c++ - 将 sdl 与 g++ 链接时出现错误

Question

我知道很多人都遇到过这样的问题，但是没有一个解决方案在我链接到 SDL 时有效，我的代码如下:

#include <SDL/SDL.h>
#include <iostream>

int main()
{
    return 0;
}

我使用命令行 g++ 继承命令:

g++ main.cpp -o application -Wall -Ideps/include -Ldeps/lib -lSDL2 -lSDL2main

我在:

C:\users\user\desktop\my_stuff\code\visual_studio_code\c++\graphics

图形有:

deps
  include
    SDL
    GL
  lib
    libs
main.cpp

我使用 -v 获取此输出:

我正在尝试设置 Visual Studio 代码以正确编译 C++。

我也知道我可以使用代码块或 visual studio 2015 或其他东西，但我有两个理由不这样做。1. 我与 4 个有时 5 个其他人共享这台计算机，硬盘已满，visual studio 至少为 4GB2. 我也有点想知道怎么做

试试这个:

Under Visual C++, you need to link with SDL2main.lib. Under the gcc build environments including Dev-C++, you need to link with the output of "sdl-config --libs", which is usually: -lmingw32 -lSDL2main -lSDL2 -mwindows
