How to use SDL with OGRE?

Question

When I go to use OGRE with SDL (as described in this article), I seem to be having trouble with a second window that appears behind my main render window. Basically, the co

I see that you already solved your problem, but not all users will be content with downgrading SDL to 1.3. You can use SDL2 and an SDL2 window created via SDL_CreateWindow with OGRE. The code would look something like this:

if (SDL_Init(SDL_INIT_VIDEO) != 0) {
    OGRE_EXCEPT(Ogre::Exception::ERR_INTERNAL_ERROR, "Cannot initialize SDL2!",
        "BaseApplication::setup");
}

Ogre::Root *root = new Ogre::Root();
root->restoreConfig();
root->initialise(false);

Ogre::NameValuePairList params; // ogre window / render system params
SDL_Window *sdlWindow = SDL_CreateWindow("myWindow", posX, posY, width, height, vflags);
// see SDL_CreateWindow docs / examples for how to populate posX, posY, width, height, and vflags according to your needs

SDL_SysWMinfo wmInfo;
SDL_VERSION(&wmInfo.version);
if (SDL_GetWindowWMInfo(sdlWindow, &wmInfo) == SDL_FALSE) {
    OGRE_EXCEPT(Ogre::Exception::ERR_INTERNAL_ERROR,
        "Couldn't get WM Info! (SDL2)",
        "BaseApplication::setup");
}

params.insert(std::make_pair("macAPI", "cocoa"));
params.insert(std::make_pair("macAPICocoaUseNSView", "true"));

// grab a string representing the NSWindow pointer
Ogre::String winHandle = Ogre::StringConverter::toString((unsigned long)wmInfo.info.cocoa.window);

// assign the NSWindow pointer to the parentWindowHandle parameter
params.insert(std::make_pair("parentWindowHandle", winHandle));

Ogre::RenderWindow *ogreWindow = root->createRenderWindow("myWindowTitle", width, height, isFullscreen, ¶ms);
// see OGRE documentation on how to populate width, height, and isFullscreen to suit your needs

// create OGRE scene manager, camera, viewports, etc
