[grpc-io] Re: How to resolve potential grpc::ClientBidiReactor data racing

['AJ Heller' via grpc.io]

Hi Zhanhui,

Just in case, please read through the callback API spec to refamiliarize 
yourself: 
https://github.com/grpc/proposal/blob/master/L67-cpp-callback-api.md

Note that you can only have one outstanding read or write at a time. If you 
are calling StartWrite while a previous write's OnWriteDone method has not 
yet been called, that's improper use of the API (and effectively undefined 
behavior).

I hope this helps!

Best,

[grpc-io] Re: Plugin failed with status code

Did you follow the quickstart guide to build and install gRPC and protocol 
buffers using cmake? https://grpc.io/docs/languages/cpp/quickstart/
