SDL2-image won't load textures (but surfaces work) and i don't get any error message

Question

i am making a game using SDL2, using IMG_LoadTexture() to load images, and it works fine on my main computer, but i recently acquired a new laptop, and the same code on this new machine won't load textures, but SDL doesn't give me any error message.

• IMG_LoadTexture() returns null
• IMG_GetError() and SDL_GetError() give me nothing (which is weird, since IMG_LoadTexture() returning null means an error occured)
• Loading surfaces (IMG_Load()) works
• I work on msys2/mingw64 and launch the executable from the MSYS2/MINGW64 shell, checked for zlip and libpng, everything is here
• Checked SDL initialization, SDL_Init(SDL_INIT_VIDEO | SDL_INIT_JOYSTICK) returns 0 (no error), IMG_Init(IMG_INIT_PNG | IMG_INIT_JPG) returns 3 (no error), same outputs as on the other computer where everything works.
• Happens with all tested image formats (png, jpg, bmp)

does anyone have any idea about what could be the cause of such a situation ? In the mingw install or something ?

Reproducing this

Here are the steps that led to the situation :

• Install msys from the official website

• install the following libraries using pacman :

  • base
  • make
  • mingw-w64-x86_64-gcc
  • mingw-w64-x86_64-SDL2
  • mingw-w64-x86_64-SDL2_image

• Compile the following program :

  #include "SDL2/SDL.h"
  #include "SDL2/SDL_image.h"
  #include "SDL2/SDL_syswm.h"
  #include <iostream>    
  int main(int argc, char** argv){
  
      int res = SDL_Init(SDL_INIT_VIDEO | SDL_INIT_JOYSTICK);
  
      std::cout << res << '\n';
      if ( res < 0){
          printf("Couldn't initialize SDL (%d): %s\n", res, SDL_GetError());
          exit(1);
      }
  
      res = IMG_Init(IMG_INIT_PNG | IMG_INIT_JPG);
  
      std::cout << res << '\n';
      if (res < 0) {
          printf("Couldn't initialize SDL Image (%d): %s\n", res, IMG_GetError());
          exit(1);    
      };
  
      int rendererFlags = SDL_RENDERER_ACCELERATED;
      int windowFlags = 0;
  
      SDL_Window* window = SDL_CreateWindow("KuriX", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 800, 600, windowFlags);
  
      if (!window){
          printf("Failed to open %d x %d window: %s\n", 800, 600, SDL_GetError());
          exit(1);
      }
  
      SDL_SysWMinfo win_info;
  
      SDL_VERSION(&win_info.version);
      SDL_GetWindowWMInfo(window, &win_info);
  
      SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear");
  
      SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, rendererFlags);
  
      if (!renderer){
          printf("Failed to create renderer: %s\n", SDL_GetError());
          exit(1);
      }
  
      SDL_Texture* t = IMG_LoadTexture(renderer, "JPGTest.jpg");
      std::cout << t << '\n';
  
      if (t == NULL){
          std::cerr << "Error ! Message : " << IMG_GetError() << '\n';
      }
  
      return 0;
  }
  

• compile/link with

  g++ testSDL.cpp -o out.exe `sdl2-config --cflags --static-libs` -Wall -g -std=gnu++2a -static-libgcc -static-libstdc++ -lSDL2_image -lm
  

  Output :

  0
  3 
  0
  Error ! Message :
  

Keep in mind that the same code, using the same libraries, works fine on my main computer, and all previous computers i used previously. Something must have went wrong with the installation on the new laptop, but i just don't see what.
