SDL Video Init causes Exception on Mac OS X 10.8
- by ScrollerBlaster
I have just ported my C++ game to OS X and the first time it ran I get the following exception when trying to call SDL_SetVideoMode.

My init code looks like this:
if (SDL_Init(SDL_INIT_EVERYTHING) < 0)
return false;
const SDL_VideoInfo *videoInfo = SDL_GetVideoInfo();
if (!videoInfo) {
fprintf(stderr, "Video query failed: %s\n",
SDL_GetError());
return false;
}
/* the flags to pass to SDL_SetVideoMode */
videoFlags = SDL_OPENGL; /* Enable OpenGL in SDL */
videoFlags |= SDL_GL_DOUBLEBUFFER; /* Enable double buffering */
videoFlags |= SDL_HWPALETTE; /* Store the palette in hardware */
/* This checks to see if surfaces can be stored in memory */
if (videoInfo->hw_available)
videoFlags |= SDL_HWSURFACE;
else
videoFlags |= SDL_SWSURFACE;
if (w == 0) {
widthViewport = videoInfo->current_w;
heightViewport = videoInfo->current_h;
cout << "Will use full screen resolution of ";
videoFlags |= SDL_FULLSCREEN;
} else {
cout << "Will use full user supplied resolution of ";
widthViewport = w;
heightViewport = h;
videoFlags |= SDL_RESIZABLE; /* Enable window resizing */
}
cout << widthViewport << "x" << heightViewport << "\n";
/* This checks if hardware blits can be done */
if (videoInfo->blit_hw)
videoFlags |= SDL_HWACCEL;
/* Sets up OpenGL double buffering */
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
/* get a SDL surface */
surface = SDL_SetVideoMode(widthViewport, heightViewport,
SCREEN_BPP, videoFlags);
It gets into that last SDL call and throws the exception above. I have tried it in both full screen and resizable window mode, same thing.
I build my app old school, on the command line, as opposed to using Xcode.
