Re: [Tuxpaint-devel] Doesn't compile on Rocky9

[Mark K. <mar...@gm...>]

I'm getting a warning on Ubuntu 20.04.1 LTS about the use of a deprecated
function "rsvg_handle_close".  Ubuntu 20.04.1 LTS  comes with librsvg
2.48.9.
The warning occurs several times while compiling tuxpaint.c but here is one
example:

src/tuxpaint.c:21011:5: warning: ‘rsvg_handle_close’ is deprecated: Use
'rsvg_handle_read_stream_sync' instead [-Wdeprecated-declarations]
21011 |     rsvg_handle_close(rsvg_handle, &gerr);
      |     ^~~~~~~~~~~~~~~~~
In file included from src/tuxpaint.c:516:
/usr/include/librsvg-2.0/librsvg/rsvg.h:192:14: note: declared here
  192 | gboolean     rsvg_handle_close  (RsvgHandle *handle, GError
**error);
      |              ^~~~~~~~~~~~~~~~~


librsvg source says
<https://gitlab.gnome.org/GNOME/librsvg/-/blob/main/include/librsvg/rsvg.h#L599>
rsvg_handle_close
was deprecated in librsvg 2.46.
