hi, I have seen some mapnik reply mails :
http://lists.berlios.de/pipermail/mapnik-users/2007-July/000339.html https://lists.berlios.de/pipermail/mapnik-users/2007-June/000300.html and the page : http://trac.mapnik.org/wiki/OptimizeRenderingWithPostGIS My question is as follows: I have added the following code to rundemo.cpp ! { parameters p; p["type"]="postgis"; p["host"]= "abc"; p["port"]=5432; p["dbname"]="gis"; p["user"]="anisha"; p["password"]=""; p["table"]="tree"; Layer lyr("Roads"); lyr.set_datasource(datasource_cache::instance()->create(p)); lyr.add_style("roads"); } I have installed the postgis plugin through this command : Que 1: Now how i am supposed to check whether a table tree has been created or not ? Que 2: Where should write the query "select * from tree", in rundemo.cpp ? This query is supposed to be independent of table creation !!
