    Convert Const Char * to string

    Code:
    #include <string>
    
    void
    Calc::yyerror(const char * mesg) {
    string x;
    
      // how can i make this to work ??? I would like to copy the mesg to the x string.
       x = mesg;
    
    
    }

    How can you make it work? It should work exactly as you have it written in your example above. One of the assignment operators for the string class takes a constant pointer to character as an argument.

    make sure you have "using namespace std;" or do this to declare the string:
    std::string x;
