google/protobuf/runtime_version.h file not found

[ValeV008]

Hi,

I have an issue with changing example_server_protobuf.cpp to transmit .proto messages that I've defined.

I used protoc to create, and then copied myProto.pb.h and myProto.pb.cc files to foxglove-websocket/include/foxglove folder. Then I added #include "foxglove/myProto.pb.h" to example_server_protobuf.cpp. When I run nmake build, I get error 'google/protobuf/runtime_version.h' file not found in myProto.pb.h.

How can I solve this error and what is the correct way to change the example_server_protobuf.cpp?

Thanks!

Your build is not configured in a way to find the protobuf include file. Without knowing how you've structured the build setup it is hard to say more. Are you using the provided CMakeLists file in the examples repo?

Thanks for the response. Yes I use the CMakeLists from the examples. I noticed that the included protobuf library (from foxglove-websocket::foxglove-websocket) uses version 3.21.12, so I downloaded that version of protoc compiler, compiled my .proto file again and included new .pb.cc and pb.h files in the project. Now the project compiles fine. So I'm guessing it was version mismatch.

Btw, why does foxglove-websocket use such old protobuf lib version?

why is probably because we've not bothered to update the example to a newer version. If you want to make a PR updating the version and making sure the example works we'd be happy to review.

I understand. I will give it a try to update the examples. Thanks!
