[Digikam-devel] Compiling DigiKam: conflicting return type specified for virtual void Digikam::KipiInterface::preview(const QUrl&, int)

[Gilles Caulier]

your libkipi is outdated. You need current git/master code from libkipi to
compile current digiKam until final digiKam release. libikipi API is not
yet fully stabilized, and library is not yet released officially.
