I don't know whether this is something that should be addressed here, or if it
should be addressed with
the maintainers of SDL.

Anyway, whenever I link libSDLmain.a to my D application, I all of a sudden
can't call the new operator
anymore.

Sample code (main.d):
------------------------------------------------
class Test {}

extern (C) int SDL_main(int argc,char** argv)
{
Test t = new Test();
return 0;
}
------------------------------------------------

build command:

% gdc -L/opt/local/lib -lSDLmain -lSDL main.d -framework Cocoa -o main

It builds fine, but when I run the main executable, I get a "Bus Error". If I comment out the line:

Test t = new Test();

and replace it with:

printf("Hello World!\n");

then when I run it I get the expected "Hello World!" output.

Normally I'd dig in to try and find out what's going on, but frankly I know
diddly squat when it comes to
Obj-C and Cocoa.

Probably both :-)

SDL uses a hack to replace the main function,
and their regular library doesn't work with D.

GLUT uses callbacks instead of playing with macros...

I have a working version for Mac OS X here:
http://www.algonet.se/~afb/d/

It has a patched SDLMain.m, with what you need...
(you build this obj-c code into a libSDLmain_d.a)


Make sure to (indirectly) call this the first thing:

int main(char[][] args)
{
	return SDL_InitApplication(args);
}

That helper above is in my "sdl" wrapper directory.

extern(C)
int SDL_main(int argc, char **argv)
{
	// here comes the real code
}

HTH,

Awesome! Thanks :)
