I got the following error when 'make'

$ make

This looks like a system problem: either /usr/bin/ranlib is missing (I hope not!) or the machine is out of resources (memory, available processes, file descriptors, ...) to start a new process. I'm not sure I can help with that -- hopefully someone else might have some suggestions.

As a low-probability attempt at a workaround (maybe building the shared library requires less resources?) you might try changing the first line of hanabi_lib/CMakeLists.txt from
add_library (hanabi hanabi_card.cc hanabi_game.cc hanabi_hand.cc hanabi_history_item.cc hanabi_move.cc hanabi_observation.cc hanabi_state.cc util.cc canonical_encoders.cc)
to
add_library (hanabi SHARED hanabi_card.cc hanabi_game.cc hanabi_hand.cc hanabi_history_item.cc hanabi_move.cc hanabi_observation.cc hanabi_state.cc util.cc canonical_encoders.cc)
and re-configure / re-build
cmake .; make

Neil, I think you're right. I tried it on another computer without any problem. Thank you!
