User: [email protected]
Usertags: cross-satisfiability ftcbfs
zxing-cpp fails to cross build from source for two reasons both of which
relate to its Python extension. The python3-dev build dependency cannot
be installed for the host architecture as the host architecture Python
compiler fails postinst when attempting byte compilation. Instead a
build architecture interpreter and a host architecture development
package is needed. This is usually achieved by depending on
python3-dev:native and libpython3-dev. Beyond this, the extension build
defaults to using the build architecture name for installing the built
extension. It needs to be told about the correct path via the sysconfig
mechanism. I'm attaching a patch addressing both problems. Please
consider applying it as it makes zxing-cpp cross buildable.

* debian/control: Bump Standards-Version to 4.7.3.
* debian/tests/control: Manually write python-based autopkgtest
instead of relying on autodep8 for autopkgtest generation since
this package is only built against the default python3 version,
not all supported python3 version.
* debian/tests/autopkgtest-pkg-python.conf: Deleted accordingly.
