I tried compiling grpc for cpp in an Ubuntu 16.04.02 virtual machine. Since the protobuf version supplied with grpc doesn't compile (unzip say one of the zip files is corrupt) I compiled protobuf 3.2.0 (which should be the right version to my understanding) myself from source, which worked fine.
When I now run make to compile grpc I get a lengthy error which has something to do with the fact that some files were generated with an older protoc version. (I add the full error message at the bottom). So my question is: is 3.2 the wrong protobuf version or is it a different problem? I also tried removing the protobuf directory from the third-party directory of grpc according to Need help to install c++ grpc on ubuntu 16.04 but it didn't change anyhting.
Thanks in advance!

This was an oversight from the time the reflection support was added. This problem shouldn't be there anymore with more recent versions of gRPC, as we are now generating these files at build time.
My suspicion is that you are trying to build an older version which had the problem. Please try updating :-)
