Hello, this is a n00b question, but couldn't find any solution. I use Texstudio, and it has been working fine until recently. After a huge bunch of updates yesterday, Texstudio doesn't launch, and returns this error: *texstudio: error while loading shared libraries: libpoppler-qt4.so.3: cannot open shared object file: No such file or directory *My poppler-qt package is up to date. * *According to the AUR page, I shall rebuild Texstudio after my update of libpoppler-qt. I rebuilt the package, but when I want to install, I have a WARNING : Failed to install built package as a long list of usr/share/texstudio files exist in filesystem. My question is : how can I reinstall this AUR package? Shall I uninstall it before, and how? Shall I force the install, and how? Shall I just delete the already existing files in my filesystem? TY for your help.
