libpeas-2 comes with API and ABI changes and and removal of the GTK interfaces.

[raveit65]

From libpeas migration guide https://gitlab.gnome.org/GNOME/libpeas/-/commit

Peas 2 is a major new version of Peas that breaks both API and ABI compared to
Peas 1.0. Changes to the API, such as removal of the GTK interfaces and
adoption of `GListModel`, make it easier to adapt to broader changes in the
platform and modern UX patterns.

After migrating to Peas 2, applications can take advantage of the
[new list widgets][gtk4-listwidgets] if using GTK4, or continue using GTK 3
with the existing widgets like [`Gtk.ListBox`][gtk3-listbox].

Expected behaviour

A working plugin system with libpeas-2.0.0

Actual behaviour

Steps to reproduce the behaviour

Buildig against libpeas-2.0.0

MATE general version

1.26 and 1.27

Package version

1.26 and 1.27

Linux Distribution

Stable fedora 39 comes with 2 versions of libpeas.
libpeas-1.36.0-2.fc39
and
libpeas-2.0.0-3.fc40
Building with libpeas2 is broken

Link to bugreport of your Distribution (requirement)

I am sure people will file some rhbz reports the next weeks.

My first reaction is that Fedora is kind of pushy by not providing 1.0 whereas 2.0 seems to have been released for only 2 months… but well.
IIUC if we want to support 2.0, we'll have to re-do (possibly copy over) all the interface code, and adjust for the differences. This might not be a trivial task though.

[cwendling]

Actually, seems like you could just update the dependency to libpeas1-devel, at least for now.

[raveit65]

Ahh, i didn't saw that early in the morning that my distro ships 2 version for f39
libpeas-1.36.0-2.fc39
and
libpeas-2.0.0-3.fc40

I was also wondering that libpeas-2 was used for f39 stable.....i need to drink more coffee :-)
Ok, i will update CI.

Are libpeas-1 and libpeas-2 coinstallable? Note that "modern UX patterns" is what we are NOT using for the most part
