Dear List, First, my appologies that I am completely new to Mapnik. Any help is useful to me.
I've recently tried to set up a map server using MS-Windows 2003 server (std ed). So I've followed installation procedures on http://wiki.openstreetmap.org/index.php/Mapnik Installed: PostgresSQL 8.3 with PostGIS 1.3.3 extension Some map information for UK imported to PostGIS using osm2pgsql Python2.5 on C:\python25 ActivePerl5.10 on C:\Perl mapnik-0_5_1 Win32 binary (Unzipped) and put in c:\mapnik-0_5_1 Copied the site-packages to c:\python25\Lib\site-packages Set the path to include c:\Python25, etc. The " from mapnik import * " runs fine in python Then test with demo\python\rundemo.py runs perfectly with 3 images of easter canada (ottawa, montreal) generated. So far so good! I then Downloaded mapnik scripts (svn.openstreetmap.org/applications/rendering/mapnik) and put in d:\mapnik unzip (http://tile.openstreetmap.org/world_boundaries-spherical.tgz and http://hypercube.telascience.org/~kleptog/processed_p.zip) to :\mapnik\world_boundaries\ After modifying the set-mapnik-env to set-mapnik-env.bat (with export changed to SET in DOS batch scripts and call %* to run arguments) The " set-mapnik-env.bat customize-mapnik-map.pl > osm.xml " command in DOS prompt succeeded (no errors given). But when do command " set-mapnik-env.bat generate_image.py " The python gives an error saying this ===================================================== D:\mapnik>set-mapnik-env.bat generate_image.py got exception ... Traceback (most recent call last): File "D:\mapnik\generate_image.py", line 37, in <module> load_map(m,mapfile) RuntimeError: failed opening file: The handle is invalid. ===================================================== The same RuntimeError occurs when I try " set-mapnik-env.bat generate_tiles.py " and too with the hello_world python with XML mapfile example from http://trac.mapnik.org/wiki/ExampleCode I tried to look at the source code of load_map() function from http://prdownload.berlios.de/mapnik/mapnik_src-0.5.1.tar.gz But failed to understand why load_map() from load_map.cpp would fail. As far as I understand, it seems like an error trying to open mapfile (which set to d:\mapnik\osm.xml in set-mapnik-env.bat) from the python error message. And I double-checked that the osm.xml is there. Any ideas?
