我在Windows 8上使用Code::Blocks 13.12MingW 4.8.1。 我尝试以动态和静态方式链接MySQL C++ Connector 1.1.4。 编译时没有给出错误,但是当启动exe时它停止工作。

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;
}

建筑物没有给出错误:

以下是gdb

该计划在此行失败:

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

有人可以帮忙让它发挥作用吗?

2 个答案:

答案 0 :(得分:0)

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

你有一个以上,MySQL网站有以下代码。

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

我没有看到太大的区别。您确定用户名,密码和端口与您在代码中提到的相同吗?

答案 1 :(得分:0)

好!问题是我的IDE。似乎MySQL Connector C++ 1.1.4 Microsoft Visual C++ 2003或更高版本一起使用。

如果您遇到同样的问题,只需安装Microsoft Visual C++ 2003或更新版本并正确链接库。 http://dev.mysql.com/doc/connector-cpp/en/connector-cpp-apps-windows-visual-studio.html
