Package: libmapnik3.1
Version: 3.1.0+ds-1+b4
Severity: important
Dear Maintainer,
I've been using osm-tile-tools (which I develop) on and off for ages
for rendering an OSM based map. This time it has been a couple of years,
I think, since the last time, so I'm not sure when this was introduced.
This project actually uses python3-mapnik, but the problem seems to come
from this library. In short:
In [1]: import mapnik
In [2]: p = mapnik.Projection('EPSG:4326')
RuntimeError: Cannot initialize projection 'EPSG:4326 ' without proj4
support (-DMAPNIK_USE_PROJ4)
As you can see below, it seems like libmapnik3.1 is not linking to
libproj25 (I guess; that's the one I can find installed locally). I'm
pretty sure the fix is an easy one.
Cheers,
-- Marcos.

Mapnik 3.x does not support PROJ >= 6:
https://github.com/mapnik/mapnik/issues/4036
If you really need the PROJ support in Mapnik, I suggest you get
involved helping maintain the package in Debian and start by backporting
the PROJ 6 changes like Fedora did for their package.
Your time may be better spent looking for alternatives to Mapnik as it's
not a particularly healthy project when it comes to releases.
python-mapnik still has no proper release since 2015.
Kind Regards,
Bas
