从Mysql网站运行代码示例会导致std :: bad_alloc

Question

我从https://dev.mysql.com/downloads/connector/cpp/下载了mysql C ++连接器包。我写了一个使用它的简单程序。以下是代码。此代码实际上是https://dev.mysql.com/doc/connector-cpp/en/connector-cpp-examples-complete-example-1.html

的示例代码的一部分

#include <cppconn/driver.h>
int main(void)
{
  sql::Driver *driver;
  sql::Connection *con;

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

  delete con;

  return 0;
}

运行它会产生以下错误消息：

[frank@arch mysql-connector-c++]$ ./a.out 
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted (core dumped)

为什么不起作用？
