Dear maintainers,
In Ubuntu, we are in the process of moving the i386 architecture to a
compatibility-only layer on amd64, and therefore we are also moving our
autopkgtest infrastructure to test i386 binaries in a cross-environment.
This requires changes to some tests so that they are cross-aware and can do
the right thing.
The gdk-pixbuf tests currently fail in this environment, because they are
build tests that do not invoke the toolchain in a cross-aware manner. I've
verified that the attached patch lets the tests successfully build (and run)
i386 tests on an amd64 host.
Note that upstream autopkgtest doesn't currently set DEB_HOST_ARCH so this
is a complete no-op in Debian for the moment. Support for cross-testing in
autopkgtest is currently awaiting review at
https://salsa.debian.org/ci-team/autopkgtest/merge_requests/69 and once
landed, will still have no effect unless autopkgtest is invoked with a '-a'
option. So this change should be safe to land in your package despite this
not being upstream in autopkgtest.
Thanks for considering,
