Hello all, I'm running into some trouble using mapnik in a Linux Ubuntu
setting. I've got it successfully installed (i think). The issues are:
1. *from mapnik import Projection -* does not print the following lines for
me :
*registered datasource : raster
registered datasource : shape
registered datasource : postgis*
2. *Project(['init=epsg:42304'])* does not work for me:
*>>> from mapnik import *
>>> p = Projection(['init=epsg:42304'])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
Boost.Python.ArgumentError: Python argument types in
Projection.__init__(Projection, list)
did not match C++ signature:
__init__(_object*)
__init__(_object*, std::string)*
3. The current tutorial 1 (http://trac.mapnik.org/wiki/GettingStarted) fails
for me with the message:
*Traceback (most recent call last):
File "test.py", line 32, in <module>
lyr.datasource = Shapefile()
File "/usr/lib/python2.5/site-packages/mapnik/__init__.py", line 72, in
Shapefile
return CreateDatasource(keywords)
RuntimeError: failed opening file: Bad file descriptor*
This happens even if I modify the line "*Shapefile(file="....")*" to just "*
Shapefile()*". I tried many possible values for the parameter "file"
(relative, absolute, etc) for the zipfile and the contents of the zipfile
from here: *http://www.census.gov/geo/www/cob/vt2000.html#shp*
Thanks, and let me know if anything is unclear.

Also, I noticed that the installation instructions for Mapnick is wrong. It
doesn't state libboost_iostream development headers as a prerequisite.
Also, it would be nice to state what minimum version of g++ is required for
installation. I had version < 3.0 and the scons job was failing without a
good explanation.
