EDIT: Looks like this problem is with
qt5-base-nosystemd 5.8.0-2 (qt5-base works). Maybe it needs an update for the new
The unstable update today to
icu-59.1-1 and related packages broke smplayer (maybe other qt5 applications also, I didn’t test). And it was pretty difficult to downgrade.
First smplayer asked for libicui18n.so.58 and libicuuc.so.58, which I “provided” with symlinks, then it gave me “smplayer: symbol lookup error: /usr/lib/libQt5Core.so.5: undefined symbol: ucnv_getDefaultName_58” Maybe qt5 needs updating also?
But downgrading was difficult because apparently pacman needs icu libraries. I finally succeeded by downgrading
icu (which I had to use the so.58 symlinks for and then force). Then my file manager wouldn’t run until I also downgraded
EDIT: using the new
qt5-base 220.127.116.11 solves this.
