Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

#ifdef BOOST_HAS_DECLSPEC // defined in config system
// we need to import/export our code only if the user has specifically
// asked for it by defining either BOOST_ALL_DYN_LINK if they want all boost
// libraries to be dynamically linked, or BOOST_FILESYSTEM_DYN_LINK
// if they want just this one to be dynamically liked:
#if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_FILESYSTEM_DYN_LINK)
// export if this is our own source, otherwise import:
#ifdef BOOST_FILESYSTEM_SOURCE
# define BOOST_FILESYSTEM_DECL __declspec(dllexport)
#else
# define BOOST_FILESYSTEM_DECL __declspec(dllimport)
#endif  // BOOST_FILESYSTEM_SOURCE

// if BOOST_FILESYSTEM_DECL isn't defined yet define it now:

//  enable automatic library variant selection  ------------------------------//

// Set the name of our library, this will get undef'ed by auto_link.hpp
// once it's done with it:
//
#define BOOST_LIB_NAME boost_filesystem
//
// If we're importing code from a dll, then tell auto_link.hpp about it:
//
#if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_FILESYSTEM_DYN_LINK)
#  define BOOST_DYN_LINK

//
// And include the header that does the work:
//
#include <boost/config/auto_link.hpp>
#endif  // auto-linking disabled

#endif // BOOST_FILESYSTEM_CONFIG_HPP
