cc1plus: error: unrecognized command line option "-std=c++11"

i am trying install php-cpp on centos 6,5. when i run command make, i am getting error:

make: Warning: File `Makefile' has modification time 5.1e+05 s in the future
mkdir -p shared/common
mkdir -p shared/zend
mkdir -p shared/hhvm
g++ -Wall -c -g -std=c++11 -fpic -o shared/common/modifiers.o common/modifiers.cpp
cc1plus: error: unrecognized command line option "-std=c++11"
make: *** [shared/common/modifiers.o] Error 1

That flag was not added until a later version of g++ (4.7) to get the gcc 4.4 compat (as much as was there) you need to use the -std=c++0x flag.
