连接崩溃在mysql c + +

Question

目前，我已经实现了一个程序来写入到mysql数据库...我也使用Xcode与c + +。我已经正确导入了所有的库，但是我在这一行上收到了一个BAD EXCESS错误消息：

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

什么似乎是问题？继承人的全部程序...

#include <stdlib.h> 
#include <iostream> 

// Include directly the different 
// headers from cppconn/ and mysql_driver.h + mysql_util.h 
// (and mysql_connection.h). This will reduce your 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!' AS _message'..." << endl; 
    try { 
     sql::Driver *driver; 
     sql::Connection *con; 
     sql::Statement *stmt; 
     sql::ResultSet *res; 
     // Create a connection 
     driver = get_driver_instance(); 

     con = driver->connect("tcp://127.0.0.1:3306", "root", "root"); 
     // Connect to the MySQL test database 
     con->setSchema("test"); 
     stmt = con->createStatement(); 
     res = stmt->executeQuery("SELECT 'Hello World!' AS _message"); 

     while (res->next()) { 
      cout << "\t... MySQL replies: "; 
      // Access column data by alias or column name 
      cout << res->getString("_message") << endl; 
      cout << "\t... MySQL says it again: "; 
      // Access column fata by numeric offset, 1 is the 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; 
} 

编辑所以目前，我看着这个topic这是几乎完全相似，我的，但我仍然这样就失去了......我怎么会重新编译MySQL的使用CMake和变化这样的标志？

我一直在这个问题上几个小时，没有编码确实已经完成......就在我盯着屏幕与面容> :(。

这里有一个类似的问题（几乎相同？），有你检查了吗？
