luwei@haode:~/tinyrpc/testcases$ g++ test_tinypb_server.cc ../lib/libtinyrpc.a -o test_tinypb_server -lprotobuf -ltinyxml -lpthread -ldl
/usr/bin/ld: /tmp/cckIA1Ib.o: in function QueryService::QueryService()': test_tinypb_server.cc:(.text._ZN12QueryServiceC2Ev[_ZN12QueryServiceC5Ev]+0x1f): undefined reference to vtable for QueryService'

我再使用了g++ test_tinypb_server.cc ../lib/libtinyrpc.a -o test_tinypb_server -lprotobuf -ltinyxml -lpthread -ldl编译之后QueryService()报错，应该如何解决。
