I am trying to create a project in the C89 language using the SDL2 library. I am using MinGW and have verified the correct installation of SDL2 using the 64-bit version. The code for the small experiment I am doing is:

#include <SDL2/SDL.h>
#include <stdio.h>

int main(int argc, char* argv[]) {
// Initialize SDL
if (SDL_Init(SDL_INIT_VIDEO) != 0) {
printf("SDL initialization error: %s\n", SDL_GetError());
return 1;
}

// Create a window
SDL_Window* window = SDL_CreateWindow(
"SDL2 Window",
SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
640, 480,
SDL_WINDOW_SHOWN
);

if (window == NULL) {
printf("Window creation error: %s\n", SDL_GetError());
SDL_Quit();
return 1;
}

// Event handling
SDL_Event event;
int running = 1;
while (running) {
while (SDL_PollEvent(&event)) {
if (event.type == SDL_QUIT) {
running = 0;
}
}
SDL_Delay(16); // To limit CPU usage
}

// Clean up and close SDL
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}

The errors I am getting are:

Could you please help me resolve this issue?
I am completely ignorant in the use of SDL2. Thank you in advance to anyone who can help me!
