'Can't run SDL2 project, "Cannot execute "": %1 Not a valid Win32-application"

I'm trying to teach myself how to use SDL2 with Qt Creator but keep getting into these "just let me code" situations. Currently, I'm just trying to open a window with a green picture on it (doing a tutorial) but I get this error:

Cannot execute "": %1 not a valid Win32-application

I'm using MinGw 5.3.0 32bit2 as the compiler and I've managed to run other projects without this error. I tried tinkering with the Build and Run configurations, but haven't had any luck. Currently my (essential) Run configurations look like this:

Executable C:\...\sdl_test\debug\sdl_test.exe
Working directory: C:\...\sdl_test

Also for reference, here's main.cpp:

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

using namespace std;



int main()
{
    bool quit = false;
    SDL_Init(SDL_INIT_VIDEO);
    SDL_Window* window = nullptr;
    window = SDL_CreateWindow("MVP", 100, 100, 600, 400,
                              SDL_WINDOW_SHOWN);

    if(window == nullptr){
        cout << "Window could not be created." << endl;
        return 0;
    }

    SDL_Renderer* renderer = nullptr;
    renderer = SDL_CreateRenderer(window, -1,
                                  SDL_RENDERER_ACCELERATED);
    SDL_Event* mainEvent = new SDL_Event();

    SDL_Texture* grass_image = NULL;
    grass_image = IMG_LoadTexture(renderer, "grass.bmp");

    SDL_Rect grass_rect;
    grass_rect.x = 10;
    grass_rect.y = 50;
    grass_rect.w = 250;
    grass_rect.h = 250;

    while(!quit && mainEvent->type != SDL_QUIT){
        SDL_PollEvent(mainEvent);
        SDL_RenderClear(renderer);

        SDL_RenderCopy(renderer, grass_image, NULL, &grass_rect);

        SDL_RenderPresent(renderer);
    }
    SDL_DestroyWindow(window);
    SDL_DestroyRenderer(renderer);
    delete mainEvent;

    return 0;

}

Feeling hopeless, since I just want to open a window with a green rectangle on it... is that too much to ask?!

The code you are showing to us works for Linux and any sane system :)

There could be a few issues for your problem:

1 - you are trying to run a 64 bit application in a 32 bit system

2 - your dll's could be corrupt

3 - your SDL dll's could be compiled with Microsoft Visual Studio (and you would need to get dll's generated with MinGW)

also, you should pass a few flags to the compiler, since you told us that you are using Qt Creator, possibly you have a projectname.pro file or a CMakeLists.txt

discover what you have, and pass those flags to the compiler:

-Wl,-subsystem,windows

and link against those libraries

-lmingw32 -lSDL2main -lSDL2
