[Newbie] SDL 1.1.4 VS 1.1.6 with VC++5

SDL Development
1

Sorry to bother,
I’ve been using SDL 1.1.4 with VC++5 under Win98. Everything
worked fine. I upgraded to 1.1.6, and now I cannot compile any project
anymore. When I try to compile I get:

--------------------Configuration: new4 - Win32 Debug--------------------
Compiling…
main.cpp
Linking…
msvcrt.lib(MSVCRT.dll) : error LNK2005: _exit already defined in
LIBCMT.lib(crt0dat.obj)
msvcrt.lib(MSVCRT.dll) : error LNK2005: _strncpy already defined in
LIBCMT.lib(strncpy.obj)
msvcrt.lib(MSVCRT.dll) : error LNK2005: _fclose already defined in
LIBCMT.lib(fclose.obj)
LIBCMT.lib(crt0init.obj) : warning LNK4098: defaultlib "msvcrt.lib"
conflicts with use of other libs; use /NODEFAULTLIB:library
Debug/new4.exe : fatal error LNK1169: one or more multiply defined symbols
found
Error executing link.exe.

new4.exe - 4 error(s), 1 warning(s)

Using /NODEFAULTLIB:… does not change the situation.

The source here’s a very simple one (the one in Vc++.txt)

#include “SDL.h”

int main( int argc, char* argv[] )
{
// Body of the program goes here.
return 0;
}

Does anyone know what’s the matter? Thanks.__

Change your project settings to Debug Multithreaded in all
configurations and those errors should go away.

Unfortunately no. :frowning: I was using Debug Multithreaded in all
configurations also when working with 1.1.4.

Thanks anyway,__

Did you specifically try Multithreaded “DLL” (I’m sorry if I forgot to
mention that earlier), that error almost always indicated a conflict
between what SDL was built with and what your program was built with.

When changing to Debug Multithreaded DLL or Multithreaded DLL the
error becomes:

--------------------Configuration: foo - Win32 Debug--------------------
Compiling…
main.cpp
C:\Code\foo\main.cpp(11) : error C2561: ‘SDL_main’ : function must return a

Error executing cl.exe.

foo.exe - 1 error(s), 0 warning(s)

I always used Debug Multithreaded or Multithreaded with 1.1.4-, so
I wasn’t aware of the change. :slight_smile: Thanks.__

Well, i use a linker switch /FORCE:MULTIPLE (with Multithread static lib)
and it helps for me.
This of course is very ugly workaround, but it works.

I think SDL is pretty picky about what main is, is your main declared
like:

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

Even if you don’t use the command line arguments this is proper form.>

When changing to Debug Multithreaded DLL or Multithreaded DLL the
error becomes:

--------------------Configuration: foo - Win32 Debug--------------------
Compiling…
main.cpp
C:\Code\foo\main.cpp(11) : error C2561: ‘SDL_main’ : function must return a

value
Error executing cl.exe.

foo.exe - 1 error(s), 0 warning(s)

Ignore my other message, just put a return(0); at the end of main
somewhere.
