btw, if you have further questions, post to the mapnik-users list as it’s unlikely I will bump into this post again.

ya, that’s a postgres config issue only.

To clarify, this is using the OSM-specific Mapnik wrappers described at http://wiki.openstreetmap.org/wiki/Mapnik. And I found the answer to my problem near the bottom of that page: http://wiki.openstreetmap.org/wiki/Mapnik#Troubleshooting. Evidently I had to remove all the authentication information and allow postgres to use ‘ident same user’ authentication.

Here’s what I ran:

$ ./generate_xml.py –dbname sfosm –host localhost –user jsha –accept-none
Include files written successfully! Pass the osm.xml file as an argument if you want to serialize a new version or test reading the XML

$ ./generate_image.py
Traceback (most recent call last):
File “./generate_image.py”, line 38, in
mapnik.load_map(m,mapfile)
RuntimeError: PSQL error:
fe_sendauth: no password supplied (encountered during parsing of layer ‘leisure’)

Then I changed the DB user to have a password, and re-ran generate_xml.py:

$ ./generate_xml.py –dbname sfosm –host localhost –password XXXX –user jsha –accept-none
Include files written successfully! Pass the osm.xml file as an argument if you want to serialize a new version or test reading the XML
$ ./generate_image.py

And that succeeded!

While I’ve got your attention, BTW, the render above seems to be missing a bunch of streets near the south end of the city, and in Treasure Island (the big island to the northeast). Do you have any ideas off the top of your head why that might be, and how I could fix it?

Mapnik should not have any problem with either an empty password string or leaving the password parameter out (whether from python or XML). More details on what you ran into would be great.

Thanks for the corrections, Keith! I’ve update the post to include them. Glad you found the guide helpful.

Excellent guide, also exactly what I was looking for. I had 2 problems with it:

1. The sed line should read

# sed -i s/tmpuser/$REALUSER/ .ecryptfs/$REALUSER/.ecryptfs/Private.mnt

2. I had to create the $REALUSER home directory before
# ln -s /home/.ecryptfs/$REALUSER/.* $REALUSER/

- it had naturally disappeared after the mv
