I have ported everything now but there are some functions missing like:
SDL_main, SDL_malloc, SDL_free and so on. I replaced SDL_malloc and others with the corresponding functions from std but I don' ...

In SDLmain.m there are these lines:
/* Use this flag to determine whether we use SDLMain.nib or not */
#define SDL_USE_NIB_FILE 0

/* Use this flag to determine whether we use CPS (docking ...

When loading SDL, we already load Cocoa, why should we try to load it a second time?
Well, my point was that you actually don't load it a second time. No matter how many calls you make to dlopen (or ...

If SDL is already linked to Cocoa can't I use regular function declarations like this:
extern (C) char* registerName(char*);
Or do I still have to use "Derelict_GetProc", i ...

Actually, as SDL is linked to Cocoa, we can directly use the SDL SharedLib handle to get the function pointers. I think it's cleaner and it avoids an unnecessary dynamic load and handle management.
...

To load the Cocoa framework and get function pointers, you should do something like this:
import derelict.util.loader;

SharedLib cocoa = Derelict_LoadSharedLib("Cocoa.framework/Cocoa" ...

I could use a sample code to test with
Here is a simple test program.
import derelict.opengl.gl;
import derelict.util.exception;
import derelict.sdl.sdl;
import std.stdio;
import std.string;

Yes I think it's possible, you can do everything you can do in objc with the runtime functions I mentioned. It's a little tricky to create a new class that extends a objc class this way but it's possi ...

It’s funny that we have activity on this topic now. I didn't work on the problem since my last post until last week, where I played with SDLmain.m to try to be able to use it without the main() rede ...

Actually it should be @executable_path/../Frameworks to make it search in the Frameworks directory of the current application bundle.That's right, indeed (see [url=http://developer.apple.com/documenta ...

Calling dlopen multiple times on the same library isn't an issue. I just consulted the spec to be sure:

Only a single copy of an object file is brought into the address space, even if dlopen() is i ...

Indeed, the library paths for DerelictGLU for Mac OS X are empty. Actually, since the OpenGL framework contains libGLU.dylib, the GLU library is already loaded if the former is loaded and the GLU symb ...

DerelictGL now compiles correctly on Mac OS X. I fixed the DerelictGLContext-related issues in revision 288.

Regarding the SDL_main problem, an easy and clean solution hasn't been found yet, though ...

I was wondering about how to get rid of SDLmain.m and couldn't find an answer before finding your post. I didn't try your solution yet, but I'm confident knowing you succeeded to port your game.
