error while loading shared libraries: libboost_program_options.so.1.58.0: cannot open shared object file: No such file or directory
-> sudo apt-get install libboost-all-dev
(overkill I feel)error while loading shared libraries: libqrencode.so.3: cannot open shared object file: No such file or directory
-> sudo apt-get install libqrencode3
error while loading shared libraries: libdb_cxx-4.8.so: cannot open shared object file: No such file or directory
