我正在努力找出问题出在哪里。
我是一个小组的成员，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（只是为了检查一切是否设置正确）时，我是唯一一个遇到分段错误的人。
以下是相关代码：
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);
...
}
当执行SDL_SetVideoMode(...)时，我遇到了分段错误。有什么线索可以解决这个问题吗？
我在Mac OS Mavericks上运行，并在终端编译。
Pingul % gcc-mp-4.8 -lstdc++ -std=c++11 -Wall -Wpedantic `sdl-config --cflags --libs` test_SDL.cc
如果可能的话，我的团队中其他人都使用Ubuntu。感谢所有帮助！
