Another SDL "Entry point must be defined" error.
Author
Okay, this error seems pretty common, so I've been searching for solutions for the past hour and none have helped.
I am using Visual C++ 2005 and SDL, and getting the error "LNK1561: entry point must be defined".
Now:
-I have linked against sdlmain.lib
-I am using a multi-threaded debug .dll for my C runtime
-I have tried both unicode and multibyte character sets
-I have made sure that I am using the proper version of the library (VC8)
-I have set up my project as a Win32 project, empty, with no precompiled headers
-I am about to slam my keyboard into my monitor.
So can anyone tell me what else there is to do?
You have to use the SDL_main instead of main or winmain or wethever
int SDL_main( int argc, char* args[] ){return 0;}

I have linked with sdl.lib and sdlmain.lib.
My main function looks like this:
int main(int, char**) { return 0; }
Edit: Using SDL_main doesn't fix the problem.

As a last resort, if you've downloaded the SDL source, you can try adding SDL_win32_main.c from the src/main/win32 directory to your project.

Wow, SiCrane, that worked perfectly! I'm not really sure why this is necessary though. Shouldn't SDL_Win32_main.o be linked in with sdlmain.lib? Why do I have to do this manually? Would the problem also be fixed if I built the source from scratch instead of downloading the precompiled VC8 library?

Yes, it should. (Well .obj and not .o, but you get the idea.)

I've no idea.

It's worth a shot. IIRC, the SDL people have released bum binary distributions before, but usually they fix it pretty quickly. Then again, I don't have any first hand experience with that; I always build the distribution from source and have never had any problems like this.
