Hỏi về lỗi khi thêm thư viện SDL vào Dev c++

[muc_tieu (minh)]

Mình tìm hiểu trên mạng cách thêm thư viện SDL vào dev c++ và thực hiện theo đúng các bước của bài viết này: “Series hướng dẫn dùng SDL cơ bản”
Nhưng khi mình test 1 chương trình c++

#include <windows.h>
#include <iostream>
int main()
{
	std::cout << "hello";
	return 0;
}

thì nó hiển thị ra lỗi này:

Mong mấy ace giúp mình xử lý lỗi này với? Cảm ơn!
