[Pkg-ayatana-devel] Bug#1123683: libunity FTCBFS: multiple reasons

[Helmut Grohne]

Source: libunity
Version: 7.1.4+19.04.20190319-6.1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability ftcbfs

libunity fails to cross build from source for two distinct reasons.

It Build-Depends on a host architecture python3 and python3-gi. Those
packages cannot be installed for the host architecture as the Python
interpreter would fail its postinst attempting byte compilation. The gi
module is used by configure.ac to discover an architecture-independent
override directory. Hence using the build architecture one is ok.

It also has a separate build pass for Python during
override_dh_auto_install. That step fails to pass --host to configure.
The easiest way to fix that is using dh_auto_configure.

I'm attaching a patch combining the necessary changes. Please consider
applying it as doing so makes libunity cross buildable.
