How to link to dynamic boost libs?

Question

I compiled boost lib and got these.

//Shared/dynamic link libraries

Answer 1

To configure boost use the user config header

<boost/config/user.hpp>

Then just look for the dynamic link lines and change to your desired configuration

// BOOST_ALL_DYN_LINK: Forces all libraries that have separate source, 
// to be linked as DLL's rather than static libraries on Microsoft Windows 
// (this macro is used to turn on __declspec(dllimport) modifiers, so that 
// the compiler knows which symbols to look for in a DLL rather than in a 
// static library).  Note that there may be some libraries that can only 
// be statically linked (Boost.Test for example) and others which may only 
// be dynamically linked (Boost.Threads for example), in these cases this 
// macro has no effect.
// #define BOOST_ALL_DYN_LINK

You can force Boost to use the DLLs by defining BOOST_ALL_DYN_LINK - either in your C++ preprocessor settings or by a #define in your stdafx.h pre-compiled header, e.g.:

#define BOOST_ALL_DYN_LINK

1. The .lib files are linked statically, while .dll files are linked dynamically. I believe it's a VC project setting.

The "lib" prefix is for static libraries. Use link=static 
The 's' letter is to static linking to runtime. Use runtime-link=static 
The 'd' is debug, use variant=debug 
The 'g' is using debug runtime, I think it's included in 'debug' variant 
already. If not runtime-debugging=on will help.
