Hi Stephan!
There are currently 27 different, per-platform C++ UNO bridge implementations at
bridges/source/cpp_uno/, some of which are presumably dead by now. And my recent

"Rudimentary support for dynamic_cast on UNO proxy objects" (which had to touch
each of them individually) was the latest example how even presumably dead ones
have ongoing maintenance cost. Therefore, I would like to remove (on master,
towards LO 7.6) the ones that can clearly be identified as being dead.
Below, I sorted those 27 implementations into 5 categories: Ideally, each active
implementation would be built regularly by Jenkins; those 9 that are go into category
1. Next, there are 2 additional implementations that I know are built for Fedora
releases; they go into category 2. Next, there are 2 additional implementations
that I presume are built for Debian releases (Rene, correct me if I'm wrong);
they go into category 3. And then there are 3 implementations that are presumably
in active use elsewhere (Tor, wjh-la, Sakura286, correct me if I'm wrong); which
go into category 4. That leaves 11 implementations that are presumably dead, in
category 5.
(5) Presumably dead:

* gcc3_solaris_intel
* gcc3_solaris_sparc
Oracle is still maintaining Solaris until at least 2035 and OpenIndiana is still maintained, too.
According to this article, LibreOffice 7.2.7 was shipped with OpenIndiana 2022.10:
https://www.theregister.com/2022/12/07/new_version_of_openindiana/
So, I'm not sure dropping Solaris support is a good idea either.
Thanks for that link.
From <https://en.wikipedia.org/wiki/OpenIndiana> it looks like at least OpenIndiana only supports x86-64, so neither gcc3_solar_intel (32-bit x86) nor gcc3_solaris_sparc (32-bit SPARC) should be relevant for it. I'm adding Andreas Wacknitz (who's the author of recent OpenIndiana announcements like <https://www.openindiana.org/2022/12/04/openindiana-hipster-2022-10-is-here/>) in CC, maybe he can shed some light on this. (Andreas, my full original email starting this thread is at <https://lists.freedesktop.org/archives/libreoffice/2023-January/089808.html> "Plan to remove dead C++ UNO bridge implementations (bridges/source/cpp_uno/*)").
I don't know if there are any other Solaris-based offerings for which current LO master gcc3_solaris_intel and/or gcc3_solar_sparc would still be relevant. If somebody knows of any, please report back here.
I'm adding two of the Solaris maintainers at Oracle that I know to ask them whether
the SPARC port for LibreOffice is still relevant for them.
