When I run scons/scons.py -h I see amongst other stuff
Checking for C library pq... no
INPUT_PLUGINS: Input drivers to include
(all|none|comma-separated list of names)
allowed names: postgis shape raster gdal
default: all
actual: postgis shape raster gdal
does this mean i have the postgis.input plug-in or not?
at the moment i have postgres-server-8.2-dev and libpq-dev installed. don't
know if thats enough.
i compiled and installed mapnik with DEBUG=yes successfully and when i start
generate_image.py I see:
...
start layer processing : amenity
datasource = 0
end layer processing
...
this holds true for all the datasources that point to the postgis database.
