SDL linking error from hateez
Author
I recently tried to setup SDL, I got everything working except one thing. it keeps giving me this linking error,
SDLtest error LNK2019: unresolved external symbol __alloca_probe_16 referenced in function _main
wtf? this doesn't even have anything to do with the project. I looked all over the web for a fix and I couldn't find one, please help me. thanx :D
I don't use Visual Studio, but post the source and your linker options (the ones important to SDL anyway: libraries).
Try to cut back the source to the minimum amount of code required to generate the error.

I believe it has nothing to do with the libraries, but just this...
#include "SDL.h"
const int WINDOW_WIDTH = 640;
const int WINDOW_HEIGHT = 480;
const char* WINDOW_TITLE = "SDL Start";
int main(int argc, char **argv)
{
SDL_Init( SDL_INIT_VIDEO );
SDL_Surface* screen = SDL_SetVideoMode( WINDOW_WIDTH, WINDOW_HEIGHT, 0,
SDL_HWSURFACE | SDL_DOUBLEBUF );
SDL_WM_SetCaption( WINDOW_TITLE, 0 );
SDL_Quit();
return 0;
}
and actually I commented out everything besides the main part, and it even gives me another error then
SDLtest error LNK2005: _main already defined in main.obj
SDLtest error LNK2019: unresolved external symbol _SDL_main referenced in function _main
I have it on multi threaded dll
linking to these two libraries sdl.lib sdlmain.lib
im ignoring these two libraries msvcrt.lib libcmtd.lib
and I have the directories setup for both sdl/lib and sdl/include
#include "SDL.h"
const int WINDOW_WIDTH = 640;
const int WINDOW_HEIGHT = 480;
const char* WINDOW_TITLE = "SDL Start";
int main(int argc, char **argv)
{
SDL_Init( SDL_INIT_VIDEO );
SDL_Surface* screen = SDL_SetVideoMode( WINDOW_WIDTH, WINDOW_HEIGHT, 0,

SDL_WM_SetCaption( WINDOW_TITLE, 0 );

What do you mean you're ignoring them? I don't know what libcmtd.lib is, but msvcrt.lib looks suspiciously like what Microsoft would call its "common runtime" (ie the libc). Not linking it in is likely to cause problems.
I'm not a Windows developer BTW, and English isn't my native language. Sorry if I missed the point entirely.

Try using
int main(int argc, char *argv[])Make sure you've definitely got the libraries set up properly, and don't "ignore" the other two; msvcrt.lib is definitely an MS runtime and you'll most likely be wanting that.
You said you're using VS2003, so this might help. I personally use SDL under VS2005 but the setup procedure is very similar.
Good luck!
