Poppler issues

[karlicoss]

Ubuntu 20.04. I tried on a fresh virtualbox install to avoid messing with qt libraries installed in the main system.

Followed the instructions in readme:

• don't have brew in ubuntu, but I've ran apt install cmake libpoppler-qt5-1, and also apt build-dep cmake libpoppler-qt5-1 -- just in case some build dependencies are also necessary
• successfully ran both pip commands
• when trying to open a PDF in the app, I get

Traceback (most recent call last):
  File "/shared/remy/remy/gui/filebrowser.py", line 442, in openEntry
    self.viewers[uid] = NotebookViewer(index.get(uid))
  File "/shared/remy/remy/gui/notebookview.py", line 99, in __init__
    self._maxPage = document.baseDocument().numPages() - 1
  File "/shared/remy/remy/remarkable/metadata.py", line 256, in baseDocument
    from popplerqt5 import Poppler
ImportError: /home/dev/.local/lib/python3.8/site-packages/PyQt5/QtXml.abi3.so: undefined symbol: _ZN12QDomDocument10setContentEP16QXmlStreamReaderbP7QStringPiS4_, version Qt_5

Seems like a mismatch between python API and the installed library.

I also tried installing via brew, but even though it installed successfully, it still couldn't find the poppler library, unless I installed it via apt.

And the final option I tried -- running pip3 uninstall pyqt5 pyqt5-sip python-poppler-qt5 and then installing them via the package manager (generally this would mean more consistent versions): apt install python3-poppler-qt5 python3-pyq. Then when opening a pdf I'm getting

Traceback (most recent call last):
  File "/shared/remy/remy/gui/filebrowser.py", line 442, in openEntry
    self.viewers[uid] = NotebookViewer(index.get(uid))
  File "/shared/remy/remy/gui/notebookview.py", line 99, in __init__
    self._maxPage = document.baseDocument().numPages() - 1
  File "/shared/remy/remy/remarkable/metadata.py", line 262, in baseDocument
    self._pdf.setRenderHint(Poppler.Document.HideAnnotations)
AttributeError: type object 'Document' has no attribute 'HideAnnotations

not sure if it's much better though, presumably this method was added in a more recent poppler version, and that's why you were suggesting to install from github in the first place?

Any luck? I don't have a Linux machine at hand to try...python-poppler-qt5 is both very convenient to use and super annoying to install...I wish there was a good alternative...

This worked for me on Ubuntu 20.04: frescobaldi/python-poppler-qt5#41 (comment)

The new version on the devel branch can replace python-poppler-qt5 with the much easier to install PyMuPDF.
You can try and see if that makes it work for you.
