eclipse build error with regex

Question

I'm trying to implement regex in my parser program when i used codeblocks all works fine, on eclipse neon im having Function 'regex_match' could not be resolved error. I added flag to gcc c++ compiler settings -std=c++11 and checked CDT GCC Built-in compiler settings MiniGW. How to make it work on eclipse ?

    #include "ParserSip.h"
    #include <regex> //its included ok

    void checkIfCseq (SipMessage & pointer, string stringLine){     
    string stringToFind = ".*CSeq:.*";  
    regex_match(); // Function 'regex_match' could not be resolved 
    }
