Build with VS2017

[NobilisNC]

Hello,

I have compiled mapnik with VS2015, but my project use a lot of c++17 features, and when I want to use mapnik inside, The program crashed because of different CRT (bug is appearing when I have to std::move something from my program to a Mapnik function).

Exemple

 feature_type_style raster_style;
    {
      rule r;
      {
        raster_symbolizer raster_sym;

        r.append(raster_sym);
      }
      raster_style.add_rule(std::move(r)); // <-- Here it crashes
    }
    m.insert_style("raster_style", raster_style); // Or here, if I comment the above live

So, I decided to compile Mapnik with VS2017 and I succeed to compile mapnik.dll thanks to VS project (.sln) created in packages\mapnik-v3.0.x\mapnik-gyp\build The problem I have now is everything works with mapnik but I need to compile all his dependecies to VS2017. But I did not fully understand how they are building. Is there a .sln somewhere ? With CMake ?

Thanks :)

@NobilisNC sorry to let you know, but this repository is not maintained anymore and we do not provide any further support.

I decided to compile Mapnik with VS2017 and I succeed to compile

While the build might have succeeded I suppose the resulting mapnik.dll was still built with VS2015 build tools nevertheless, as everything else is disabled (no VS2017 support): https://github.com/mapbox/windows-builds/blob/master/settings.bat#L82

Dependencies could be built by passing the "FASTBUILD=0" flag to settings.bat: https://github.com/mapbox/windows-builds#creating-binary-mapnik-dependencies-packages-mapbox-specific

However you would also have to update these dependency build scripts (https://github.com/mapbox/windows-builds/tree/master/scripts) to work with VS2017.

https://github.com/mapnik/mapnik-gyp would also have to be updated to VS2017 as this is the repository that does the actual build.
