I added an issue upstream https://github.com/jwilk/pdf2djvu/issues/149

Thanks! That would be helpful.

@frankspace No, I am not really familiar with using chroot to test packages. I do not have either packages you mentioned installed in my system, but please let me know if sending to your email address the list of my installed packages may help you narrow down the possible cause of the issue

Interesting. Are you compiling it in a chroot? I'm trying to figure this out, and I have a suspicion that it may have something to do with the upstream author inexplicably refusing to port the tests to python3 and refusing to explain why. Do you by any chance happen to have an old version of python2-exiv2 installed? Or possibly python2-xmp-toolkit? It's just the tests that are failing; when I comment out the check() section, this compiles (and seems to work) just fine.

@frankspace Unfortunately I cannot replicate the error, it compiles correctly on my machine.

Compilation fails for me, even in a clean chroot:

This is fixed in git master https://github.com/jwilk/pdf2djvu/commit/e528d3ab88c582e8481c9014982263d9c9e992fe, but the author doesn't seem to have made a release yet.

UPDATE; the AUR bug has been fixed, and I have regularly updated the package

Thank you @jsh6789 for pointing that out, I have reported it to the dev, and he has released a new version of the programme.
I am currently waiting for this AUR bug to be fixed so I can go ahead and push the update.
For those who need the package more urgently, I suggest to compile manually the latest release.

Patch is needed to compile successfully with GCC11:
