Hi,

I am trying out boost thread libraries with VC 7.1 Here are my includes :

#define _MSC_VER 1310

#define BOOST_LIB_NAME "boost_thread"

#define BOOST_LIB_DIAGNOSTIC "on"// Show library file details.

#include <boost/config/auto_link.hpp>

#include <boost/thread/thread.hpp>

#include <iostream>

I am getting the following error :

c:\Boost\include\boost-1_31\boost\config\auto_link.hpp(269) : fatal error C1189: #error : "Mixing a dll boost library with a static runtime is a really bad idea..."

Looks like I am missing some #define.

You are not missing a #define, you have too many of them ;-). Seriously, you typically don't need to define anything before including a boost library. AFAICT, you neither need to include auto_link.hpp. You only include thread.hpp, which then does the rest automatically. The error you are getting is due to the fact that you are trying to link with a static C runtime, which does not work because thread itself is linked with a dynamic runtime. In MSVC you should use either /MDd or /MD and everything will work just fine. Regards, Andreas
