(In reply to Dr. Werner Fink from comment #16) > I really wonder why both qpdf and cups-filters at build time do not depend > on the version of libgs/ghostscript within the spec files. qpdf is on my list for a BuildRequires of cups-filters-1.25: BuildRequires: qpdf-devel >= 8.3.0 So it is not a runtime requirement but a build requirement. Anyway, when I install cups-filters-1.25, then also libqpdf.so.26 is required at runtime.
