I don't think so.

It compiled successfully ( $ g++ test.cpp -o test -lboost_system
-lboost_thread ) with GCC-Boost v-1.54 but while linking and execution it
gives error as shared.

I think if I can know - How to support lexical or what is the build command
to support lexical analysis of Boost during Boost-v1.54 build process with
toolset of gcc? I do see lexical_cast.hpp file in include file of
Boost-v1.54 while building.
