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

"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_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.
