While trying to build the SDLMain.m included with SDL 1.2.14, with
#define SDL_USE_NIB_FILE 1:
/Users/steven/Development/darwinia/targets/macosx/Darwinia/SDLMain.m:

I don't have time today to look at this in detail, but the problem is definitely the poseAsClass: method.
This was deprecated in Obj-C 2.0 and not retained in 64-bit.
I've never used this method and it has always been limited to esoteric uses. I think this is why Apple wanted to dump it (among complicating some other things they do). I have read about others getting bit by this when migrating. Long story short, there really isn't a migration path for this method. The question that then must be asked is why are we using it (what does it accomplish), and then figure out the 'proper' way of accomplishing that.
Glancing at SDLMain.m, it's not obvious to me why it is there or what it is really accomplishing. My only speculation is that NSApplicationMain hardcodes something to look for NSApplication and a subclass (SDLApplication) fails for some reason (assuming that the original coder did this for good reason).
Three thoughts come to mind.
1) The Info.plist has properties to control things related to the startup class and nib.
NSPrincipalClass, NSMainNibFile
Maybe principle class needs to be SDLApplication and we can delete the poseAs
2) I was told that 10.6 introduced new APIs to make programatic NIB wrangling and avoidance easier. Unfortunately, I don't know the specifics.
3) Instead of subclassing NSApplication in SDLMain.m, maybe we can just add a category. It looks like the following is the only thing that is done (quick glance):
@interface SDLApplication : NSApplication
@end
@implementation SDLApplication
/* Invoked from the Quit menu item */
- (void)terminate:(id)sender
{
/* Post a SDL_QUIT event */
SDL_Event event;
event.type = SDL_QUIT;
SDL_PushEvent(&event);
}
@end
So instead, we change this to: (warning written in mail and untested)
@interface NSApplication (SDLApplication)
- (void) terminate:(id)sender;
@end
@implementation NSApplication (SDLApplication)
/* Invoked from the Quit menu item */
- (void)terminate:(id)sender
{
/* Post a SDL_QUIT event */
SDL_Event event;
event.type = SDL_QUIT;
SDL_PushEvent(&event);
}
@end
Then everywhere SDLApplication is used, we change it to NSApplication (and remove the poseAsClass line).
Perhaps you could ask the bug reporter to try this solution (#3).
And if that fails, maybe try #1.

The suggested change (diff below) seems to work fine.

Project files for embedded Visual C++ 3.0, 4.0 and Visual Studio 2005 can be found in VisualCE.zip SDL supports GAPI and WinDib output for Windows CE. GAPI driver supports: - all possible WinCE devices (Pocket PC, Smartphones, HPC) with different orientations of video memory and resolutions. - 4, 8 and 16 bpp devices - special handling of 8bpp on 8bpp devices - VGA mode, you can even switch between VGA and GAPI in runtime (between 240x320 and 480x640 for example). On VGA devices you can use either GAPI or VGA. - Landscape mode and automatic rotation of buttons and stylus coordinates. To enable landscape mode make width of video screen bigger than height. For example: SDL_SetVideoMode(320,240,16,SDL_FULLSCREEN) - WM2005 - SDL_ListModes NOTE: There are several SDL features not available in the WinCE port of SDL. - DirectX is not yet available - Semaphores are not available - Joystick support is not available - CD-ROM control is not available In addition, there are several features that run in "degraded" mode: Preprocessor Symbol Effect =================== ================================= SDL_systimer.c: USE_GETTICKCOUNT Less accurate values for SDL time functions USE_SETTIMER Use only a single marginally accurate timer SDL_syswm.c: DISABLE_ICON_SUPPORT Can't set the runtime window icon SDL_sysmouse.c: USE_STATIC_CURSOR Only the arrow cursor is available SDL_sysevents.c: NO_GETKEYBOARDSTATE Can't get modifier state on keyboard focus SDL_dibevents.c: NO_GETKEYBOARDSTATE Very limited keycode translation SDL_dibvideo.c: NO_GETDIBITS Can't distinguish between 15 bpp and 16 bpp NO_CHANGEDISPLAYSETTINGS No fullscreen support NO_GAMMA_SUPPORT Gamma correction not available
