Package: libhtml-tagset-perl Version: 3.20-3 Tags: patch User: [email protected] Usertags: cross-satisfiability Control: affects -1 + src:cod-tools src:feersum src:gfxboot src:gnuift src:libapache2-mod-perl2 src:libdevel-cover-perl src:libebook-tools-perl src:libhtml-parser-perl src:libhtml-strip-perl src:libmarpa-r2-perl src:mimedefang src:netsurf src:os-autoinst src:spamassassin
The affected packages fail to satisfy their cross build dependencies, because their (transitive) dependency on libhtml-tagset-perl is unsatisfiable. In general, Architecture: all packages can never satisfy cross Build-Depends unless marked Multi-Arch: foreign or annotated :native. In this case, I'm arguing that Multi-Arch: foreign is reasonable. libhtml-tagset-perl is a pure perl module. It runs on any perl interpreter (embedded or standalone). It is not flagged by the multiarch hinter due to its perl dependency. In principle, it would make sense to annotate that dependency with :any, but doing so is practically irrelevant at present and difficult to do. The dependency is added by dh_perl (I guess) and adding the annotation would mean changing dh_perl. It is practically irrelevant, because changing the architecture of perl-base is very difficult as it is essential. Still the interfaces that libhtml-tagset-perl provides can be described as architecture-independent if some perl is assumed. Please consider applying the attached patch. I think that in general, many pure perl modules that entirely lack dependencies beyond perl can be thus annotated. Those that do have dependencies are more difficult and should be evaluated on a case-by-base basis taking into account whether doing so actually provides any practical benefit. Here, I've documented the practical benefit. Helmut
