Does SDL can work with VC7?

SDL Development

I created a simple SDL application on vs2003.net, Whatever I use sdL VC6 or VC8, when linked the application, it will generate error LNK2019: unresolved external symbol _main referenced in function _mainCRTStartup.

Does SDL can work with VC7 ?How can it do?

Hi,

I think this is your problem:
http://www.libsdl.org/faq.php?action=listentries&category=7#55

Try linking with SDLmain.

You have a normal main function in your code?

Yep, except for SDL 1.2 with Visual C++ it’s SDLmain.libOn Mon, Sep 28, 2009 at 8:29 AM, Christoph Nelles wrote:

When I did it according to the suggestion mentioned in http://www.libsdl.org/faq.php?action=listentries&category=7#55.

I generate another Link error as below:

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

How it happened ?

This is a C library mismatch. Make sure all projects you link to are
using the same C runtime library. (It’s listed under Code Generation
in the project properties)On Mon, Sep 28, 2009 at 8:47 PM, kundi <jiangjkd at 163.com> wrote:
