 |

Hi,
I'm working on porting bochs, but I'm running across a problem when it comes to building with SDL. My error is as follows
Error

make: *** [bochs] Error 1
|
I have an SDL_main in my source (I've tried main and SDL_main, both with extern "C" but neither fixed the problem). I also include SDL.h
I believe it may be a problem with my makefile (seen below). I've had a look and tried many things to rectify the problem but nothing I have tried seems to have worked.
Any help at all will be appreciated.

try changing int main() by int SDL_main()
Be carrefull SDL_main is case sensitive |

Thanks, but it wasn't that. I realised that i hadn't actually initialised SDL. Thanks anyway! All works now.
For anyone else interested, i added an initialization statement at the top of my SDL_main()
| Code: |
if (SDL_Init (SDL_INIT_VIDEO|SDL_INIT_AUDIO|SDL_INIT_JOYSTICK) < 0)
{
}
else
{
}
