SUMMARY When a local PDF is attached to a Bibtex entry (via "localfile"), I can't open it in KBibTex's UI. STEPS TO REPRODUCE 1. Create a new Bibtex file with an arbitrary entry, go to the entry's "External" tab ("Extern" in German). 2. Attach a local PDF and a website link there. OBSERVED RESULT When clicking the "Open" button in that "External" tab for each entry, the webpage opens in the default browser, but the PDF button does nothing. When saving the entry, right-clicking it and selecting "View document" ("Dokument betrachten" in German), clicking the webpage entry opens it in the default browser, while clicking the PDF entry does nothing. There is no output in the console when starting KBibTeX there. EXPECTED RESULT The PDF should open in the default PDF viewer in both cases.

It is possible that your bug report is a duplicate of bug 459150. Can you please test if the fix commit to branch kbibtex/0.9 fixed you problem and/or if the bug still exists in branch kbibtex/0.10 which will become the future KBibTeX 0.10? For instructions, please see comment 1 for bug bug 459150: https://bugs.kde.org/show_bug.cgi?id=459150#c1
A workaround I just discovered: Opening the PDF with the keyboard shortcut (Ctrl+D) works fine. Using your instructions in the linked issue, I could verify that it does still not work in the 0.9 git version. When trying to run the 0.10 git version, I got this build error: -- The following OPTIONAL packages have not been found: * Qt5NetworkAuth * Qt5WebEngineWidgets * Qt5WebKitWidgets * Qt5 (required version >= 5.9.0) -- Configuring done CMake Error at src/networking/CMakeLists.txt:59 (add_library): Target "kbibtexnetworking" links to target "Qt5::NetworkAuth" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? Installing libqt5networkauth5-dev fixed the issue, so it seems to be a misclassification as "optional dependency". Compiling the 0.10 git version works, but it fails to start due to the following error: /tmp/flo-kbibtex-usr/bin/kbibtex: error while loading shared libraries: libkbibtexprocessing.so.0: cannot open shared object file: No such file or directory

Please try this here: bash run-kbibtex.sh 'https://invent.kde.org/thomasfischer/kbibtex.git' 'bugs/kde459911' > When trying to run the 0.10 git version, I got this build error: > [..] > /tmp/flo-kbibtex-usr/bin/kbibtex: error while loading shared libraries: > libkbibtexprocessing.so.0: cannot open shared object file: No such file or > directory You cannot simply compile the code and run the resoluting kbibtex binary. There are some shared libraries such as libkbibtexprocessing which are not found then as they lurk somewhere in the build directory. Please use the run-kbibtex.sh script which will setup a temporary installation inside /tmp without interfering with your regular installation and without using su or sudo.
(In reply to Thomas Fischer from comment #3) > You cannot simply compile the code and run the resoluting kbibtex binary. I did. The last line of the output from "bash run-kbibtex.sh 'https://invent.kde.org/thomasfischer/kbibtex.git' 'kbibtex/0.10'" is exactly the mentioned error. > Please try this here: > bash run-kbibtex.sh 'https://invent.kde.org/thomasfischer/kbibtex.git' 'bugs/kde459911' Clicking the button in the "External" tab next to a PDF entry now opens Okular like expected. So one bug fixed :) In the list, Ctrl+D still works as expected, but "View document" in the context menu still does only work for online entries, not for local PDF files.
To clarify: "I did" from my previous comment refers to your last sentence "Please use the run-kbibtex.sh script".
> In the list, Ctrl+D still works as expected, but "View document" in the > context menu still does only work for online entries, not for local PDF > files. Are you using localfile="abc.pdf" or something else? Can you please provide a minimal BibTeX file that reproducible does not work with KBibTeX?
Created attachment 152794 [details] Minimal reproduction I am using curly braces, not quotes. But the file path is relative like in your example: > localfile = {wu2019compression.pdf}
(In reply to Florian Edelmann from comment #7) > Created attachment 152794 [details] > Minimal reproduction I tested the file by placing another PDF file named "wu2019compression.pdf" next to it. The PDF file can be opened in the main view both via Ctrl+D and the context menu ("View Document" -> "Local files") as well as when opening the editing dialog, switching to tab "External" and opening the file using the button next to the filename's entry. I suspect that there is another problem on your machine, causing problems here. Opening a PDF file is, for KBibTeX, a simple operation asking the desktop environment to open a file with the associated tool (e.g. Okular). KBibTeX does not receive any feedback whether this succeeded or not. To mimic KBibTeX's opening request, using a terminal in KDE, navigate to the directory where "wu2019compression.pdf" is located. Then, issue these commands: xdg-open wu2019compression.pdf kde-open wu2019compression.pdf kde-open5 wu2019compression.pdf I am not sure which will be available, may depend on your distribution and package selection. Please report back what happens (output in terminal, error message, success?).
(In reply to Thomas Fischer from comment #8) > xdg-open wu2019compression.pdf > kde-open wu2019compression.pdf > kde-open5 wu2019compression.pdf All three commands successfully open the PDF in Okular. There is a warning in the terminal "Unable to open QuickAnnotatingTools XML definition" but that seems to come from Okular itself and doesn't have a negative consequence.

Although that is good for you, it does not help me in locating the problem. I added some debug output near the opening of the PDF document to the bug's Git branch. Maybe that gives some useful data. Please run the previous 'run-kbibtex.sh' command with 'bugs/kde459911' at the end. Verify that the script's output states that you run commit 58c75501646fc2024b6f63 as well as that when you try to open a PDF document, there is a debug output similar to: [info] kbibtex (/path/to/kbibtex/src/parts/part.cpp:903) - About to open URL "file:///path/to/wu2019compression.pdf"
Thanks for investigating! I've executed the script like you requested: > bash run-kbibtex.sh 'https://invent.kde.org/thomasfischer/kbibtex.git' 'bugs/kde459911' Its output includes the following line on startup: > [info] kbibtex (/tmp/flo-kbibtex-git-a3da32a0acdc0a4ba86f7b93436ea11c/src/program/program.cpp:63) - Starting KBibTeX version "58c75501 (bugs/kde459911)" When pressing Ctrl+D for one of the entries, Okular opens correctly. But there is no special output, just the same Okular warning as before: > [warning] okular (unknown:0) - Unable to open QuickAnnotatingTools XML definition When clicking the button in the edit dialog's "External" tab, Okular opens correctly and there is this console output: > [info] kbibtex (/tmp/flo-kbibtex-git-a3da32a0acdc0a4ba86f7b93436ea11c/src/gui/field/fieldlineedit.cpp:356) - About to open URL "file:///home/flo/www/master-thesis/master-thesis/papers/wu2019compression.pdf" with MIME type "application/pdf" > [info] kbibtex (/tmp/flo-kbibtex-git-a3da32a0acdc0a4ba86f7b93436ea11c/src/gui/field/fieldlineedit.cpp:363) - KRun::runURL returned true > [warning] okular (unknown:0) - Unable to open QuickAnnotatingTools XML definition When trying to open the PDF via the context menu, nothing happens at all. No Okular opening, no console output. For reference: Clicking an "external" URL via the context menu opens Firefox with that URL correctly.
