SDL_image 无法初始化：SDL_image 错误。 加载 libpng16-16:dll 失败：找不到指定的模块

Question

I have spent the last hour trying to find a fix for this error. I have searched all over SO and other sites for answers but nothing that I have found has worked so far. So here I am, in desperate need of help.

First of here are the versions of software and libraries that I am using:

• SDL2-2.0.12
• SDL2_image-2.0.5
• VS Community 2019

Here is my code for the area that messes up:

bool CApp::OnInit() {

if (SDL_Init(SDL_INIT_VIDEO) < 0) 
{
    printf("SDL could not initialize! SDL_Error: %s\n", SDL_GetError());
    return false;
}
else {

    std::cout << "SDL was initialized!!!" << std::endl;
}

// The window for the game.
Surf_Window = SDL_CreateWindow("SDL2 Window",
    SDL_WINDOWPOS_CENTERED,
    SDL_WINDOWPOS_CENTERED,
    screenWidth, screenHeight,
    0);

if (Surf_Window == NULL)
{
    return false;
}
else {

    std::cout << "Main Window was initialized!!!" << std::endl;
    //Initialize PNG loading
    int imgFlags = IMG_INIT_PNG;
    if (!(IMG_Init(imgFlags) & imgFlags))
    {
        printf("SDL_image could not initialize! SDL_image Error: %s\n", IMG_GetError());
        return false;
    }
    else
    {

        std::cout << "SDL_image was initialized!!!" << std::endl;
        //Get window surface
        Surf_Display = SDL_GetWindowSurface(Surf_Window);

        if (Surf_Display == NULL)
        {
            return false;
        }
    }
}

// Fill the window with White color.
SDL_FillRect(Surf_Display, NULL, SDL_MapRGB(Surf_Display->format, 0xFF, 0xFF, 0xFF));

// The image surface we load.
const char* image = "data/images/bgHomeScreen.bmp";
Surf_Test = CApp::OnLoad("data/images/bgHomeScreen.bmp");
//CSurface::OnLoad(Surf_Test, image);

if (Surf_Test == NULL) 
{
    printf("Unable to load image %s! SDL Error: %s\n", "data/images/bgHomeScreen.bmp", SDL_GetError());
    return false;
}

SDL_UpdateWindowSurface(Surf_Window);

SDL_Delay(2000);

return true;

}

I am looking to fix this error so that I can continue to learn the uses of SDL2.

Answer 1

I figured out the problem. I added all of the dependencies from the SDL2-2.0.12\lib\x86 to my projects Release and Debug directories and the program ran as expected. Just remember to copy the x64 folder instead of x86 if you plan on using 64 bit.
