You're forgetting the other cases where files have to be found, which are not "a lib finding its own files". In many many cases (other than libexec), the files have to be found "externally". The icon loader code needs to find the icons. The mimetype code has to find the mimetype definitions. kconf_update has to find update files. Workspace autostart has to find autostart files. etc. etc. XDG_DATA_DIRS does this. Magic determination of a lib's own prefix inside that lib's code doesn't. But yes, if you install libkarchive, you don't need any of this. It's just code, no data files and no external processes, so your "plug and play" wish is granted, it's just like any other "pure library". The commercial developer can just put karchive.dll next to QtCore.dll (and IIRC, if that's in the same dir as the .exe, no $PATH needed). However when you install KIO, helper binaries have to be found, config files have to be found, icons have to be found, plugins have to be found (kioslaves), etc. The current solution (QStandardPaths) is to either install that into standard directories (/usr or /usr/local on Unix, "Application Data" on Windows), or to set additional XDG env vars (on Unix), for custom prefixes. If you have a specific idea on how to improve that I'm listening, but "it should work out of the box" is just a wish. I guess QStandardPaths could also look in the application directory, on Windows, to help with the "everything in the same directory" case. But on Unix, using the lib's own dir and then "going up" seems very very fragile and non-standard to me. I don't see the full solution you have in mind there. -- David Faure, fa...@kde.org, http://www.davidfaure.fr Sponsored by BlueSystems and KDAB to work on KDE Frameworks _______________________________________________ Kde-frameworks-devel mailing list Kde-frameworks-devel@kde.org https://mail.kde.org/mailman/listinfo/kde-frameworks-devel
