Version: 4.1.1-1
Tags: patch
User: [email protected]
Usertags: cross-satisfiability
The python3-sphinx dependency poses an issue to cross building mpi4py as
it cannot be satisfied. Fortunately, mpi4py already disables its
documentation build during arch-only builds, so the use left is the
sphinxdoc debhelper addon. Once turning it declarative (Build-Depends:
dh-sequence-sphinxdoc), it can also be moved to Build-Depends-Indep and
then python3-sphinx can also be moved there. Thus the unsatisfiable
dependency has become irrelevant. I'm attaching a patch for your
convenience. Using reproducible builds, I verified that it does not
affect output artifacts.
