SEGFAULT in greeter_client

[gautham....@gmail.com]

Hi all,

I just cloned and built gRPC (SHA 9ed8734efb9b1b2cd892942c2c6dd57e903ce719). I'm getting SEGFAULT when I try to run greeter_client in C++. It SEGFAULTs when the RPC call is made -

Status status = stub_->SayHello(&context, request, &reply);

Here's how I'm building greeter_client -

cmake_minimum_required(VERSION 3.13)

project(HelloWorld)

set(CMAKE_CXX_STANDARD 17)

set(GRPC_BUILD_DIR

        /Users/gautham/projects/github/grpc)

set(LIB_GRPC

        ${GRPC_BUILD_DIR}/libs/opt/libgpr.dylib

        ${GRPC_BUILD_DIR}/libs/opt/libaddress_sorting.dylib

        ${GRPC_BUILD_DIR}/libs/opt/libgrpcpp_channelz.dylib

        )

set(LIB_PROTOBUF

        ${GRPC_BUILD_DIR}/third_party/protobuf/src/.libs/libprotoc.dylib

        )

include_directories(

        ${GRPC_BUILD_DIR}/include

)

add_executable(greeter_client

        greeter_client.cc

        helloworld.grpc.pb.cc

        helloworld.pb.cc

        )

target_link_libraries(greeter_client

        ${LIB_GRPC}

        ${LIB_PROTOBUF}

        )

Can anyone please help me?

Thanks,
