I am trying to install a tool that makes of use of a version of pdfparser from some years ago. The developer has advised me to install the newest version and adapt it accordingly. I have compiled the newest poppler library, 22.10.0, (with some difficulty) and followed the steps in build_poppler.sh, with the exception that I didn't clone from the specific named version of poppler (0.62.0), then followed by cmake and make, copying the relevant .so files, and then running python setup.py install.
It would seem that the expected file structure for poppler has changed since pdfparser's latest release, so I had to edit many header files. This now seems to be fixed, but there are some warnings and errors based on the code, and so I would like to know if a relatively quick fix is possible, or perhaps you know whether some forks address this, or whether I have to give up on this for now. I'm listing the output. I'm working on Pop!_OS 22.04 LTS, which is Ubuntu based. Thanks for your consideration.
