Arrow can build against both static and dynamic protobuf. Looking at it, even when dynamically linking to Protobuf, the problematic `GetEmptyStringAlreadyInited` symbol mentioned in that issue still appears in libarrow_flight.so. One way would be to fold FlightSQL into libarrow_flight.so/libarrow_flight.a, that way there is no need to have two separate libraries that can both link Protobuf. (I wonder how you are supposed to be able to build multiple things relying on Protobuf though…) -- This is an automated message from the Apache Git Service.
