a dumb question about SDL

okay, I'm having a problem with SDL that should be an easy one for anyone who uses it to solve -> I #include "SDL.h" at the beginning of my program, that works fine, but I wrote the following function

int initialize(void)
{
if(SDL_Init(SDL_INIT_VIDEO))
{
cout<<"Could not initialize SDL Video";
exit(1);
}
screen = SDL_SetVideoMode(1280,1024, 24, SDL_HWSURFACE|SDL_DOUBLEBUF|SDL_FULLSCREEN);
if ( screen == NULL ) {
fprintf(stderr, "Unable to set requested video mode: %s\n", SDL_GetError());
exit(1);
}
return 0;
}

which is mostly code from the SDL site...it compiles fine, but I get the following linker errors...

MAIN.OBJ : error LNK2001: unresolved external symbol _SDL_GetError
MAIN.OBJ : error LNK2001: unresolved external symbol _SDL_SetVideoMode
MAIN.OBJ : error LNK2001: unresolved external symbol _SDL_Init
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
Debug/3D Engine.exe : fatal error LNK1120: 5 unresolved externals

What's wrong with it? Did I do something stupid and easily fixed (I hope)?

at a guess i'd say you havent included the library files.

Yes, those are a result of missing .lib files. If you're in Windows you'll need SDLmain.lib and SDL.lib.
With VC++ go to the project -> settings -> link tab and add those to the project/object modules line.

Using Dev-C++ go to the project options, additional compiler options and add:
-lmingw32 -lSDLmain -lSDL

if you are using Visual C++, make sure to change the settings to Multithreaded DLL. That must be there to compile.

hmmm...I included the libraries that tgm told me to include, (btw, I'm using VC++), and I think I did what davidp was trying to tell me to do, but I haven't figured out where to put sdl.dll or even if that's what I need...I'm now getting these linker errors...

nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
Debug/3D Engine.exe : fatal error LNK1120: 2 unresolved externals

I'd consult the documentation on VC++, but I don't have any (; Thanks for the help...

okay, guys, I declare myself an idiot...getting it to work was pretty easy after I found this online...so if anyone else out there is having any trouble with this ever, send 'em this link (:
