I believe the problem arises when you (build-)depend on libprotobuf-c0-dev, without protobuf-c-compiler. That happened with riemann-c-client: * I changed the build-dependency to libprotobuf-c-dev | libprotobuf-c0-dev + protobuf-c-compiler. * On unstable, that correctly pulled in libprotobuf-c-dev * Headers were generated using the new protobuf-c-compiler * The libriemann-client-dev package still had a dependency on libprotobuf-c0-dev, though. * syslog-ng-incubator build-depends on libriemann-client-dev, which pulled in libprotobuf-c0-dev and libprotobuf-c1! * syslog-ng-incubator FTBFS'd because of the generated header conflicted. I ended up changing the libriemann-client-dev dependency to libprotobuf-c-dev, and all is well. So another thing to pay attention to is transitive build-dependency, as that can - and will - break if one's not forcing libprotobuf-c-dev onto the system. > I think all of the packages I listed in my original email had a > build-dep on either protobuf-c-compiler only, or protobuf-c-compiler and > libprotobuf-c0-dev. (I don't think there are any with just > libprotobuf-c0-dev.) Not directly, but transitively, syslog-ng-incubator build-depends on libriemann-client-dev, which depended on libprotobuf-c0-dev only, without protobuf-c-compiler. I'm not sure if there are other packages like this, but the riemann-c-client + syslog-ng-incubator combo has been taken care of. -- |8] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
