When attempting to compile the latest github from
https://github.com/lomtax/digitalcoin it fails with the following error
CXXLD digitalcoind
libbitcoin_wallet.a(walletdb.o): In function `copy_file':
/usr/include/boost/filesystem/operations.hpp:381: undefined reference to `boost::filesystem::detail::copy_file(boost::filesystem::path const&, boost::filesystem::path const&, boost::filesystem::copy_option, boost::system::error_code*)'
collect2: error: ld returned 1 exit status
any ideas? this is under Ubuntu 14 LTS
PS: it compiles fine under Ubuntu 16 LTS
