Hi Dane, Thanks for the response, I've been digging around the issue too. And I am not convinced it's to do with the python version, because your mapnikserv.py script works fine, so there shouldn't be any problem rendering and displaying map files using the mapnik ogcserver.
I did a google search on the fromfd() member function for the socket class in python. And it seems that there were some issues for fromfd() to run on windows. (check http://bugs.python.org/issue1378). It is also indicated on the python documents that formfd() only works on BSD socket not Winsock (http://www.python.org/doc/2.5.2/lib/module-socket.html). Though, I don't see why this issue was not addressed in the later version of python (I am already on python 2.5.2) I was playing with tilecache as well, though I am still not sure how I could link tilecache to a local mapnik server (i.e. I think I need to modify the configuration file so it to point to a local "working" ogcserver.cgi script). Connecting to remote WMS servers seems to work on the testing tilecache scripts already. (In my case, it cached map tiles from remote servers, and store the map tiles in a tile directory specified by the configuration script). Kind regards, Po Cheng P.S. Doing this map serving thing on Windows is also a part of the research I am doing. (Otherwise, I would have already installed a Linux box. >_< ) Dane Blakely Springmeyer wrote: > Hi Po, > > Yes, TileCache and Mod_tile are both better options for OSM data because > they can cache tiles and avoid needing to render tile dynamically (which > is expensive with the large OSM styles). > > If you try TileCache it can run in both cgi and mod_python mode, which > should be a bit easier to set up on windows. > > Thats cool you got the mapnikserv testing script running on windows (I'd > be interested in the steps involved if it took anything special). > > Regarding the OGCServer errors with fastcgi, it looks like the problem > is mismatched python versions.
