Are you sure that you need to compile libs/detail/utf8_codecvt_facet.cpp?

boost/detail/utf8_codecvt_facet.hpp has this comment:
// Until the above points are fixed, a library which wants to use utf8 must:
// - include this header from one of it's headers or sources
// - include the corresponding .cpp file from one of the sources
// - before including either file, the library must define
//   - BOOST_UTF8_BEGIN_NAMESPACE to the namespace declaration that must be used
//   - BOOST_UTF8_END_NAMESPACE to the code to close the previous namespace
//   - declaration.
//   - BOOST_UTF8_DECL -- to the code which must be used for all 'exportable'
//     symbols.

from which it seems that the corresponding .cpp is not designed to be built directly, but via inclusion from another Boost lib.
