I'm running mapnik version 0.5.1 as shipped with Debian Lenny. Following http://wiki.openstreetmap.org/wiki/Mapnik/Installation#For_Debian_Lenny_or_Sid, this should be ready to work.
Also, I have downloaded the latest SVN revision from http://svn.openstreetmap.org/applications/rendering/mapnik and done the steps described on http://wiki.openstreetmap.org/wiki/Mapnik#Rendering_with_Mapnik. I have imported the extract for the UK (http://nick.dev.openstreetmap.org/downloads/planet/uk-090701.osm.bz2) with osm2pgsql. No problem with the import and everything looks good in the PostGIS db. The following tables are populated with reasonably looking data: Schema | Name | Type | Owner --------------+------------------------+----------+------------ public | planet_osm_line | table | hansm public | planet_osm_nodes | table | hansm public | planet_osm_point | table | hansm public | planet_osm_polygon | table | hansm public | planet_osm_rels | table | hansm public | planet_osm_roads | table | hansm public | planet_osm_ways | table | hansm osm=> SELECT * FROM geometry_columns; f_table_catalog | f_table_schema | f_table_name | f_geometry_column | coord_dimension | srid | type -----------------+----------------+--------------------+-------------------+-----------------+--------+------------ | public | planet_osm_point | way | 2 | 900913 | POINT | public | planet_osm_line | way | 2 | 900913 | LINESTRING | public | planet_osm_polygon | way | 2 | 900913 | POLYGON | public | planet_osm_roads | way | 2 | 900913 | LINESTRING When trying to render tiles with generate_tiles, I only get PNG files with waterbodies and land, but not the actual OSM features. This is independend from the zoom level. When checking my PostgreSQL log files, I see malformed SQL queries issued by mapnik. Obviously, it does not know about the tables' geometry columns: select asbinary() as geom,"highway","railway" from (select way,highway,railway, case when tunnel in ('yes','true','1') then 'yes'::text else tunnel end as tunnel from planet_osm_roads where highway is not null or railway is not null order by z_order ) as roads where && setSRID('BOX3D(-19724422.27493316 7200979.560689881,-18472078.00350883 8453323.832114212)'::box3d,537534573) Now my big question: How do I explain mapnik that it has to use "way" as geometry column?
