:After a bit of hard time I have succeeded to generate my boost static library on 64 using msvs 2015:
b2--cleanall --toolset=msvc-14.0 --linker=static --address-model=64
OK. Most of the functionalities I have tested worked fine. But when I include :#include <boost/timer/timer.hpp>and or
#include <boost/timer/config.hpp>
the linker error is generated: 
"Error LNK1104 cannot open file 'libboost_timer-vc140-mt-sgd-1_62.lib'"
well. there is  file with nearly same name  in a relevant directory: 
'libboost_timer-vc140-mt-gd-1_62.lib
so only gd but not sgd... What I am doing wrong?
2.  Is that could be better if I include option -a in my b2 command?
