Trying to setup SDL on Windows(VSCode/MinGW)

SDL Development
1

I am trying to setup SDL Library on a Windows Platform with VSCode. I used the official SDL Page to download SDL 2.0.12. I have followed Lazyfoo’s Tutorial to set up with MinGW. Here’s what I’ve done :

  • Created a “mingw_dev_lib” Folder in my C drive

  • Extracted the contents of “i686-w64-mingw32” into “mingw_dev_lib”.

  • Then made a Source file for testing setup

    #include <iostream>

#include <SDL2/SDL.h>

int main(int argc, char * argv[])
{
    // Initialize SDL with video
    SDL_Init(SDL_INIT_VIDEO);

    // Create a window with SDL
    if(SDL_SetVideoMode(640, 480, 32, SDL_DOUBLEBUF | SDL_OPENGL) == 0)
    {
        std::cerr << "Failed to set video mode\n";
        return 1;
    }


    SDL_Event event;     // used to store any events from the OS
    bool running = true; // used to determine if we're running the game
        while(running)
        {
            // poll for events from SDL
            while(SDL_PollEvent(&event))
            {
                // determine if the user still wants to have the window open
                // (this basically checks if the user has pressed 'X')
                running = event.type != SDL_QUIT;
            }

            // Swap OpenGL buffers
            SDL_GL_SwapBuffers();
        }

        // Quit SDL
        SDL_Quit();

        return 0;
    }

I use this command in my terminal:

g++ 01_hello_SDL.cpp -IC:\mingw_dev_lib\include\SDL2 -LC:\mingw_dev_lib\lib -w -Wl,-subsystem,windows -lmingw32 -lSDL2main -lSDL2 -o 01_hello_SDL

Your configuration seems to be correct, the only problem is that you’re using SDL1 functions, like SDL_SetVideoMode and SDL_GL_SwapBuffers. Here you can find some tutorials to SDL2. Also, since your include folder is the SDL2 folder -IC:\mingw_dev_lib\include\SDL2, you can just put #include <SDL.h> instead of #include <SDL2/SDL.h>. Or, if you wish you can download SDL1, but you will have to change the command.

Thank You This helped!! :blush:
