The following error occurs when attempting to build nix against boost 1.60.0

Is this related to the change in boost::none in 1.60.0? Changed the implementation of boost::none again. Now it is a const object with internal linkage (as any other tag). This fixes #11203.

Hello Achilleas, as far as I can tell the error is indeed related to the changes in boost 1.60.0. Until this issue is resolved it is best to use boost versions from 1.55 to 1.58.

Thanks for the response. I'll hold back updating until it's resolved.

I have a patch to fix this in the split_variant branch. I will try to get some more work done in that branch to make the split more useful and then create a pull request.
