See fetch_source_files() in Sbuild/Build.pm. This is for installing and removing build-dependencies and build-conflicts, respectively. Note that dpkg-buildpackage and other tools read debian/control to check that the build-deps are satisfied in addition. > This difference of treatment between binary and source stanzas has > always puzzled me, but I'm not sure whether there is some deep > technical reason for that, or rather is just that the current buildd > implementations don't do that. I always thought that there was a rather simpler practical reason: substvars don't exist before a build starts, which is the point at which we need to install the build-deps. Regards, Roger -- .''`.
