[DSE-Dev] Bug#1022967: libsemanage FTCBFS: python and ruby extensions

[Helmut Grohne]

Source: libsemanage
Version: 3.4-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability ftcbfs

libsemanage is long part of architecture cross bootstrap, but a full
cross build of libsemanage without build profiles still doesn't work
yet.  Given the recent work on ruby by Antonio Terceiro (thanks!), it is
now possible to fix that. I'm attaching a patch that solves all of the
involved problems and makes libmanage cross buildable.

1. Multiarchify python build depends.
2. (optional cleanup) Use declarative debhelper addons.
3. export _PYTHON_SYSCONFIGDATA_NAME
4. export RUBYLIB
