osm2pgsql usage

[Nakor Wikipedia]

   Hello,

First of all sorry if this is not the right place for those kind of issues. In this case please point me to where I should go.

I was in the process of setting up Mapnik and as a start I was using an OSM file from around my area to test with "small" data.

I get stuck with an error message in osm2pgsql:

osm2pgsql SVN version 0.67-18179

Using projection SRS 900913 (Spherical Mercator)
Setting up table: planet_osm_point
Setting up table: planet_osm_line
Setting up table: planet_osm_polygon
Setting up table: planet_osm_roads
Mid: Ram, scale=100

Reading in file: ../maps/Detroit_091010.osm
Processing: Node(434k) Way(50k) Relation(0k)osm2pgsql: osm2pgsql.c:262: StartElement: Assertion `xrole' failed.

I searched the web a bit but did not find much, except from some memories issues. I monitored the memory during the process and had at least 1Gb free, so I guess this is not the issue.

Any help would be appreciated.

  Thanks,

N.

On the OSM lists you'll find people more knownledgable about
osm2pgsql. But it seems like a problem with the data. The error
literally means: a member of a relation is missing a role tag. Are you
sure the data file is complete?

Have a nice day,

That assertion will trigger if you have a relation member without a
role= attribute. Normally all members in a relation have this even if
the string is empty.

There has been a suggestion that Xapi might return results without a
specified role[1]. I'll take a look at updating the osm2pgsql code to
cope with this.

Alternatively you might try downloading a data extract from somewhere
else like the CloudMade or Geofrabrik servers[2].
