Good point. If you seriously consider that making binary packages first-class in your packaging system, (run-time) compatibility really matters. (Libh documentation doesn't refer to this at all, though.) > In a nutshell idea is to assign each port with something called > PKGABIVERSION (>=0, non-decreasing), which will need to be increased > each time when some ABI-incompatible change is committed (e.g. shlib > version bump) and make PKGREVISION of each port be an arithmetical sum > of PKGABIVERSION's of all its dependencies and its own PORTREVISION. > Actual implementation I'm leaving as an exercise for the reader, because > I do not use portupgrade by myself and therefore have no interest in > doing it on my own. For me `pkg_delete -r freetype2\* ; cd > /usr/ports/x11/gnome ; make reinstall' is absolutely sufficient. I think that versioning scheme need not be reinvented; SONAME versioning scheme may already do this in a better way. About SONAME, please refer to ABIcheck documents http://abicheck.sourceforge.net/ which impressed me much about a week ago. I wonder that it's not so hard to maintain a few *VERSION variables manually if you don't feel hard to maintain PORTREVISION manually. So what you need else is a policy and a good testing framework.
