SDL won't init on Win32, under .NET

Kevin_Jenkins · May 29, 2004, 4:51am

This is my program:

#include “SDL.h” /* All SDL App’s need this */
#include <stdio.h>

int main() {

printf(“Initializing SDL.\n”);

/* Initialize defaults, Video and Audio */
if((SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO)==-1)) {
printf(“Could not initialize SDL: %s.\n”, SDL_GetError());
return -1;
}

printf(“SDL initialized.\n”);

printf(“Quiting SDL.\n”);

/* Shutdown all subsystems */
SDL_Quit();

printf(“Quiting…\n”);
return 0;
}

These are my errors:

msvcrt.lib(MSVCR71.dll) : error LNK2005: _exit already defined in
LIBCD.lib(crt0dat.obj)
msvcrt.lib(MSVCR71.dll) : error LNK2005: _strncpy already defined in

with use of other libs; use /NODEFAULTLIB:library
SDLmain.lib(SDL_win32_main.obj) : error LNK2019: unresolved external symbol

I’ve tried not importing LBCD and using /NODEFAULTLIB but those cause other
problems:

you should use

int main(int argc, char *argv[])

instead of

int main()
