c++ - EXE 编译后停止工作。 (Mysql C++ 连接器)

Question

我在 Windows 8 上使用 Code::Blocks 13.12 和 MingW 4.8.1。 我尝试以动态和静态方式链接 MySQL C++ Connector 1.1.4。 编译时它不会出错，但是当启动 exe 时它会停止工作。

我尝试了以下代码:

#include <iostream>
#include "mysql_connection.h"
#include "cppconn/driver.h"

using namespace sql;

int main() {
    Driver *driver;
    Connection * con;
    std::cout << "1\n";
    driver = get_driver_instance();
    std::cout << "2\n";
    con = driver->connect("TCP://127.0.0.1:3306", "test", "test");
    std::cout << "3\n";
    return 0;
}

构建不报错:

这是gdb给出的日志:

1 和 2 在控制台上打印成功，但 3 没有。 进程返回 255 (0xFF)。

程序在这一行失败:

con = driver->connect("TCP://127.0.0.1:3306", "test", "test");

任何人都可以帮助它工作吗？

Answer 1

con = driver->connect("TCP:://127.0.0.1:3306", "test", "test");

你有上面的代码，MySQL 网站有下面的代码。

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

我看不出有什么区别。您确定用户名、密码和端口与您在代码中提到的相同吗？
