Hi all,
I?ve found an error in my program when I?ve tried to link my program. I?ve
configured my environment (VC++ 7.1) as multithreaded DLL and linked the
correct libraries. I?ve started a new project (Win32 program) and I?ve
inserted the following simple code:
#include
#include
#include “sdl.h”
int main( int argc, char *argv[] ){
printf( “>Iniciando SDL…\n” );
if( SDL_Init( SDL_INIT_VIDEO ) < 0 ) {
printf( “Error al iniciar SDL.\n” );
return -1;
}
printf( “>SDL Iniciado.\n” );
printf( ">Creando ventana.\n" );
if( SDL_SetVideoMode( 400, 400, 16, 0 ) == NULL ) {
printf( "Error al setear modo de video: %s\n",
SDL_GetError() );
SDL_Quit();
return -1;
}
SDL_WM_SetCaption( "Hola mundo!", "Hola Mundo!" );
SDL_Delay( 5000 );
printf( ">Cerrando SDL ...\n" );
SDL_Quit();
printf( ">SDL Terminado.\n" );
return 0;
}
The linker always says that exit() is always defined. There are other ways
to link SDL libs, different than the documentation? It exists a trick to
solve this problem?
Note: If I delete #include then exit() symbol is not found.
Thanks in advance!

What happens if you #include the normal CRT headers instead of the STL
ones? (i.e. #include <stdio.h> and #include <stdlib.h> instead)
The linker always says that exit() is always defined.
What’s the linker error message exactly?–

Hi Rasmus,
Error message always is:
msvcrt.lib(MSVCR71.dll) : error LNK2005: _exit already defined in
LIBCD.lib(crt0dat.obj)
msvcrt.lib(MSVCR71.dll) : error LNK2005: _strncpy already defined in
LIBCD.lib(strncpy.obj)
msvcrt.lib(MSVCR71.dll) : error LNK2005: _fclose already defined in
LIBCD.lib(fclose.obj)
msvcrt.lib(MSVCR71.dll) : error LNK2005: __isctype already defined in
LIBCD.lib(isctype.obj)
Finished searching libraries
LIBCD.lib(crt0init.obj) : warning LNK4098: defaultlib ‘msvcrt.lib’ conflicts
with use of other libs; use /NODEFAULTLIB:library
Debug/Prueba_SDL_and_OpenGL.exe : fatal error LNK1169: one or more multiply
defined symbols found
Even if I include stdio.h and stdlib.h.
My solution at this moment is to force link the libraries, but I guess that
other way is possible.
Thanks

It seems that you are mixing up debug and release libraries in some way.
Under “Code generation” configuration, have you selected
"Multithreaded DLL" or “Multithreaded Debug DLL”? (can’t remember the
exact names)
You need to select the debug one.On 5/10/06, Ferran Ferri wrote:
