I'm using PyInstaller to bundle a PySide2 application. In my application, I use QDesktopServices.openUrl (https://doc.qt.io/qt-5/qdesktopservices.html#openUrl) to open a PDF version of the user manual when the user clicks on the Help menu.
This works fine when I run the PySide2 application from terminal, whether it's on my Mac, Windows, or Ubuntu machines; it opens the manual in Preview, Microsoft Edge, and Evince, respectively. However, when I use PyInstaller to bundle the application via `pyinstaller MainWindow.py`, I get the following error on Ubuntu when I try to open the PDF: `evince: error while loading shared libraries: libgdk-3.so.0: failed to map segment from shared object` If I remove libgdk-3.so from the application bundle, I get the error: `evince: error while loading shared libraries: libpangocairo-1.0.so.0: failed to map segment from shared object` And this error continues with a different library if I then remove libpangocairo-1.0.so. I tried doing that through about 20 different libraries before I stopped trying to see when the issue would end. Evidently, this issue has been seen before. On https://answers.launchpad.net/kathaikalam/+question/206392, the program was explicitly calling Evince to open the PDF file, so the developer fixed the issue by calling xpdf instead. However, since QDesktopServices opens a local file using the operating system's default program, I can't tell it not to use Evince. So is there any way to get Evince to work with PyInstaller? Or any other workarounds? I thought about having my program determine if the OS is Ubuntu, and if so, not using QDesktopServices but instead explicitly use xpdf or some other program, but the issue there is that the user might not have that program installed. QDesktopServices is very nice in that it calls a program that's known to be present on the user's system. I'm using Ubuntu 20.04.2 LTS, PySide2 5.15.2, and PyInstaller 4.2.
