调用SDL_SetVideoMode时出现分段错误

我是一个组的一部分，我们正在使用SDL进行图形处理。当我运行我们的test_SDL.cc程序（只是为了查看所有设置正确）时，我是唯一一个出现分段错误的人。

下面是相关代码：

int main(int argc, char** arg) 
{ 
    // Initializing 
    if(-1 == SDL_Init(SDL_INIT_EVERYTHING)) 
     return 1; 

    SDL_Surface* screen{nullptr}; 
    SDL_Surface* hello{nullptr}; 

    screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); 
    ... 
}

当SDL_SetVideoMode（...）执行我得到的分割故障。任何可能的线索？

我在Mac OS上运行的小牛队，并与终端

Pingul % gcc-mp-4.8 -lstdc++ -std=c++11 -Wall -Wpedantic `sdl-config --cflags --libs` test_SDL.cc

编译如果它可以有所作为的其他所有在我的组使用的Ubuntu。感谢所有帮助！

你/你的小组成员正在使用什么版本的sdl？ – user1810087

@itwasntpete我们正在使用1.2.15。在您的建议后，我尝试将32更改为24，并查看所有可用选项。唯一的工作是SDL_FULLSCREEN，所有其他也导致了分段错误。你有洞察力为什么？如果没有，我会用我得到的，但会很有趣，否则以及:) – pingul

你试过[SDL_GetVideoInfo（）]（http://www.libsdl.org/release/SDL-1.2。 15/docs/html/sdlvideoinfo.html）看看“可能”最好？另外，请发布一些错误。 – user1810087

修复每像素位并不是一个好主意。也不是每个mac-os都支持sdl上的32位。尝试一些其他的价值。 0用于自动分配，它通常不在mac上运行。我认为24应该这样做。

screen = SDL_SetVideoMode(640, 480, 24, SDL_SWSURFACE);

您还可以使用SDL_GetVideoInfo();来确定您应该使用哪种模式。
