Use of GPLv3 within LibreOffice

Hello, I’m trying to understand the licensing of LibreOffice.

I noticed the main COPYING file in the core repo is GPLv3, and some of the files within this repo also have GPLv3/GPLv2+ license headers.

I couldn’t find any reference to these specific licenses as part of the licenses guidance, or talked about elsewhere.

I’m not very familiar with the codebase, or C-based codebases in general, to understand the use of this license and the applicable files, so unsure how their use relates to Libreoffice as a whole (and built/distributed project).

Would someone be able to confirm the use of the GPLv2+/GPLv3 in respect to the project as a whole?

Licenses | LibreOffice - Free and private office suite - Based on OpenOffice - Compatible with Microsoft

Thanks, but that page does not mention the use of GPLv3 at all, hence why I’ve asked here.

ah?

… jointly under both …

That part is about the LGPLv3, not the GPLv3. I understand the use of the LGPLv3, but I’m specifically interested in extra info in regard to GPLv3 usage here.

my understanding is that it is just a reference file, as are
COPYING.LGPL - core - Gitiles
and COPYING.MPL - core - Gitiles
or readlicense_oo/license/NOTICE - core - Gitiles

concerning the more restrictive aspects, I would rather refer to
Licensing and Legal information

and for historical purpose : Licensing FAQ

maybe @floeff can offer a definitive view on all this …
