/faq.html#faq.programming.building-cygwin)

However, in order to 'make' and then 'make install' properly, i had to apply the following
easy patch (below).

Hope this helps,

Regards,

Denis Excoffier.
