mapnik.render causing segmentation fault
by Philip Stubbs-2

Rate this Message:
Hi all,
I am new hear but I don't know where else to look. I have installed mapnik and am trying to get the generate_tiles script to work. It is causing a segmentation fault when mapnik.render is called. I have tried the 'hello world' example and that works, but I notice that uses mapnik.render_to_file. Therefore I tried to adjust that script to use the mapnik.render method, and it also then seg faulted. I am not a programmer, and what little I do know is not in Python :-( My Google foo is also weak today. Any help would be appreciated.

Philip,
Are you running Mapnik 0.6.1 and debian sid or ubuntu karmic? If so you'll likely need to upgrade to Mapnik trunk, as we've recently fixed a bug that slipped into 0.6.1 that would cause segfaults when reading from shapefiles: http://trac.mapnik.org/ticket/436 Before you do this you could try commenting out the xml <Layer> definitions that reference shapefiles in the osm.xml and see if that fixed the problem.

Any help would be appreciated. Ops! Should have said that I am running Ubuntu 9.10, I installed python-mapnik and Postgres from the Ubuntu repositories, and followed the set-up guide from the openstreetmap wiki. Now I have made a copy of the generate_image.py script and changed it to use mapnik.render_to_file, and it has just successfully rendered an image of the UK. This is going to be of more use to me than the tiles, so I think I am sorted. Still, it would be good to know why the one method works when the other does not. I may in the future want a local tile server. -- Philip Stubbs _______________________________________________ Mapnik-users mailing list Mapnik-users@... https://lists.berlios.de/mailman/listinfo/mapnik-users |

Thanks for the added details Philip.
If changing the render method fixed the problem then that may not be the bug I previously mentioned. I'm running a beta release of 9.10 and have not seen this problem, but I will try to get the release going to test further. It would be great if you could provide the output of: $ apt-cache show python-mapnik Thanks, Dane On Nov 1, 2009, at 1:13 PM, Philip Stubbs wrote: > 2009/11/1 Philip Stubbs <philip@...>: >> Hi all, >> >> I am new hear but I don't know where else to look.

Try editing the script to set: NUM_THREADS = 1 For reference, what OS & Mapnik version are you running?
