Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build:

Hello Santiago,

nlohmann-json3-dev has a well-known upstream bug that causes it to breaks the ABI with each minor version, see for example:

xeus (3.1.3-2) unstable; urgency=medium

* d/control: build-depend on nlohmann-json3-dev 3.11.3
The API of this library exposes types from nlohmann::json, and this
resulted in an ABI change depending on whether libxeus and the kernel
are built against 3.11.2 or 3.11.3. This adds an explicit dependency
on nlohmann-json3-dev 3.11.3. This explicitly chooses the newer version
for libxeus and dependencies. (Closes: #1060164, #1061007)

Unfortunately Gianfranco uploaded a new minor version of nlohmann-json3-dev during the
freeze, hence breaking unstable. I suppose the other xeus packages have the same bug.

%rmadison nlohmann-json3-dev
nlohmann-json3-dev | 3.5.0-0.1 | oldoldstable | all nlohmann-json3-dev | 3.7.0-2~bpo10+1 | buster-backports | all nlohmann-json3-dev | 3.9.1-1 | oldstable | all nlohmann-json3-dev | 3.11.2-2 | stable | all nlohmann-json3-dev | 3.11.3-2.1 | testing | all nlohmann-json3-dev | 3.12.0-1 | unstable | all

So I am unsure what to do. How are we supposed to deal with RC bug in unstable that do not affect stable ?

Cheers,

I am also unsure about what to do. Gianfranco, can you please comment on this?

Note that the three bugs against xeus-* which I reported today are the only ones
of this type which I found after building all packages in unstable, so adapting to the new nlohmann would not be a very bad option.

[ But someone should probably talk with Release Managers and explain this,
as I am just a bug reporter... ]

Thanks.

The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

Thanks!
I would really like to see the buildlog for xeus itself, if you have it.
