SDL does indeed change the name of main() in it's definitions for Mac
OS X
and Windows. If you did the normal SDL framework install then there
should
be a new option when you create a new project for an "SDL
Application". You
must keep the two files that SDL includes in there ( SDLmain.h and
SDLmain.m
I think ). You must also link to the Cocoa framework as these are Cocoa
files. SDLmain.m initializes SDL and such and then calls your main
functions
( which it redefined in the header file. )
Hope that helps,

oke, as i mentoied in the subject `ld` will always
close with `ld failed, undefined symbol _main`, but
a main does 200% exist (i'm a newbee but not such a
newbee). This problem is only if i'm using the SDL-Framework.
Finally on a Linux-Mac with gcc3 it will works perfectly...
Do I need gcc3 or does SDL have some bugs ?
Somewhere in the SDL headers there's a "#define main SDLmain" (or
something similar). The problem is that the SDL lib doesn't include any
main itself (which would call SDLmain), or that main doesn't work
somehow, I can't remember right now.
I didn't get it to work myself, and I wouldn't call me a newbie at all.
On the other hand, I didn't really play around more than one or two
hours.
