Source: python-tornado Version: 6.5.2-3 Tags: patch User: [email protected] Usertags: cross-satisfiability
python-tornado cannot be cross built from source, because several of its Build-Depends cannot be satisfied. Before jumping into the problem, I note that some of them contain "sphinx" and that python-tornado neatly splits out an arch:all -doc package. Instead of looking at how to make them satisfiable, I suggest making them go away where away is Build-Depends-Indep. Once moving the dh --with arguments to declarative dh-sequence-* dependencies, we can just move all the sphinx dependencies to Build-Depends-Indep and have the sequence addon automatically skip the build step in override_dh_sphinxdoc. I'm attaching a patch for your convenience and used reproducible builds to verify that an arch-only build exactly reproduces the python3-tornado package from a full build. Helmut
