Compiling Errors, i.e., error: use of deleted function 'boost::filesystem3::.....

[John-Lu95]

Hi, When I try to compile with 'scons', I meet errors. The below is part of compiling error information: .... .... /usr/local/include/boost/type_traits/is_convertible.hpp:135:75: error: use of deleted function 'boost::filesystem3::directory_iterator::directory_iterator(const boost::filesystem3::directory_iterator&)' static bool const value = sizeof( boost::detail::checker<To>::_m_check(_m_from, 0) ) .... .... /usr/local/include/boost/filesystem/v3/operations.hpp:581:9: error: use of deleted function 'boost::shared_ptrboost::filesystem3::detail::dir_itr_imp::shared_ptr(const boost::shared_ptrboost::filesystem3::detail::dir_itr_imp&)' ... ... /usr/include/c++/5/ext/new_allocator.h:120:4: error: use of deleted function 'boost::filesystem3::directory_iterator::directory_iterator(const boost::filesystem3::directory_iterator&)' { ::new((void )__p) _Up(std::forward<_Args>(__args)...); } .... .... /usr/include/c++/5/bits/stl_construct.h:75:7: error: use of deleted function 'boost::filesystem3::directory_iterator::directory_iterator(const boost::filesystem3::directory_iterator&)' { ::new(static_cast<void>(__p)) _T1(std::forward<_Args>(__args)...); } ..... .....

My OS is Ubantu-16.04.7 LTS. I have tried to change the version of c++(11, 17) and libboost(all, 1.58)-dev. But the errors still exist. Do you have any ideas to solve it? Thanks.
