How can I compile the biblepay src in a fast computer in Ubuntu and copy the compiled program to a slow computer and run? Which compile option should I use? Right now, I copied the compiled program and it says a lot of libraries are missing.
You should be able to run the executable on the slower machine (provided you didn't turn on any compile-time optimisations that are not compatible with that slower machine), however the executable does rely on a number of libraries. At a guess:
libdb4.8-dev libdb4.8++-dev
(or the self-compiled DB4 option)
libboost-all-dev libssl-dev libevent-dev
libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev
(but only if you compiled with the GUI enabled).
