Import the "google/protobuf/empty.proto" and "google/protobuf/any.proto
Closed this issue · 6 comments
My .proto file import the "google/protobuf/empty.proto" and "google/protobuf/any.proto", like this:
syntax = "proto3";
import "google/protobuf/empty.proto";
import "google/protobuf/any.proto";
I use "make lcrd.grpc-c.c" generated file,when I use "make" to build the code ,I find the google/protobuf/empty.proto.h can not find.

I installed the libprotobuf-dev,my "/usr/local/include/google/protobuf" has these files ,but not have the empty.proto.h and any.proto.h

@ajhai Is it a bug in grpc-c that the generated file should not include google/protobuf/empty.proto.h but the other name?
@hqhq Yes. This is a bug in grpc-c compiler code. It should have generated empty.pb.h instead of empty.proto.h. Possibly coming from protobuf-c. Will take a look and fix this.
I have hit this too (IIRC file was generated as foo.pb-c.h but the #include wanted foo.proto.h). However, I am working in a project that also uses C++ gRPC bindings (which would generate a foo.pb.h file) so beware of name collisions. foo.pb-c.h might be the best to standardize on?
