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

问题描述

我花了最后一个小时来尝试解决错误。我已经在SO和其他站点的各处搜索了答案,但是到目前为止,我所发现的任何方法都无效。所以在这里,我迫切需要帮助。

首先是我正在使用的软件和库的版本:

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

这是我弄乱区域的代码

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,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));

// 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;

}

我正在寻求解决错误,以便我可以继续学习SDL2的用法

解决方法

我发现了问题所在。我将SDL2-2.0.12\lib\x86的所有依赖项添加到我的项目的Release和Debug目录中,程序按预期运行。如果计划使用64位,请记住要复制x64文件夹而不是x86。
