C ++ Netbeans连接到MySQL给出错误

Question

I am trying to create a C++ program on netbeans( and on win 7) that connects to a MySQL server.I'm using the library's that i got from MySQL

#include <cppconn/driver.h>
#include <mysql_driver.h>
#include <mysql_connection.h>


int SQLConnection(){

sql::mysql::MySQL_Driver *driver;
sql::Connection *con;

driver = sql::mysql::get_mysql_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306", "user", "password");
delete con;
}

But i keep getting this error.

Any advise?

Can you try to make a raw compile of this? put into the linker mysqlcppconn.lib !

#include "mysql_connection.h"
#include "mysql_driver.h"
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>

int main(){

sql::Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
sql::ResultSet *res;
sql::Statement *pstmt;

try{
driver = get_driver_instance();
con = driver->connect("localhost", "root", "root");
con->setSchema("test");
stmt = conn->createStatement();

/*blah blah yada yada*/

}catch(sql::SQLException &e){
    std::cout<<e.what();
}
