Boost-python failure to build basic example demo

Hello, I am trying to compile the quickstart example for the boost-python project, but I can't seem to succeed. I was hoping someone from the mailing list could point me to the right direction. I am trying to follow the official documentation (https://www.boost.org/doc/libs/1_62_0/libs/python/doc/html/building/no_inst… etc) ,but seem to have to do a lot of extra steps, and still without result: My current approach: * (On a windows machine, having visual studio community 2017 installed, and so also the MSVC, as well as python 3.5) * Download boost_1_68_0 and extract into C:\boost_1_68_0 * Run bootstrap If I then try to follow the official documentation, the build fails with: C:\boost_1_68_0\libs\python\example\quickstart>..\..\..\..\.\b2 warning: no Python configured in user-config.jam warning: will use default configuration ...found 26 targets... ...updating 11 targets... msvc.write-setup-script ..\bin\standalone\msvc\msvc-14.1\msvc-setup.bat compile-c-c++ extending.obj extending.cpp extending.cpp(5): fatal error C1083: Cannot open include file: 'boost/python/class.hpp': No such file or directory I figured out that by modifying the higher-level Jamroot file, that by adding "<include>C:\\boost_1_68_0", I can at least get further. The next error I run into is: C:\boost_1_68_0\libs\python\example\quickstart>..\..\..\..\.\b2 warning: no Python configured in user-config.jam warning: will use default configuration ...patience... ...patience... ...found 1400 targets... ...updating 6 targets... compile-c-c++ extending.obj extending.cpp msvc.link.dll extending.pyd LINK : fatal error LNK1181: cannot open input file 'boost_python.lib' I then "guessed" that I needed to manually build this library first, and so I ran: "C:\boost_1_68_0>.\b2 --with-python -j4". This then builds some libraries, like "libboost_python35-vc141-mt-gd-x32-1_68.lib". This still does not fix any build. Only when I manually copy the libraries to the example folder, and rename them, it finally tries to link, but then gives a lot of other errors. (See attachment) I am clearly missing something here in either the build tool (never used jam before), or in my procedure. Can somebody perhaps enlighten me with the correct procedure? Thanks in advance! Arnout
