我想 SDL_DisplayFormat 一个 .png 文件，我想，我可能缺少一个依赖项
I'm trying to SDL_DisplayFormat a .png file, I think, I may be missing a dependency
这是给我分段错误转储的函数，
这是行：
optimizedImage = SDL_DisplayFormat( loadedImage );
尝试在 ubuntu Linux 上为我的 IDE 使用代码块构建它。
我非常想使用 SDL 混音器功能，并且 png 也可以完全设置。
刚刚发现该功能可能已被弃用。 SDL_ConvertSurfaceFormat();似乎是替代品并且是 sdl2 的一部分。但是我在尝试时遇到未定义的错误。sdl 和 sdl2 似乎链接正确。
SDL_Surface *load_image( std::string filename )
{
//The image that's loaded
cout<< "entered load image files"<< endl;
SDL_Surface* loadedImage = NULL;
//The optimized surface that will be used
SDL_Surface* optimizedImage = NULL;
//Load the image
loadedImage = IMG_Load( filename.c_str() );
cout<< "image image should be set"<< endl;
//If the image loaded
if( loadedImage != NULL )
{
cout<< "loaded image isn't null, hooray!"<< endl;
//Create an optimized surface
optimizedImage = SDL_DisplayFormat( loadedImage );
cout<< "optimized image should be in display format now"<< endl;
//Free the old surface
SDL_FreeSurface( loadedImage );
cout<< "sdl surface is free"<< endl;
//If the surface was optimized
if( optimizedImage != NULL )
{cout<< "optimized image is not null"<< endl;
//Color key surface
SDL_SetColorKey( optimizedImage, SDL_SRCCOLORKEY, SDL_MapRGB( optimizedImage->format, 0, 0xFF, 0xFF ) );
cout<< "sdl setcolor key is ok"<< endl;
}
}
//Return the optimized surface
return optimizedImage;
}
这是我的 cmakelists.text 文件

终于......再次为我的 game-engine 尝试了 SDL 声音库......并找到了解决方法！！！，好声音......现在很清楚，但我仍然认为我必须添加 sdl_mixer 个库才能满足。但是这次我觉得我可以做到。我找到了一个旧博客，它让我朝着正确的方向前进。我想我安装了 SDL，然后升级到开发库，但顺序错误，然后我无法正确清除旧库，但更深入地挖掘并添加了工具来跟踪、销毁和优化文件和符号，直到……魔法发生了……完全难以置信地难以做到。这是向我发送正确方式的博客->
“如果您构建了自己的 SDL，您可能没有进行开发 headers
对于 PulseAudio（或 ALSA），因此它尝试使用 /dev/dsp，但它不
存在于许多现代 Linux 系统中（因此，SDL_Init(SDL_INIT_AUDIO)
成功，但当您尝试打开设备时未找到任何设备）。 “apt-get
安装 libasound2-dev libpulse-dev" 并重建 SDL...让配置
脚本找到新的 headers，因此它包括 PulseAudio 和 ALSA 支持。 “
这是给我分段错误转储的函数， 这是行：
optimizedImage = SDL_DisplayFormat( loadedImage );
尝试在 ubuntu Linux 上为我的 IDE 使用代码块构建它。
我非常想使用 SDL 混音器功能，并且 png 也可以完全设置。
刚刚发现该功能可能已被弃用。 SDL_ConvertSurfaceFormat();似乎是替代品并且是 sdl2 的一部分。但是我在尝试时遇到未定义的错误。sdl 和 sdl2 似乎链接正确。

终于......再次为我的 game-engine 尝试了 SDL 声音库......并找到了解决方法！！！，好声音......现在很清楚，但我仍然认为我必须添加 sdl_mixer 个库才能满足。但是这次我觉得我可以做到。我找到了一个旧博客，它让我朝着正确的方向前进。我想我安装了 SDL，然后升级到开发库，但顺序错误，然后我无法正确清除旧库，但更深入地挖掘并添加了工具来跟踪、销毁和优化文件和符号，直到……魔法发生了……完全难以置信地难以做到。这是向我发送正确方式的博客->
“如果您构建了自己的 SDL，您可能没有进行开发 headers 对于 PulseAudio（或 ALSA），因此它尝试使用 /dev/dsp，但它不 存在于许多现代 Linux 系统中（因此，SDL_Init(SDL_INIT_AUDIO) 成功，但当您尝试打开设备时未找到任何设备）。 “apt-get 安装 libasound2-dev libpulse-dev" 并重建 SDL...让配置 脚本找到新的 headers，因此它包括 PulseAudio 和 ALSA 支持。 “
