how to use antenna about gnss-sdr

[carlesfernandez]

You will need to use a SignalSource for a RF front-end. They are documented here: http://gnss-sdr.org/docs/sp-blocks/signal-source/#radio-frequency-front-ends

A working example with a USRP is at http://gnss-sdr.org/conf/

gnss-sdr: error while loading shared libraries: libboost_system.so.1.58.0: cannot open shared object file: No such file or directory

[carlesfernandez]

Did you uninstall the previous version and rebuild gnss-sdr from the scratch?
