Hi, I thought I'd report my build experience. Using 5.2 from: <http://www.boost.org/doc/libs/1_60_0/more/getting_started/windows.html#or-build-binaries-from-source> It took about 15 minutes to figure out what to copy where and start the build. This was with VS2015 and the v140 toolset and VS2010/v100. but... <boost/locale.hpp> <boost/filesystem.hpp> <boost/asio.hpp> were missing . I just copied up from the likes of ..libs\filesystem\include\boost\filesystem.hpp, etc. to BOOST_ROOT/boost. Once that was done I compiled, linked, and ran fine. That was a 2010 project next I tried a 2015 project, it just uses different stuff, so I found geometry.hpp and the whole geometry folder were missing. ublas folder was missing from the numeric folder program_options folder was there but not boost/program_options.hpp assign.hpp and its folder missing lambda missing but i just ditched it and rewrote the artifact with a c++ lambda some phoenix file/folder? was missing forgot to write down just what. But all rest of the spirit stuff was there. Then it compiled, linked and ran fine. If I find more as I try other project, no big deal. Agent Ransack makes the fixes pretty fast. And I'm assuming I didn't miss a step as so many of the headers were in place. Best, Dan.
