New comment by l4s8g on void-packages repository https://github.com/void-linux/void-packages/issues/5602#issuecomment-573605841 Comment: I'm sorry, i guess i wasn't clear in my last comment, i got zathura working with forward and backward search now., after changing the permissions of the files. These permission problems are really bugging me though and i haven't experienced anything like this before. That's why i asked if others also experience permission issues. > Is it libsynctex.pc or just plain synctex.pc? It's the latter for me.. -> synctex.pc > All of my /usr/lib/*.pc files have 644 permissions, so are universally readable. I have to set 644 permissions myself for new .pc files. Also for new folders.
