Я пытаюсь SDL_DisplayFormat .png файл, я думаю, я могу пропустить зависимость

Это функция, которая дает мне дамп ошибки сегментации, это строка: 

optimizedImage = SDL_DisplayFormat( loadedImage );

Попытка построить это на Ubuntu Linux с использованием кодовых блоков для моей IDE.

I'mочень близки и хотят использовать возможности микшеров SDL, и было бы неплохо полностью настроить png.

Только что обнаруженная функция устарела.SDL_ConvertSurfaceFormat ();похоже, это замена и является частью sdl2 .. Но я получаю неопределенную ошибку, когда я пытаюсь это сделать .. sdl и sdl2 кажутся правильно связанными. 

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;
}

Вот мой файл cmakelists.text

Наконец-то ... снова попробовал звуковые библиотеки SDL для моего игрового движка .... и нашел способ пробиться !!!, хороший звук ... теперь ясно, как звонок, но я все еще думаю, что мне придется добавить библиотеки sdl_mixer должны быть удовлетворены. Но на этот раз я думаю, что смогу это сделать. Я нашел старый блог, который направил меня в правильном направлении. Я думаю, что я установил SDL, затем обновил до dev-библиотек, но это неправильный порядок, тогда я не мог правильно очистить старую библиотеку, но копал глубже и добавил инструменты для отслеживания и уничтожения файлов и символов, пока они не .. волшебство не произошло .. совершенно невероятно сложно сделать. Вот блог, который отправил мне правильный путь ->

"Если вы создали свой собственный SDL, у вас, вероятно, не было заголовков разработки для PulseAudio (или ALSA), поэтому он пытается использовать / dev / dsp, который не существуют во многих современных системах Linux (следовательно, SDL_Init (SDL_INIT_AUDIO) успешно, но при попытке открыть устройство не найдено). «APT-получить установить libasound2-dev libpulse-dev "и пересобрать SDL ... пусть настроить скрипт находит новые заголовки, поэтому включает поддержку PulseAudio и ALSA. «

...
