[opensuse-buildservice] How to solve libudev-devel:libudev-mini-devel conflict
In openSUSE:Factory:ARM the v4l-utils package has an unresolved dependency because v4l-utils requires udev for building which pulls in libudev1, but libgbm-devel depends on pkgconfig(udev) which resolves to libudev-mini-devel (we generally prefer that over libudev-devel) and pulls in libudev-mini1. How can the conflict between libudev1 and libudev-mini1 be solved? I tried adding "Prefer: libgbm-devel:libudev-devel", but that didn't change anything.

I think this is the correct solution: Conflict: libudev1:libudev-mini-devel This makes sure that libudev-mini-devel isn't considered if libudev1 is already selected.

You should probably wonder why v4l-utils really requires udev and not pkgconfig(udev)... Most likely this is just a work around for not having to own a directory where you install files to...

udev and pkgconfig(udev) are unrelated (neither depends on the other).

I would analyze it as follows: Since libudev-mini-devel requires libudev-mini1 which is marked as conflicting with libudev1 (hardrequired by udev by v4l-utils), the solver should abandon the libudev-mini-devel possibility for expansion of pkgconfig(udev) and never even get to a point where it has to consult Prefer lines. -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

The solver apparently doesn't look ahead. libudev-mini-devel doesn't conflict directly with libudev1, so it can still be selected to resolve pkgconfig(udev). The buildconfig of openSUSE:Factory contains "Conflict: libudev1:udev-mini" which probably was added to solve a similar conflict.
