Hi,
(I hope this is the right place to ask...)
I'm on Arch Linux and just wanted to get acquainted to (early) gtkmm4.
Unfortunately, there are no pre-release packages (like 3.97.1) in AUR
yet. I might be able to build them, but some of the dependencies
mentionend by [1] seem not to be released yet (pangomm-2.44,
cairomm-1.16, atkmm-2.30). Perhaps it would be necessary to build them
from git master, but I think I read something about ABI
incompatibility, which would make it even more complicated.
So, is it just too early to give gtkmm4 a try? If not, I would be glad
to have something like a guide about how to get started.
(btw, a gtkmm matrix room would be great. The closest thing I found is
a #c++ irc channel on GIMPnet. Maybe I missed something?)
Thanks a lot
Martin

Building gtkmm4 from released packages is almost impossible, and
certainly not recommended. If you want to give it a try, build from git.
I recommend that you use jhbuild. And be prepared for compilation errors
when you come to gtkmm4. Gtk4 is constantly changing. Only rarely is
gtkmm4 totally compatible with gtk4. See also
https://mail.gnome.org/archives/gtkmm-list/2020-January/msg00009.html.
(The lists of latest released versions there are not quite up to date.)
Is it too early to give gtkmm4 a try? Probably, unless you can accept
more build problems than usual. You can have a look at the example
programs in the gtkmm-documentation module in git's master branch. They
can give some hints as to the differences between gtkmm3 and gtkmm4.
