boost::spirit::x3[1.63.0] calc1.cpp compilation error using g++

Hi,

I tried compiling (g++ -O3 -w -std=c++11 -I. -I/grid/common/pkgs/boost/v1.63.0/include calc1.cpp) [gcc version: 4.8.3]

https://www.boost.org/doc/libs/1_63_0/libs/spirit/example/x3/calc/calc1.cpp

and get tons of errors. Please see the log below.

Can you please help me figure out what is going wrong?

Thanks!
