upgrade to latest mapnik master

[mathisloge]

hi @artemp

do you plan to integrate the changes from the proj6 update or to update to the latest mapnik master?

[artemp]

@mathisloge can you give a bit more context here, please? node-mapnik works with latest mapnik@master, no?

[mathisloge]

Mostly. With the proj6 branch i think the proj_transform->source / dest functions were removed. So all logs like https://github.com/mapnik/node-mapnik/blob/f83bff5176c32a3c7819e5788e13ebcc3deed874/src/mapnik_projection.cpp#L318 are failing.

But these are just four lines which are invalid (only in mapnik_projection.cpp)

@mathisloge I see, thanks for highlighting this. I have local proj6 branch with all the fixes but never pushed, doh.. I'll need to update to latest master and to push proj6 branch, :+1:

[mathisloge]

@artemp if you have some spare time, could you push your proj6 branch? I would like to run the tests in https://github.com/mapnik/node-mapnik/pull/976 . Most of them are failing due to proj init grammar changes.

@mathisloge - I just pushed my local branch https://github.com/mapnik/node-mapnik/tree/proj6. Let me know if it works for you, cheers.

Thanks for pushing!

I'm still getting some erros with:

@mathisloge yep, proj6 branch needs updated mapnik-vector-tile https://github.com/mapbox/mapnik-vector-tile I just pushed https://github.com/mapbox/mapnik-vector-tile/tree/proj6 <---- It might need some tweaking but should work

[mathisloge]

@artemp thanks! Now all tests are running 👍
