Is librsvg really licensed under GPL?

[keven-ma]

librsvg v2.40 (https://github.com/GNOME/librsvg/tree/librsvg-2.40) contains two license files. One is GPL and the other is LGPL. According to https://gitlab.gnome.org/GNOME/librsvg/-/issues/72 and https://gitlab.gnome.org/GNOME/librsvg/-/issues/432. Federico Mena Quintero (the maintainer of librsvg) said the license should be LGPL. So can we change the [LICENSE] in (https://github.com/ImageMagick/VisualMagick/blob/main/rsvg/Config.txt) to librsvg\COPYING.LIB?

We can only use the LGPL license so that seems to be a mistake in the config.txt file from my side. I have updated the config file that you mention here. Thanks for pointing this out.

GPL is right.

https://github.com/ImageMagick/rsvg has two library librsvg (@v2.40.x) (https://github.com/ImageMagick/rsvg/tree/main/librsvg) and [gdk-pixbuf] (@v2.36.x) (https://github.com/ImageMagick/rsvg/tree/main/gdk-pixbuf).
librsvg is indeed LGPL. But gdk-pixbuf is GPL. gdk-pixbuf changed to LGPL at v2.37.0.
Once https://github.com/ImageMagick/rsvg/tree/main/gdk-pixbuf update to v2.37.0+ we can update the config file.

Everything I am reading says it is LGPL. Why do you think they use GPL in older versions?

[keven-ma]

I checked this file https://github.com/GNOME/gdk-pixbuf/blob/gdk-pixbuf-2-36/COPYING. It's GNU GPLv2.

This file (https://github.com/ImageMagick/rsvg/blob/main/gdk-pixbuf/COPYING) is also GNU GPL v2

[keven-ma]

The license is changed to LGPL in https://github.com/GNOME/gdk-pixbuf/blob/2.37.0/COPYING.
Can we update gdk-pixbuf to v2.37.0+? After that the whole rsvg project is LGPL.

Version 2.36.0 uses version 2.0 of the LGPL that used to be called GNU LIBRARY GENERAL PUBLIC LICENSE and version 2.37.0 uses version 2.1 of the LGPL that is now called GNU LESSER GENERAL PUBLIC LICENSE. So I don't think there is a need to upgrade the library.
