RPC with protocol buffers

问题:

I'm tring to make rpc with protocol buffers and zeromq. Here is my proto file:

message SearchRequest {
  required string query = 1;
}

message SearchResponse {
  repeated Result result = 1;
}

message Result {
  required string url = 1;
  optional string title = 2;
  repeated string snippets = 3;
}

service SearchService {
  rpc Search (SearchRequest) returns (SearchResponse);
}

According to the tutorial I should get some service interface code and stubs for this rpc but I don't. Did I misunderstand something or am I doing it wrong?

I generate sources with $ protoc test.proto --cpp_out=gen-cpp and get test.ph.cc/h without SearchService in content.

I did not do it on my own but it seems like your file is missing an option like option cc_generic_services = true; Look at the manual
