The reason is: #include <boost/filesystem.hpp> --> includes <boost/path.hpp> --> includes <boost/system/system_error.hpp> --> includes <boost/system/error_code.hpp>
File boost/system/error_code.hpp has following declarations:
BOOST_SYSTEM_DECL const error_category & get_system_category(); BOOST_SYSTEM_DECL const error_category & get_generic_category();
So, when the header above is included in main.cpp, BOOST_SYSTEM_DECL unrolls to: __declspec(dllimport). And this causes the linker error.
As a result, library that links boost::filesystem should link boost::system.
Yes, and this:
lib boost_filesystem : $(SOURCES).cpp ../../system/build//boost_system :
should be enough for that. I'll check why is that not working.
I've looked. Apparently, Boost.Filesystem not only uses Boost.System in its sources, but also uses it in inlined and/or template functions. Therefore, a client of Boost.Filesystem will have direct references to Boost.System function in it. And on Windows, for this to work, Boost.System library must be directly linked with. I've checked in a patch that adds necessary usage requirements to Boost.Filesystem, see: https://svn.boost.org/trac/boost/changeset/58028 Thanks for the report! - Volodya
