Source: libcbor Version: 0.5.0+dfsg-2 Tags: patch User: [email protected] Usertags: cross-satisfiability
libcbor cannot be cross built from source, because its build depends are unsatisfiable. It also participates in dependency loops relevant to architecture bootstrap. Both are hard problems, so I rather looked into easily droppable dependencies and I have to say, that I'll not be leaving many. The first insight is that the libcbor documentation is nicely split into an arch:all package, but d/rules builds the documentation on arch-only builds as well. Indeed, the actual library build and the documentation build are fully separate. In this package, we can fully move the documentation build to -indep overrides and skip all library builds there. That allows partitioning all dependencies but debhelper to either B-D-A or B-D-I. While on it, I noticed that d/rules calls doxygen without depending on it. While the dependency is kinda implicit via python3-breathe, I think being explicit here would be better to avoid a late surprise. Finally, libcmocka-dev can be skipped via <!nocheck> as it is only used for testing. Since libcbor is normally reproducible, I went ahead and compared a full regular build without these changes to a full build, arch-only build and indep-only build with these changes (minus changelog) and they all matched exactly. Please consider applying the attached patch. Helmut
