After successfully working with node-mapnik (and the gorgeous vector tiles) on Linux I'm trying to set them up on Windows too, but have come to a dead end.

What I've done so far:

  • Installed mapnik 2.2.0 SDK and added the bin and lib directories to the PATH.
  • Using npm install mapnik shows an error about a missing cairo header file.
  • Cloning the repository and adding the cairo directory to binding.gyp solved the header issue.
  • Next error is about the target architecture (32 vs. 64bit), because the generated solution is 64bit only. I solved this by adjusting the gyp config parameters to get a Win32 target.
  • Next errors are about missing boost libraries. I followed the tutorial on how to build mapnik dependencies on Windows to the letter and added the boost-49-vc100\lib directory to the AdditionalLibraryDirectories. Which results in this error:

    Creating library C:\dev2\node-mapnik\node-mapnik\build\Release\_mapnik.lib and object C:\dev2\node-mapnik\node-mapnik\build\Release\_mapnik.exp LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library [C:\dev2\node-mapnik\node-m apnik\build\_mapnik.vcxproj] mapnik_image_view.obj : error LNK2001: unresolved external symbol "void __cdecl boost::throw_exception(class std::exception const & )" (?throw_exception@boost@@YAXABVexception@std@@@Z) [C:\dev2\node-mapnik\ node-mapnik\build\_mapnik.vcxproj] C:\dev2\node-mapnik\node-mapnik\build\Release\_mapnik.node : fatal error LNK1120: 1 unresolved externals [C:\dev2\node-mapnik\node- mapnik\ build\_mapnik.vcxproj]

Any suggestions on how to get node-mapnik (with vector tile support) running on Windows?

I think the problem is a linking issue: you likely need /MD while /MT is being set. See Step 3 in my comment at https://github.com/mapnik/node-mapnik/issues/202#issuecomment-31876610.

Solution (tested on W7-64 with node.js-32. 64bit currently not supported):

  • use node-mapnik from Github
  • get cairo sources: http://www.cairographics.org/
  • copy cairo-svg-surface.c, cairo-svg.h and cairo-svg-surface-private.h to C:\mapnik-v2.2.0\include
  • make proj4 epsg files available: SET PROJ_LIB=C:\mapnik-v2.2.0\share\proj
  • now npm install should finish successfully, provided that all other requirements are met: mapnik SDK, Python, protobuf, etc, ...
  • register all needed input plugins in your script (not auto registered in current Github source) e.g. shapefile input: mapnik.register_datasource(path.join(mapnik.settings.paths.input_plugins,'shape.input'));
