I am going to try to build protobuf from git source for armfs to verify if the old version protobuf caused the issue or not, the trouble is my protobuf code as all defined for protobuf v2, I don't want to run into the trouble with protobuf v3 source code, anyway I can defined to build v2 only during my build process?
