How to enable osm.input plugin?

[csytsma]

When running from latest source (Version 0.10.2 (v0.10.1-395-gff87d20)) , using .osm files as a layer is not supported, which it is under 0.10.1 packaged versions for MacOS.

1. Can this be re-enabled? Why was it removed? Is it a Mapnik issue?

2. Alternatively, I've tried to include the osm.input in my local source, but when running I get the following error:

Problem loading plugin library: /Users/xxx/Development/Tilemill/tilemill/node_modules/mapnik/lib/binding/node-v46-darwin-x64/mapnik/input/osm.input (dlopen failed - plugin likely has an unsatisfied dependency or incompatible ABI)

I can't figure out how to satisfy the osm.input plugin dependency.

Thanks in advance.

Does anyone know why this plugin was removed? Can it easily be added back?

You'll need to build node-mapnik against a version of mapnik that has the OSM plugin built, and use the --build-from-source flag when installing with npm.

When you just do npm install it downloads a binary blob from Mapbox for node-mapnik, which has whatever they compiled it with.

I would also suggest not using the OSM plugin, because it doesn't work well, work with large files, handle multipolygons correctly, or get much use.
