Makes sense. > I see three different solutions, which all suck in their own way: > a/ Make gir1.2-coglpango-1.0, gir1.2-cogl-1.0 and libcogl-pango0 break > libcogl5 This seems like the best choice of the three you mentioned. Anything using any of those and linking against libcogl5 will break, and "Breaks: libcogl5" seems like the best available proxy for "Breaks: everything depending on libcogl5 and this package". The more optimal but more difficult alternative: figure out all packages currently depending on libcogl5 and previous versions of the GNOME introspection bits, and declare a versioned breaks against all of them. > b/ Make libcogl9 break libcogl5 I don't think this one makes sense; those two libraries work fine on the same system as long as nothing loads both of them. > c/ Make libcogl9 break libclutter-1.0-0 << 1.10 I don't think this one makes sense either, though it comes closer. - Josh Triplett -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
