The undefined reference errors means that you gave it headers for rocksdb but you forgot to give it the corresponding library flag that starts with -l like -lyour_rocksdb_library_name (I don't know what the rocksdb or go shim to rocksdb library you are using is called; you'll have to figure that out). For example to link the math library libm.so, you typically use the linker flag -lm (so the lib prefix part of the name gets replace with -l on the linker command line)
