I found what the problem was: kdesupport was happily not building
phonon for some unknown reason, so knotify4 was linking to previously
and old installed libphonon, which was triggering binary-compatibility
link errors. I don't know yet why phonon was disabled in my build: I
thought it would be because of an unmet dependency, but I executed
cmakekde in kdesupport/phonon and it compiled and installed just fine
(and I suppose setting with cmake-gui BUILD_PHONON to 1 and executing
make install in kdesupport/ dir would do the same). As I have
experienced, phonon is required for kdebase, so I suppose phonon
should be REQUIRED for kdesupport compilation to succeed, which
doesn't seem to be happening.. or I might be missing something. Any
insight?
