Looking at this page?https://gcc.gnu.org/projects/cxx-status.html?209?I am guessing if you compiler is not >= version 4.9 then you will need to upgrade it
If your compiler does support c++14 then you need to set a flag to -std=c++14 to tell the compiler to use c++14
if building from source I think you would do the following
in CMakeCache.txt file find?CMAKE_CXX_FLAGS:STRING=?and set it to?CMAKE_CXX_FLAGS:STRING=-std=c++14
or?CMAKE_CXX_FLAGS:STRING=-std=c++1y
or take a look at this
