Point shapefile freezes mapnik

Rate this Message:
Dear all,
I've been trying to render a simple point shapefile, however mapnik just locks up (using 100% of one core). I've tried this both in pure python and using an xml map file (see extract below). It renders the world_borders shapefile in the Hello World example beautifully, but it won't do a simple point shapefile! Version: 0.600 OS: Ubuntu Jaunty Can anyone help please? Cheers, Will T <Style name="Style2"> <Rule> <PointSymbolizer file="/tmp/pub.png" width="16" height="16" type="png" /> </Rule> </Style> <Layer name="points" srs="+proj=latlong +datum=WGS84"> <StyleName>Style2</StyleName> <Datasource> <Parameter name="type">shape</Parameter> <Parameter name="file">pointtest.shp</Parameter> </Datasource> </Layer> |

Hi Will,
Welcome to Mapnik! Could you post your shape file somewhere to have a look. Also, could you provide more info about your setup.

Thanks for the quick response, Artem.
I've put the shapefile up at: http://map.nsms.ox.ac.uk/media/temp/pointtest.zip My system is a Dell Optiplex 755 with intel core2 duo, running ubuntu jaunty jackalope (9.04). I built mapnik with cairo support. I've just done a debug build on an ubuntu hardy 8.0.4.1 server - Dell poweredge quad core. I get the same problem. It's a multipoint shapefile - I wonder if that has anything to do with it? Cheers Will 2009/6/11 Artem Pavlenko <artem@...>: > Hi Will, > > Welcome to Mapnik!

OK, just tried this out with a simple point shapefile (no multipoints)
and it ran perfectly. At least I've got a workaround now. Must be a bug with multipoint shapefile handling, no?
