Boost 1.61 binding problem

[sw897]

I build binding on windows using msvc2015. All the dependences were local built using mapbox/windows-builds. When building python binding, i get the error:

mapnik version 3.0.12 python-mapnik trunk boost 1.61 python 2.7.12

请问你的问题解决了吗？

Maybe try to build python-mapnik from v3.0.x branch. This branch keeps compatibility with 3.0.x versions of Mapnik.
