I am trying to generate client and server code in gRPC. I have installed grpc directory from github and trying to generate C++ code. I installed proto compiler 3.0.0.

When I am executing protoc i am getting below error

$ protoc -I ../../protos/ --grpc_out=. --plugin=protoc-gen-grpc=grpc_cpp_plugin ../../protos/helloworld.proto grpc_cpp_plugin: program not found or is not executable --grpc_out: protoc-gen-grpc: Plugin failed with status code 1.

Any idea why I am not able to generate client/server code

  • Do you have grpc_cpp_plugin? Is it executable? Commented Mar 2, 2016 at 7:29
  • I installed protoc 3.0.0 and then followed the way it was saying to run MAKE. But seems like it has not created cpp_plugin. Commented Mar 2, 2016 at 7:38

Check your /usr/local/bin. It should be there along with plugins for other languages.

/usr/local/bin > ll total 71144 -rwxr-xr-x 1 root root 12721867 Oct 23 10:44 grpc_cpp_plugin* -rwxr-xr-x 1 root root 14509678 Oct 23 10:44 grpc_csharp_plugin* -rwxr-xr-x 1 root root 13339870 Oct 23 10:44 grpc_objective_c_plugin* -rwxr-xr-x 1 root root 12569518 Oct 23 10:44 grpc_python_plugin* -rwxr-xr-x 1 root root 12393363 Oct 23 10:44 grpc_ruby_plugin*

If you do have other plugins but not cpp you probably overlooked something while installing.

If it's there try to specify full path when compiling (i.e. --plugin=protoc-gen-grpc=/usr/local/bin/grpc_cpp_plugin)

If you have multiple version of protobuf check if you use protoc and plugin from the same one.
