Re: Problem with MFC application that uses win32.dll file

I included winsock header and I compiled it without any problems. New
problems appear when I create object from win32.dll library in MFC
application. win32.dll is built by using Multithreaded debug DLL run-time
library. I got console output:

MSVCRT.lib(MSVCRT.dll) : error LNK2005: _malloc already defined in
libcmt.lib(malloc.obj)
MSVCRT.lib(MSVCRT.dll) : error LNK2005: _free already defined in

MSVCRT.lib(MSVCRT.dll) : error LNK2005: _strncmp already defined in
libcmt.lib(strncmp.obj)...

and so on. If I change run-time library in MFC application to
Multithreaded
debug DLL I got errors:

libcmt.lib(crt0dat.obj) : error LNK2005: _exit already defined in
msvcrt.lib(MSVCRT.dll)

msvcrt.lib(MSVCRT.dll)
libcmt.lib(strcat.obj) : error LNK2005: _strcpy already defined in
msvcrt.lib(MSVCRT.dll)

How I can solve these problems?
