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 none 的解决方案在我链接到 SDL 时有效，这是我的代码：

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

int main()
{
    return 0;
}

我使用命令行 g++ 继承了命令：

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

我正在使用 -v:

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驱动器已满并且 visual studio 至少是 4GB 2. 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
