Thanks so much for your help. I now (finally!) have a working mapserver...

Here's my tilecache.cfg:

[cache]
type=Disk
base=/tmp/tilecache

[osm]
type=Mapnik
mapfile=/home/eamorr/maps/mapnik/osm.xml
spherical_mercator=true

And here's the html/javascript:

<head>
<style type="text/css">
html, body { height: 100%; }
body {margin: 0px;}
#map{
width: 100%;
height: 100%;
}
</style>
<script src="http://openlayers.org/api/OpenLayers.js"></script>

<script type="text/javascript">
var map;

function init() {

var options = {
maxResolution: 156543.0339,
units: 'm',
projection: new OpenLayers.Projection("EPSG:900913"),
maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34, 20037508.34, 20037508.34)
};

map = new OpenLayers.Map("map", options);

/*
Works with a tilecache.cfg layer entry like:

[osm]
type=Mapnik
mapfile=/full/path/to/osm.xml
spherical_mercator=true

**Your OSM data in postgis must be in EPSG 900913 or Spherical Mercator**

Edit the below parameters to fit your setup:

*/

// default url of tilecache_http_server.py
var server_url = "http://maps.myserver.com/tilecache/tilecache.cgi?";

// Must match tilecache config layername
var layer_name = "osm";

var image_type = "png";
// force regeneration even if cache is hit
//var image_type = "png?FORCE=1";

var wms = new OpenLayers.Layer.WMS("TileCache Mapnik Layer",server_url,
{ serviceVersion: "1.0.0", layers: layer_name, type: image_type });

var official_tiles = new OpenLayers.Layer.OSM("Mapnik from OSM");

map.addLayers([wms,official_tiles]);
map.addControl(new OpenLayers.Control.Scale('scale'));
map.addControl(new OpenLayers.Control.Navigation());
map.addControl(new OpenLayers.Control.PanZoom());
map.zoomToMaxExtent();
}
</script>
</head>

<body onload="init()">
<div id="map"></div>
</body>

This may be of help to someone in future.

Best wishes from Ireland,

Eamorr

Eamorr,

Your configuration does not look quite right, and can be more simple.

I've just added a few example files for you at Mapnik-utils. See:

http://code.google.com/p/mapnik-utils/source/detail?r=787

You'll need to point the OL code at your tilecache.cgi or just use the
provided (by tilecache) local http server which by default mounts at

http://localhost:8080

Cheers,

Dane
