Re: Relicensing Nautilus to GPLv3+

[Carlos Soriano <csoriano protonmail com>]

Maybe I didn't explain well. Emilio points out there could one one of those extensions that say GPL2+ to link to a GPL2-only library. But that would make the extension itself GPL2 anyway, and it's License file would have to reflect that initially.

It's just a hipotetical case, I checked the extensions dependencies in a quick look and look fine (>= GPL+2).

No. nautilus' license says "GPLv2 or later". The extension's license

says "GPLv2 only".

When you combine both licenses into the final product/memory address

space (the "linking" mentioned in the GPL license) you end up with a

"combined work" license of GPLv2.

So it was compatible, but wouldn't be any more.

As mentioned on IRC, I think that the original intent of using the LGPL

for the libnautilus-extensions library was to allow non-GPL-compatible

extensions to link into nautilus, at will. It's not like you could link

to the extensions library without also eventually linking to nautilus

itself...

If that were the case, and that might require some digging to talk to

the original authors, then you might be able to mention this in the

extensions document that was recently (and erroneously) removed.
