Connection Crash in mysql C++ -

currently, have implemented program write mysql database... using xcode c++as well. have imported libraries correctly i'm getting bad excess error message on line :

    con = driver->connect("tcp://127.0.0.1:3306", "root", "root"); 

what seems issue? heres full program...

#include <stdlib.h> #include <iostream>  // include directly different // headers cppconn/ , mysql_driver.h + mysql_util.h // (and mysql_connection.h). reduce build time!  #include "mysql_connection.h" #include <cppconn/driver.h> #include <cppconn/exception.h> #include <cppconn/resultset.h> #include <cppconn/statement.h> using namespace std; int main(void) {     cout << endl;     cout << "running 'select 'hello world!' _message'..." << endl;     try {         sql::driver *driver;         sql::connection *con;         sql::statement *stmt;         sql::resultset *res;         // create connection          driver = get_driver_instance();          con = driver->connect("tcp://127.0.0.1:3306", "root", "root");         // connect mysql test database         con->setschema("test");         stmt = con->createstatement();         res = stmt->executequery("select 'hello world!' _message");          while (res->next()) {             cout << "\t... mysql replies: ";             // access column data alias or column name             cout << res->getstring("_message") << endl;             cout << "\t... mysql says again: ";             // access column fata numeric offset, 1 first column             cout << res->getstring(1) << endl;         }          delete res;         delete stmt;         delete con;      } catch (sql::sqlexception &e) {         cout << "# err: sqlexception in " << __file__;         cout << "(" << __function__ << ") on line " << __line__ << endl;         cout << "# err: " << e.what();         cout << " (mysql error code: " << e.geterrorcode();         cout << ", sqlstate: " << e.getsqlstate() << " )" << endl;     }     cout << endl;     return exit_success; } 

edit currently, looked @ topic similar mine still lost... how recompile mysql cmake , change such flags?

i have been @ issue several hours , no coding has been done... staring @ screen face >:(.

here's similar problem (almost identical?), have checked it?
