[OSM-newbies] Setting up mapnik

[Sebastian Mauer]

Yep, my osm.xml in fact is there ;) ...all I want to do is either set up
mod_tile (which has a rather incomplete documentation) or tilecache (which
does not seem to work with mapnik-0.5.1)

Error tilecache:

An error occurred: 'module' object has no attribute 'rawdata'
  File "/var/www/enexigo/web/wms-c/TileCache/Service.py", line 198, in
modPythonHandler
    host )
  File "/var/www/enexigo/web/wms-c/TileCache/Service.py", line 182, in
dispatchRequest
    return self.renderTile(tile, params.has_key('FORCE'))
  File "/var/www/enexigo/web/wms-c/TileCache/Service.py", line 119, in

    data = layer.render(tile)
  File "/var/www/enexigo/web/wms-c/TileCache/Layer.py", line 250, in render
    image = self.renderMetaTile(metatile, tile)

    data = self.renderTile(metatile)
  File "/var/www/enexigo/web/wms-c/TileCache/Layers/Mapnik.py", line 59, in

    im = PIL.Image.fromstring('RGBA', tile.size(), mapnik.rawdata(im))

Im glad the instructions worked!
