Turns out you have to take care of dependencies/prerequisites yourself. It's a manual process that you have to take care of yourself; setup does not and cannot take care of this for you. You manually have to figure out what package version go together. However, I did find this website [2] that archives Cygwin packages releases by date, so that in essence you can go back to a specific date on which DD-MM-YYYY all packages were current in the past. I guess you could use that to go back to the ghostscript release you want. But this does mean that: [a] I'm guessing this is not a 'supported cygwin configuration' [b] You will downgrade to *all* other packages that were 'current' at that date. Not sure if this helps, and hoping someone else has a better answer, - Maarten [1] https://cygwin.com/pipermail/cygwin/2020-May/244772.html [2] http://www.crouchingtigerhiddenfruitbat.org/Cygwin/timemachine.html -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
