I've seen this happening before, like this or this.
My problem now is that I can't use goldendict from AUR. I just cannot rebuild it (I thought it would help after libicu update 72 -> 73). I'm getting this at the end of compilation:
linking goldendict
/usr/bin/ld: warning: libicuuc.so.72, needed by /usr/lib/libQt5WebKit.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libicui18n.so.72, needed by /usr/lib/libQt5WebKit.so, not found (try using -rpath or -rpath-link)
then go references like:
/usr/bin/ld: /usr/lib/libQt5WebKit.so: undefined reference to `u_toupper_72'
/usr/bin/ld: /usr/lib/libQt5WebKit.so: undefined reference to `u_foldCase_72'
/usr/bin/ld: /usr/lib/libQt5WebKit.so: undefined reference to `unum_getAvailable_72'
etc.
I know I can fix it with a dirty "ldconfig + libicu 72" trick, but why it is impossible to rebuild Goldendict?
Thank you in advance.
