libatspi2.0-dev is no longer muti-arch installable.
It now has a dependency on libgirepository1.0-dev, which isn't multi-arch.
2.50.0-1 didn't have that dependency

This breaks libgtk-3-dev multiarch install, since libgtk-3-dev depends on
libatspi2.0-dev via libatk-bridge2.0-dev.

Looking at the changelog, I don't see why the additional dependency is
necessary.
Even worse, for i386, this now pulls in ~250MB additional packages, because
libgirepository1.0-dev needs gobject-introspection:i386, which pulls in
gcc-i686-linux-gnu.

Hello,

Christian Klein, le sam. 02 mars 2024 16:33:15 +0100, a ecrit:

This is coming from gir:Depends:

./debian/libatspi2.0-dev.substvars:gir:Depends=gir1.2-atspi-2.0 (= 2.51.90-1), gir1.2-dbus-1.0-dev, gir1.2-gobject-2.0-dev, libgirepository1.0-dev

I don't know the ins and outs why this comes like this, thus asking for
help on this.

Control: clone -1 -2
Control: reassign -2 gobject-introspection 1.78.1-15
Control: retitle -2 dh_girepository: generates unwanted dependency on libgirepository1.0-dev if that package is installed
Control: severity -2 important

This was an unintended regression caused by changes made in
gobject-introspection, ironically to make multiarch co-installability and
cross-compilation of GObject-Introspection data possible. I am sorry to
have inconvenienced you and will try to fix the bug in dh_girepository
soon. I know that regressions are unacceptable, but this week there have
been several unrelated time-sensitive issues for which I have been made
a single point of failure, so I hope you will forgive me for not putting
this right at the top of my queue.

The bug is that if libgirepository1.0-dev is installed, dh_girepository
will wrongly generate dependencies on that package in preference to
gir1.2-glib-2.0-dev. This is because, for backwards compatibility
with packages that have not yet been updated to look for GIR XML
in a multiarch-friendly location, libgirepository1.0-dev provides a
symbolic link to the architecture-specific GIR XML for GLib-2.0 in a
non-multiarch-friendly location. This backwards compatibility glue is also
the reason why libgirepository1.0-dev cannot be Multi-Arch: same.

Samuel or other AT-SPI maintainers, if you want to avoid this unwanted
dependency while also bringing libatspi2.0-dev one step closer to being
cross-compilable itself, please consider replacing the build-dependency on
libgirepository1.0-dev with the canonicalized package names corresponding
to the GIR modules required by the upstream source, which according to
the build log means this:

(Compile-tested only, I have not attempted to verify that the resulting
binaries are perfect; at the moment I'm only looking at this while I wait
for an urgent glib2.0 bug fix to finish running automated tests, and I
will have to re-prioritize back to glib2.0 as soon as it is ready. I
apologise for not providing an exhaustively-tested, production-ready
solution right now.)

Heh :)

No problem, thanks for the quick feedback!

Oh, indeed. This does look right and produces correct binaries, I'll
upload that, thanks!
