Re: Bug#1114845: dh-builtusing: add support for virtual packages and improve support for cross-builds

[Nicolas Boulenguez <nicolas@debian.org>]

Hello.
Thank you for a such a detailed bug report.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1114845

I think the right fix is to skip a candidate when
 * the pattern mentions no explicit architecture (unchanged)
 * Architecture differs from host (unchanged)
 * Multi-Arch differs from 'same' (was: Architecture differs from 'all')

I have implemented this change in
https://salsa.debian.org/debian/dh-builtusing/-/commit/2a96171b2b724fb333ea61d291f7676fb2c20134
All tests pass, but they do not cover cross/multi-arch situations.

Could you please build dh-builtusing from 76af6011 and check if this
solves your issue?

By the way, I would welcome tests for cross/multi-arch situations,
including yours.
My first attempt (integration-tests/40multiarch{,-root}) is commented
in debian/tests/control because, two years ago (71f8f728), I have
failed to write a test that passes both in a local chroot and on
automated test runners (the log is not available anymore).
