Hi. I was trying to render some tiles from OpenStreetMap, but mapnik gets it wrong - see the attachment, one picture for thousand words. In the first place it is obvious that it does not get the fonts correctly, as there are empty rectangles in the place of some names. Using the same dataset and the same database setup etc., I was able to get the map rendered correctly on a Fedora system. So that there is something rotten within Gentoo ... I'm no Python expert to debug :-/ Reproducible: Always Steps to Reproduce: 1. Follow the instructions at http://wiki.openstreetmap.org/index.php/Mapnik to get a working setup. Get the dataset from http://kubajz.kbx.cz/junk/osm/czechia-latest.osm.bz2 2. Within the script generate_image.py, set the bounding box to: ll = (15.7, 49.16, 16, 49.25) 3. Run generate_image.py 4. Use some GIMP magic to crop the image :-) Actual Results: see the attachment gentoo.png Expected Results: see the attachment fedora.png # emerge --info WARNING: repository at /root/portage is missing a repo_name entry * Overlay eclasses override eclasses from PORTDIR: * * '/usr/portage/local/layman/kde-testing/eclass/kde4-base.eclass' * '/usr/portage/local/layman/kde-testing/eclass/kde4-functions.eclass' * '/usr/portage/local/layman/kde-testing/eclass/kde4-meta.eclass' * * It is best to avoid overriding eclasses from PORTDIR because it will * trigger invalidation of cached ebuild metadata that is distributed with * the portage tree.

Okay, if you wait a bit and sync again, there's an updated version you can try. I had to switch the postgresql dep to get the plugin to build, so give this one a try and see what it does for you...
(In reply to comment #3) > Okay, if you wait a bit and sync again, there's an updated version you can try. > I had to switch the postgresql dep to get the plugin to build, so give this > one a try and see what it does for you... unfortunately, I've got some troubles resolving postgresql package conflicts, but as for mapnik itself, there is one problem: $ ./generate_image.py Traceback (most recent call last): File "./generate_image.py", line 16, in <module> from mapnik import * File "/usr/lib64/python2.5/site-packages/mapnik/__init__.py", line 32, in <module> from paths import inputpluginspath, fontscollectionpath File "/usr/lib64/python2.5/site-packages/mapnik/paths.py", line 4 fontscollectionpath = /usr/share/fonts/dejavu/ ^ SyntaxError: invalid syntax ... simply adding quotation marks around the path helps I'll report back as I get that damn database installed correctly again (hints appreciated ...)
so after unmasking the right postgresql packages, deleting --force-silent form the initscript to find out I have to modify the shm limit etc., finally I managed to render something with mapnik, and it works as expected => this appears to be fixed, thanks a lot! (not closing the bugreport for now, as the problem mentioned in comment #4 does not seem to be fixed yet)
Sorry about that... The sed invocation that modifies the font path inadvertently omitted the single quotes. Should work fine now...
