Why would this error occur? Can you update the install instructions with more details on installing grpc correctly?
Have you tried just running apt-get install libgrpc+±dev protobuf-compiler-grpc ?
That should install all the required dependencies on a recebt Ubuntu image. If that doesn’t work then check the installed version of grpc.
That looks like you’re using an old compiler to me (older than GCC 9 at least). We did some work in 0.12 for compatibility with GCC 10 and that is the recommended compiler. GCC 9 will most likely work too, but not GCC 8.
