link: libboost_python3-vc140-mt-s-1_65_1.lib

Answer 2

While I have all this in my head........

Boost checks with whatever python include path you are using. And why not as you may want to work with 2.7 or 3.6. So the python include must be set in Additional Include Directories. I had mine set to 2.7 and had forgotten, my bad. I figured it out in that PY_MAJOR_VERSION is Python defined.

I still had linking issues, I just wanted to link static for now, but Boost Python will force dynamic linking of boost, regardless of user options. But that post fixes it.

Then I still did not have a libboost_python3-vc140-mt-sgd-1_65.lib and I had just done a b2 .. --build-type=complete install to be sure. I still had the console open so I looked up the list and boost python-s was built! For what ever reason b2 created a folder, C:\Boost\lib, just for the staticly linked python libs. All the other libs landed in C:\cpp\boost_1_65_0\stage\lib

What an adventure this has been!
