Re: [hatari-devel] OS X SDL2 fixes

Compiled with SDL2, Hatari crashs immediately at launch. None in my breakpoints are encountered.

See this piece of code from SDL_main.h in SDL2:

#elif defined(__IPHONEOS__)

/* On iOS SDL provides a main function that creates an application delegate

   and starts the iOS application run loop.

   See src/video/uikit/SDL_uikitappdelegate.m for more details.

*/

#define SDL_MAIN_NEEDED

#elif defined(__ANDROID__)

/* On Android SDL provides a Java class in SDLActivity.java that is the

   main activity entry point.

   See README-android.txt for more details on extending that class.

*/

#define SDL_MAIN_NEEDED

#endif

#endif /* SDL_MAIN_HANDLED */

#ifdef __cplusplus

#define C_LINKAGE   "C"

#else

#define C_LINKAGE

#endif /* __cplusplus */

/**

 *  \file SDL_main.h

*

 *  The application's main() function must be called with C linkage,

 *  and should be declared like this:

 *  \code

 *  #ifdef __cplusplus

 *  extern "C"

 *  #endif

 *  int main(int argc, char *argv[])

 *  {

 *  }

 *  \endcode

*/

#if defined(SDL_MAIN_NEEDED) || defined(SDL_MAIN_AVAILABLE)

#define main    SDL_main

#endif

As you can see macro SDL_MAIN_NEEDED is defined for IOS and not defined for OSx.

In SDL_main.h of SDL1 this macro is defined for IOS and OSx

This implies that compiled with SDL1 main function is called, but compiled with SDL2 main function is not called.

I change line #elif defined(__IPHONEOS__) by line #elif defined(__IPHONEOS__) || defined(__MACOSX__)

I compile SDL2 then compile Hatari. Now Hatari launchs then breakpoint in applicationDidFinishLaunching: function stop the launch process.

Following the launch process, I find that Hatari crashs during initialization of SDL. But I don’t know enough Hatari and SDL to continue!

Eero,

I am not a programmer anymore, but your explanation makes sense to me. I am assuming it is simply a difference between SDL1 and SDL2.
