Also a fair number of warnings about deprecated functions when built with -Wdeprecated-declarations .

Thank you for your report. Unfortunately, I can't reproduce your problem. Also, it seems to me that other sources than mine were used in the linked bug report, so it's of little use to me. If you believe, the problem there also applies to this repository, please create a fresh clone of this repository and provide the full console output of all your compilation steps. Please also tell me your compiler versions. Thank you.

This repo is indeed affected when trying to build against cups 2.3.0. cups/sidechannel.h must be added explicility to CupsPrintEnvironment.cpp.

There are also numerous warnings about ppdClose deprecation and similar. For now that is not breaking build
