Hi Volodya, the fix for #6797 in 4ae33ce15e5b6345e6eefa19466fdf7cd28a7bbd breaks compilation if Boost.ProgramOptions on msvc-11.0 and -12.0. See full error log with msvc-11.0 attached. It seems that the export macros changes the template evaluation somehow, so msvc now needs "decrement" and "advance" member. The short error is: E:\dev\devel\boost\boost/iterator/iterator_facade.hpp(402) : error C2039: 'decrement' : is not a member of 'boost::program_options::detail::common_config_file_iterator' E:\dev\devel\boost\boost/iterator/iterator_facade.hpp(420) : error C2039: 'advance' : is not a member of 'boost::program_options::detail::common_config_file_iterator' I'm not sure how to implement at least empty stubs or if this can be otherwise worked around.
