EDIT: If found and installed libidn11 in the repos and then rainlendar started without error, but the GUI was not rendered normally, so I had to uninstall rainlendar.
Since ICU-63, errors while loading shared libraries: libicui18n.so.62 etc.
Solved by upgrading webkitgtk2 to version 3:2.4.11-14, which is rebuilt against the new ICU-63.
EDIT Alternatively, an AUR package of 'icu62 62.1-1' was released on 2018-11-05.
pacman now recommends avoiding webkitgtk2 because of security issues and moved it to AUR. Can it be replaced?
Rainy (of rainlendar) said in July 2017: "I don't know why the library is marked as unsafe. It's used for the OAuth e.g. in Google Calendar so Rainlendar doesn't work without it."
libjpeg6 is not available in aur anymore.
Rainlendar doesn't work after I updated both of my computers?
Rainlendar-lite stopped working after I did a recent update of the system. I'm a bit baffled as to what to do.
Could the cause be connected with "libjpeg6-turbo-1.3.0-1".
Either way before or after my intervention Rainlendar will not work.
